Automotive Lubricant Standards
Automotive lubricant standards deal with the evaluation of lubricant properties and characteristics for classification and testing purposes, as well as their compatibility with the other components that they will come in contact with, such as oil seal elastomers. Developed by SAE and ASTM, automotive lubricant standards provide a backbone for interoperability between other components and lubricants from different manufacturers.
SAE J 310-2020
Automotive Lubricating Greases
This SAE Recommended Practice was developed by SAE, and the section “Standard Classification and Specification for Service Greases” cooperatively with ASTM and NLGI. It is intended to assist those concerned with the design of automotive components, and with the selection and marketing of greases for the lubrication of certain of those components on passenger cars, trucks, and buses. The information contained herein will be helpful in understanding the terms related to properties, designations, and service applications of automotive greases.
ASTM D7038-21a
Standard Test Method for Evaluation of Moisture Corrosion Resistance of Automotive Gear Lubricants
1.1 This test method covers a test procedure for evaluating the rust and corrosion inhibiting properties of a gear lubricant while subjected to water contamination and elevated temperature in a bench-mounted hypoid differential housing assembly. 2 This test method is commonly referred to as the L-33-1 test. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2.1 Exceptions - (1) where there is no direct SI equivalent such as screw threads and national pipe threads/diameters, and (2) the values stated in SI units are to be regarded as standard for the definitions in 12.2 , and for SI units where there are no direct inch-pounds equivalent units. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM D5662-19a
Standard Test Method for Determining Automotive Gear Oil Compatibility with Typical Oil Seal Elastomers
1.1 This test method 2 covers the determination of the compatibility of automotive gear oils with specific nitrile, polyacrylate, and fluoroelastomer oil seal materials. 1.2 Users of this test method should obtain Test Methods D412 , D471 , and D2240 and become familiar with their use before proceeding with this test method. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM D7603-13
Standard Test Method for Determination of Storage Stability and Compatibility in Automotive Gear Oils
1.1 This test method covers the determination of storage stability characteristics and the compatibility of automotive gear lubricants when blended with reference lubricants. The purpose of the test is to determine if performance-enhancing additives separate out under defined conditions. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
SAE J 1751-1995 (SAE J1751-1995)
Lubrication Components and Systems Used on Machine Tools and equipment for the Automotive Industry
These recommended practices are applicable for lubricating components and systems supplied on machines and equipment used in the automotive industry; for the purpose of this document, any equipment dispensing lubricant used in manufacturing and/or assembly processes. These practices do not apply to injection lubrication of pneumatic components.
SAE J 306-2019
Automotive Gear Lubricant Viscosity Classification
This SAE Standard defines the limits for a classification of automotive gear lubricants in rheological terms only. Other lubricant characteristics are not considered.
ASTM D4950-19
Standard Classification and Specification for Automotive Service Greases
1.1 This specification covers lubricating greases suitable for the periodic relubrication of chassis systems and wheel bearings of passenger cars, trucks, and other vehicles. 1.2 This specification defines the requirements used to describe the properties and performance characteristics of chassis greases and wheel bearing greases for service-fill applications. 1.3 The test requirements (acceptance limits) given in this specification are, as the case may be, minimum or maximum acceptable values for valid duplicate test results. Apply no additional corrections for test precision, such as described in Practice D3244 , inasmuch as the precision of the test methods was taken into account in the determination of the requirements. 1.4 The values stated in SI units are to be regarded as standard. 1.4.1 Exceptions Test Method D2596 reports test results in kgf units, and Test Method D4289 reports rubber hardness in Durometer Shore A units. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
SAE J 2360-2021
Automotive Gear Lubricants for Commercial and Military Use
The gear lubricants covered by this standard exceed American Petroleum Institute (API) Service Classification API GL-5 and are intended for hypoid-type, automotive gear units, operating under conditions of high-speed/shock load and low-speed/high-torque. These lubricants may be appropriate for other gear applications where the position of the shafts relative to each other and the type of gear flank contact involve a large percentage of sliding contact. Such applications typically require extreme pressure (EP) additives to prevent the adhesion and subsequent tearing away of material from the loaded gear flanks. These lubricants are not appropriate for the lubrication of worm gears. Appendix A is a mandatory part of this standard. The information contained in Appendix A is intended for the demonstration of compliance with the requirements of this standard and for listing on the Qualified Products List (QPL) administered by the Lubricant Review Institute (LRI). Appendix A contains a summary of key qualification requirements. A complete listing of qualification requirements and procedures can be found in the Program Document (PD4000), Gear Lubricant Review Program, available on the Performance Review Institute (PRI) website, www.p-r-i.org .
