John Deere has engineered the PowerTech PSS 13.5L (824 cu. in.) engine to meet the high expectations for fuel economy and performance that operators expect. Selective catalytic reduction (SCR) is an exhaust filter option that reduces NOx emissions. SCR technology increases in cylinder combustion temperatures to reduce particulate matter (PM) output but as a result of these higher combustion temperatures, it increases the NOx (smog) emission levels. To keep the NOx levels within acceptable standards, a urea-based additive, sometimes referred to as AdBlue® system or diesel exhaust fluid (DEF) is added into the exhaust stream to low NOx emission downstream of the engine. The urea mixes with engine exhaust gases in the catalytic converter. The resulting reaction of adding urea (NH3) (or purified fertilizer) into the exhaust stream and passing through a catalyst transforms the NOx which results in harmless nitrogen gas and water vapor. Series turbochargers Series turbocharging delivers higher power density, improved low-speed torque, and improved high-altitude operation. By splitting the compression of the charge air between two turbochargers, both can operate at peak efficiency and at slower rotating speeds. This lowers stress on turbocharger components and improves durability. Series turbocharging works when fresh air is drawn into the low-pressure turbocharger (fixed geometry), where air pressure is boosted. This pressurized or boosted air is then drawn into the high-pressure turbocharger (VGT or WGT), where air intake pressure is further raised. The high-pressure air is then routed to an air-to-air aftercooler, where the air is cooled and routed to the engine’s intake manifold.

1. High-pressure turbocharger
2. Low-pressure turbocharger

The PowerTech PSS 13.5L (824 cu. in.) utilizes two turbochargers – a variable geometry turbocharger (VGT) and a fixed geometry turbocharger, providing the torque rise and engine responsiveness to meet varying load conditions. Fresh air is first drawn into the low-pressure fixed geometry turbocharger and compressed to a higher pressure. The compressed air is then drawn into the high-pressure VGT where the air is further compressed. The compressed air is then routed to the charge air cooler, and then to the intake manifold. By splitting the work between two turbochargers, both can operate at peak efficiency and at a slower rotating speed. VGT The VGT is electronically controlled and hydraulically actuates the turbo vanes as required to maintain peak engine performance. The turbocharger’s vanes are in the exhaust flow. The opening or closing of the vanes changes the outlet volume and airflow speed against the turbocharger impeller. When exhaust flow is low, the vanes are partially closed. This partial closure increases the pressure against the turbine blades to make the turbine spin faster and generate more boost pressure. The ability to keep the airflow flowing at optimum levels provides more consistent engine boost pressure and the ability to respond to load quickly across the entire engine rpm range. This system is without turbo lag as can be found on some engines. Boost pressure in the intake manifold is controlled at its optimum point for added fuel economy and performance regardless of rpm or load. The overall benefits:

• Increased low rpm torque
• Quicker response to load
• Increased peak torque
• Improved fuel economy
• Improved performance at high altitudes

Air-to-air aftercooling Air-to-air aftercooling lowers the intake manifold air temperature and provides more efficient cooling while reducing cylinder firing pressure and temperatures for greater engine reliability. Since low temperature air is denser, a higher volume of air flows into cylinders so the engine can meet the increasing horsepower demands.

Electronic unit fuel injection system

Electronic unit fuel injection system on the 13.5 L (824 cu. in.) engine provides the following benefits:

• Variable timing control for improved emissions
• Better control at start of fuel injection for improved starting
• Elimination of nozzle service
• Camshaft-driven transfer pump draws fuel through the fuel filter
• The single fuel rail is a drilled passage in the head, eliminating the need for external lines for reduced service through the fuel filter

Engine control unit (ECU) – full authority electronic controls

This engine control unit uses signal inputs from sensors and pre-programmed performance modeling to control critical engine functions such as fuel quantity, injection timing, air-to-fuel ratio, multiple fuel injections, amount of cooled exhaust gas recirculation (EGR), and a host of other control parameters to deliver peak fuel economy and engine performance. Each injector is controlled individually by the ECU. The ECU turns the injector on and off during each firing cycle to control the fuel delivery into each cylinder. The ECU can sense engine speed and load changes at a rate of 100 times per second and respond instantly to them. Load and speed sensing allow each cylinder’s fuel delivery rate to be adjusted independently at the individual injector. With each injection cycle, the ECU can make the following adjustments on the go:

• Number of injections
• Fuel pressure in the common rail
• Start of injection
• Duration of injection

This management system is connected to the transmission allowing the engine and transmission to respond simultaneously. Cold weather and high altitude compensation are also precisely controlled for quality starts regardless of weather and proper power levels at high elevations. Noise reduction The injection system also contributes to the engine running at a decreased noise level by a process called pilot injection. The precise fuel injection capabilities allow a small amount of fuel to be injected early in the combustion process. This helps lessen the combustion knock that is commonly heard on many diesel engines. While the combustion noise reduction is most obvious at lower engine speed, pilot injection continues to function at any engine speed.

Vari-Cool™ system

The Vari-Cool fan drive system precisely controls the speed of the fan in relation to the cooling requirements to maximize efficiency of the engine. The Vari-Cool system is efficient for two primary reasons:

• The belt drive used in the Vari-Cool system transfers almost 100 percent of the power from the engine to the fan.
• The variable fan speed sheave is electronically controlled only operating at the necessary speed to cool the engine and other auxiliary components.

Vari-Cool is integrated into the hood design The Vari-Cool system is an integrated part of the hood design. Intake and outflow of air from the coolers is diverted to key openings in the hood structure. The design allows for airflow dispersion that lessens dust and crop kick-up by discharging the airflow away from the cab. How Vari-Cool works This electrohydraulic system uses variable speed drives. Actual fan speed is determined by the ratio differences of the top fan drive sheave to the bottom sheave. The electronic control unit monitors various sensor inputs from the tractor and automatically changes the sheave ratio to change the fan speed. Hydraulic oil pressure is directed to the pistons that push the top inner sheave out (A), to close the gap and create a larger working diameter. The bottom sheave (B) responds by compressing the coil spring, widening the gap between the two sheave halves, and creating a smaller working diameter to increase the fan speed. To slow the fan, the valve opens, allowing oil to leave the piston, widening the upper sheave halves. Automatic shutdown function This feature monitors engine coolant temperature, engine oil pressure, and transmission oil pressures while the transmission is in the park position, and the operator is out of the seat.  If any of the systems reach undesirable levels, the tractor will shut down, to help prevent further tractor damage.

Fully independent 1000-rpm PTO is available as a factory- or field-installed option.

• Available on all 9 Family Ag Tractors
• 4.45-cm (1-3/4-in.) diameter shaft

9R – When the PTO is on and ground speed is 0.5km/h (0.31 mph) or less; PTO is limited to 335 hp. 9RT – When the PTO is on and ground speed is 0.5km/h (0.31 mph) or less; PTO is limited to 329 hp. 9RX – When the PTO is on and ground speed is 0.5km/h (0.31 mph) or less; PTO is limited to 335 hp. See the specs page for model rated PTO horsepower. The PTO shield has three positions — neutral, up, and down. Use the neutral position when the PTO is connected and ready for use. Use the up position for added clearance when connecting the PTO shaft to the tractor. The down position is used when the PTO is not connected and extra visibility to the drawbar is desired.

Electrohydraulic PTO control

The 9 Series Tractors utilizes an electrohydraulic PTO engagement switch to activate the optional 1000-rpm PTO. If PTO option is not installed, a storage compartment is located on the rear of the tractor.

3-point hitch

The 9 Series Tractors are designed to maximize performance for different applications. The 9R, 9RT, and 9RX Tractors offer two different hitch options:

	9420R/9420RX	9470R/9470RT/9470RX	9520R/9520RT/9520RX	9570R/9570RT/9570RX	9620R/9620RX
Category 4N/3 with quik-coupler, all axle diameters	Optional – 6804 kg (15,000 lb)		Not available
Category 4N/3 with quik-coupler, 120-mm (4.7-in.) axles required	Optional – 9072 kg (20,000 lb)		Not available
Category 4/4N with quik-coupler, all diameters axles	Optional: 6804 kg (15,000 lb)
Category 4/4N with quik-coupler, 120-mm (4.7-in.) axle required	Optional: 9072 kg (20,000 lb)

CommandARM™ controls

To help boost productivity, a field-installed kit with 3-point hitch controls can be purchased. If this option is selected, control buttons will be located on the 9 Series Tractor’s CommmandARM to access individual hitch settings. There are three buttons — set, lock, and load depth. There is also a rotary encoder that allows for finite movements of the hitch. The rotary encoder is detented, so it clicks for each movement. Additionally, hitch adjustment controls are located under the CommandARM for raise/lower rate. Hitch load depth The load depth feature is a useful tool designed to increase performance in tillage applications. Load depth adjustments allow the operator to make adjustments to hitch draft responsiveness. Draft control helps maintain the operating depth in varying conditions, such as rolling terrain, and varying soil densities. An additional feature with load depth control is the hitch slip option.  Hitch slip uses wheel slip data to supplement the draft control system. If the wheels slip, the 3-point hitch lifts to allow the tractor wheels to maintain traction with the ground. Once the slip condition is no longer present, the hitch lowers to the required depth as determined by the hitch command and load depth settings. Both of these hitch command options are easily programmable in the CommandCenter display by pressing the load depth shortcut key, followed by using the thumbwheel and confirm key to dial in the desired settings.

Hitch, external remote control switch

For added operator convenience, a 3-point hitch remote control switch is located on top of the left rear fender for 9R, 9RT, and 9RX Tractors. The external remote switches enable the operator to raise and lower the 3-point hitch from behind the tractor while hooking to implements.

Dual hydraulic pump system

Optional high-flow hydraulics are available on 9 Series Tractors by ordering code 3270. The high-flow hydraulic system provides an additional 215 L/min (57 gpm) of flow for a total of 435 L/min (115 gpm). This system is ideal for hydraulic fan motor demands. This system is recommended for agricultural implements with continuous flow requirements. When maximum hydraulic pump capacity is reached, multiple functions will continue to operate at the same proportional flow rate. The 9 Series Ag High-Flow Tractors have two parallel hydraulic systems. The benefit of this system is that functions can be split between the two systems. Functions that require high flow and low pressure can be combined on one system (for example, air seeder fans, and planter motors). Functions that require high pressure and low-flow can be connected to the remaining system (for example, implement lift, fold, and constant down-pressure systems). Following these guidelines allows the hydraulic system to run cooler as it prevents both hydraulic pumps from running at high pressure. In general, pumps forced to run at both high pressure and high flows generate much more heat than a pump running at a lower flow or lower pressure. The system operates with two hydraulic pumps:

• Pump 1 – provides hydraulic flow of up to 215 L/min (58 gpm) to SCVs 1, 2, and 3. These SCVs are useful for operating lift/lower and other cylinder type hydraulic needs.
• Pump 2 – attaches in front of pump 1 and provides hydraulic flow of up to 215 L/min (57 gpm) to SCVs 4, 5, and 6. These SCVs are useful for operating hydraulic motors to drive air/fan or vacuum systems on seeding/planting equipment.
• All SCV oil returns to one common hydraulic reservoir.

Eight-section SCV stack for high-flow requirements

For applications requiring continuous high hydraulic flow or multiple 19.1-mm (3/4-in.) hydraulic connections, this SCV stack is designed to maximize efficiency of the hydraulic system while providing additional flow using 19.1-mm (3/4-in.) couplers. Arrangement of the 19.1-mm (3/4-in.) couplers are split between the tractor’s dual hydraulic pumps to even the hydraulic load on each pump. Increasing coupler size from 12.7 mm (1/2 in.) to 19.1 mm (3/4 in.) allows an additional 26.5 L/min (7 gpm) or 17 percent more hydraulic flow through each coupler and reduces backpressure for hydraulic functions such as dual fan motors associated with the Air Power™ 2 system equipped on John Deere C850 Air Carts. With three 19.1-mm (3/4-in.) couplers available, operators can connect to other high-demand functions such as raise/lower. The 19.1-mm (3/4-in.) couplers also allow higher fan motor speeds for high-rate applications and allow more power to the ground due to less restriction on the hydraulic system. NOTE: This SCV configuration is available on all double-reduction) axle 9420R to 9570R Tractors with high-flow hydraulics and all 9RX Tractors with high-flow hydraulics. This eight-section SCV stack does not include hydraulic Intelligent Power Management (IPM) software. Connections to 12.7-mm (1/2-in.) and 19.1-mm (3/4-in.) couplers are quick and simple for operators with a split SCV stack configuration at a comfortable connection height.

Regular service and maintenance are essential to the performance, productivity, and longevity of all farm machinery. Maximum uptime is an important element of productivity.

Simply open the drain valve on the bottom of the separator and drain accumulated water. NOTE: Cummins® QSX 15 L (915.4-cu in.) engines cannot be equipped with a severe-duty water separator; however, the fuel filter has separating capabilities like the primary filter on John Deere Power System engines.

Engine access

The tilt hood and side panel design provide additional engine compartment protection. The 9R, 9RT, and 9RX hoods feature the same design for access to engine components. Pull out the hood release (located on the front, left side) and tilt hood back to open. Engine side panels are quickly and easily removed for access to periodic maintenance items.

Transmission, hydraulic, and axle oil level

A sight glass for the transmission, hydraulic, and axle oil level is located at the back right side of the gudgeon, indicating proper oil levels, and an oil fill neck is located on the back right side of the gudgeon for the 9R and 9RX Tractors. The oil fill is located on the top of the common reservoir on the left side of the 9RT Tractor and a fill tube is located between the steps and engine of the tractor.

• Provides increased filter capacity compared to previous 9R and 9RT Tractors
• Transmission, hydraulic, and axle oil should be changed every 1500 hours
• Filter should be changed every 1500 hours unless filter restriction code occurs
• Daily and 10-hour inspections of the transmission hydraulic oil level are recommended

NOTE: The tractor should be off and parked on level ground with the hitch in the lowered position when checking the oil level.

• Sight glass observations will be significantly higher with hot oil temperatures and lower with cold oil or if engine has not run long enough.

NOTE: Oil level above the top mark on the sight glass can result in power loss and heat generation during transport applications.

Primary air filter access

On the 9R and 9RX, the primary engine air filter is accessible from the left-hand platform for replacement annually or as operating conditions require. The filter is aspirated and extends filter life in dusty conditions by aspirating more than 95 percent of incoming dust. Aspirator suction is created by utilizing the air flow from the cooling fan. On the 9RT, the primary engine air filter is located at ground level on right side of tractor.

Windshield washer

The windshield washer bottle is optional on 9R and 9RX Tractors and is located on the left side of the tractor near the DEF fill point. On 9RT Tractors, it is located on the right-side frame.

Oil change intervals

Tractors with the 9.0L (549.2-cu in.) and 13.5L (823.2-cu in.) John Deere Power Systems engines feature a 500-hour change interval when using approved John Deere Plus-50™ II oil and a John Deere oil filter. Tractors equipped with the Cummins QSX 15-L (915.4-cu in.) engine have a 400-hour engine oil and oil filter change interval.

• Previous initial oil and filter change at 100 hours is no longer required due to the factory fill of Break-In™ Plus oil.
• If using anything other than John Deere Plus-50 II oil, a 250-hour change interval is required.  CJ-4 must still be used.
• Only use ultra-low sulfur diesel fuel and CJ-4, ACEA E9, or ACEA E6 oil.
• An oil change of 500 hours is possible when using fuel with less than 15 parts per million (ppm) of sulfur, along with John Deere Plus-50 II oil.

See the tractor’s operator’s manual for oil change intervals and further details.

Battery access

The 9R and 9RX battery location is behind the left-hand step assembly. There are three bolts that secure the swinging step assembly that need to be removed to completely access the batteries. The 9RT top step of the platform conceals the tractor’s three 12-V batteries with 2775 CCA (925-CCA each). Tractors with the Cummins X15 engine will have four 12-V batteries in the same location as tractors equipped with John Deere Power System engines. Although the batteries are maintenance free, conditions such as long periods of operation at high ambient temperatures and excessive engine cranking may require adding water.

Battery boost terminal

On the 9R and 9RX, a battery boost terminal is located on the left-hand side of the engine for convenient and proper boost assisted starting.

Fuse and relay panel

The electrical fuse and relay panel is located behind the operator’s seat and just below the cab’s rear window. Simply lift up on the operator manual cover for access.

• Contains easy-to-replace automotive blade-type fuses and relays for quick servicing.
• Spare fuses are provided for each amperage size used.

The diode module contains many of the diodes contained in the system:

• If a diode problem occurs, simply replace the diode module for easy service and increased uptime.
• Relays are also fully interchangeable for quick service.

Electrical system (smart load center)  The electrical system provides a full controller area network (CAN) bus based system on the tractor for improved tractor implement integration and flexibility. Incorporated with the system is a smart load center, which provides fewer fuses, fewer connectors, and simplified wiring for increased reliability. The solid-state load center’s primary function is to control the majority of high-current loads, such as fender floodlights and the horn. This electronic circuitry will monitor loads and voltages to provide fast reaction time and the ability to alert the operator if a circuit overloads or if voltage is out of specification – for example, open circuit (undercurrent) or short circuit (overcurrent).

Cab air filters

The cab fresh air filter is conveniently located beneath the left side of the cab for all 9 Series products:

• External service means no mess in the cab from dusty filters
• Filter housing acts as a dust accumulator compartment
• Hand screw eliminates need for tools
• Replace cab fresh air filter every 1000 hours or sooner if plugged or damaged

Cab air recirculation filter Cab air recirculation filter is located in the roof liner above the operator. 70 percent of the total air volume is recirculated with a blanket effect for enhanced operator comfort.

• Replace cab air recirculation filter every 1000 hours or sooner if plugged or damaged.

Cab air filters are not designed to filter out harmful chemicals. Follow the instructions in the implement operator’s manual and those given by the chemical manufacturer when using agricultural chemicals.

Maintenance-free U-joint

Maintenance-free U-joint bearings require no servicing to reduce maintenance time.

Toolbox

A convenient toolbox is located on the left-hand side of the front frame for tool storage and comes standard on all 9R, 9RT, and 9RX Tractors. 9R and 9RX Tractors have an additional storage box conveniently located on top the left-hand platform. The 9RT has an additional toolbox conveniently located next to the left side of the batteries for additional storage. Cummins is a trademark of Cummins, Inc.

The e18 transmission delivers smooth shifting and intuitive controls in a reliable 18-speed PST transmission. The e18 transmission with enhanced Efficiency Manager is standard equipment on all 9 Series Tractors. The e18 has evolved from more than 50 years of John Deere PowerShift technology. With more automatic features, the e18 is easy to operate for all levels of operators and operations. It features three modes of operation, full AUTO, custom, and manual modes. Full AUTO and custom modes manage the engine and transmission to match the desired ground speed to the field conditions. These two modes are ideal for most conditions and take the guess work out of operation. Manual mode is perfect for operators looking to operate the e18 like a traditional PowerShift by bump shifting and managing the engine throttle to their liking. As the next generation of PowerShift technology, the e18 delivers the strength to handle sudden, high-torque power loads while maintaining responsive, quick, and smooth shifts.

e18 controls

CommandCenter™ controls

The CommandCenter is the central information system for tractors and allows the operator to program various settings tailored to a specific operation. To access the tractor’s transmission settings, press the transmission shortcut button on the CommandCenter shortcut bar. Operating modes The e18 application settings employ three modes to take full advantage of the engine-transmission communication: Full AUTO mode, custom mode, and manual mode.

Full AUTO mode

Full AUTO mode manages the tractor’s engine and transmission inputs to reach and maintain the desired ground speed set by the operator. This means the tractor will manage shifts and engine rpm to operate at the most efficient level possible. Operators can set the maximum forward and reverse speeds for their particular applications. In full AUTO mode the operator can adjust the desired ground speed in two ways, by conducting a traditional bump shift or by rotating the dial on the thumb wheel. When shifting in full AUTO mode, the transmission shifts set speeds and does not always shift gears, meaning the transmission may not necessarily shift gears if it can reach the desired ground speed with a slightly higher or lower engine rpm. Efficiency Manager is automatically engaged while operating in full AUTO mode. As a result, shifting will not take the tractor out of Efficiency Manager in full AUTO mode.

Custom mode

Custom mode operates similar to full AUTO mode but allows operators to adjust operating parameters to meet a specific operation. It can also activate eco mode for a higher level of operation. Eco allows two minimum engine speeds to be set. Operators can turn eco on and off by either pushing the eco button on the side of the throttle or by selecting eco in the transmission settings page of the CommandCenter controls. For example, operators may choose to turn eco on during transport to utilize a lower minimum engine speed and then turn eco off while operating in the field where a higher minimum engine speed is desired. In the advanced settings page, operators can customize the auto shift engine speed droop as a percentage of the full engine speed. In addition, the load anticipation feature can be enabled for the hitch engagement, hydraulic engagement, or both. Manual mode Manual mode operates very similarly to a traditional PowerShift transmission with Efficiency Manager. In manual mode the operator manages the engine and transmission inputs by controlling the shift lever and hand throttle. Efficiency Manager Efficiency Manager is automatically enabled in auto and custom modes. Efficiency Manager can be turned on in manual mode by selecting the set speed one or set speed two button on the CommandARM™ console. The set speed adjuster on the top of the single-lever gear selector allows the operator to dial in the desired ground speed to establish set speed one or two. Once engaged, Efficiency Manager will manage the engine rpm and gear selection to maintain the desired working speed. To reach the desired set speed, the throttle must be set to full engine rpm.

e18 operation

Setting start-up gears The 9 Series Tractors default to 7F and 2R at start up. However, these default start-up gears can be adjusted from 1-13F and 1-3R through the CommandCenter. Refer to the operator’s manual for additional information. 9R Tractor – e18-speed chart for PowerShift transmission (PST) with Efficiency Manager 9R table

9RX Tractors equipped with 45.7-cm (18-in.) and 61-cm (24-in.) tracks feature a maximum speed of 42 km/h (26 mph). 9RX Tractors equipped with 45.7-cm (18-in.) or 61-cm (24-in.) tracks are advised to reduce ground speed based on axle load. 9RX Tractors equipped with 45.7-cm (18-in.) tracks will have a top speed set at the factory of 31 km/h (19 mph). Maximum speed may be adjusted up to 42 km/h (26 mph) upon review of the transport speed recommendations in the Operator’s Manual. The speed reduction allows the undercarriage components and tracks to dissipate heat buildup caused by the higher axle loads, reducing undercarriage component and track damage. Increasing mid-roller surface area will increase the undercarriage ability to dissipate heat. Narrow undercarriage with 45.7-cm (18-in.) tracks feature a narrower mid-roller matched to track width. This results in a smaller mid-roller surface area than 61-cm (24-in.) tracks, which are also matched to track width. Producers who desire a 9RX machine for row-crop work and who also transport long distances with high axle loads should understand the limitations of the 45.7-cm (18-in.) and 61-cm (24-in.) tracks. 61-cm (24-in.) tracks with a greater mid-roller surface area will provide greater undercarriage and machine performance in transport while maintaining the ability to perform row-crop work. Comparing the transport speed recommendations for 45.7-cm (18-in.) and 61-cm (24-in.) tracks, the speed reduction is higher for 45.7-cm (18-in.) tracks for the same axle load. 9RX Tractors with a wide undercarriage and 76.2-cm (30-in.) or 91.4-cm (36-in.) tracks do not feature a speed reduction with increased axle load. 9RX Tractor owners and operators need to be aware of axle loads and the recommended speed. The operator’s manual for both the machine and implement will have information on advised transport speeds. 9RX Tractors equipped with narrow undercarriage will also feature an in-cab window decal and reference card stored in the armrest for quick guidance on recommended transport speed based on axle load. Many implements may have a lower recommended transport speed than the tractor; it is always advised to follow the lowest recommended transport speed.

NOTE: Example implements are for reference and direction only. Weigh the tractor and the amount of weight on the axle to determine the final recommended speed. Weights of implements will vary due to different configurations available between tractor and implement. Never exceed the maximum speed recommendation of any implement. For producers who wish to limit vehicle top speed, transmission settings can be adjusted on the CommandARM™ display or user profiles can be established which locks out the ability to change vehicle top speed by the operator unless they enter the PIN.

For countries not required to comply with Final Tier 4 (FT4)/Stage V emission regulations, John Deere also offers the reliable and proven PowerTech 13.5L (824-cu in.) Tier 2/Stage II engine. With this engine, John Deere meets high performance and low emission requirements while maintaining exceptional durability, reliability, and fuel economy. The PowerTech 13.5L (824-cu in.)

How is rated and maximum power determined?

John Deere uses a precise procedure to measure engine-only power levels. The 97/68EC standard is widely used worldwide in the agricultural industry and relates to the power a tractor has as a complete functioning unit. The 97/68EC standard is required in the European Union (EU). However, the procedure only requires that a production engine and radiator are used on a dynamometer test. See the engine horsepower standards information for more detailed explanations of the different standards.
