Standard Specification for Performance of Rear Axle Gear Lubricants Intended for API Category GL-5 Service
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers test methods and acceptance criteria for determining the acceptability of gear oils for applications which specify a lubricant meeting the performance requirements of API Category GL-5 service. Lubricants which meet these performance requirements are typically intended for use in automotive axles, particularly those containing hypoid gears, operating under various combinations of high-speed/shock-load and low-speed/high-torque conditions.
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.
1.3 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.
