Scope
1.1 This engine lubricant test method is commonly referred
to as the Roller Follower Wear Test. Its primary result, roller
follower shaft wear in the hydraulic valve lifter assembly, has
been correlated with vehicles used in stop-and-go delivery
service prior to 1993. It is one of the test methods required to
evaluate lubricants intended to satisfy the API CG-4 performance category. This test has also been referred to as the 6.2 L
Test.
1.2 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.2.1 Exceptions—Where there is no direct SI equivalent,
such as pipe fittings, thermocouple diameters, and NPT screw
threads. Also, roller follower wear is measured in mils.
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.
