|ICS Code (Lubricants, industrial oils and related products):||75.100|
This test method covers and is commonly referred to as the Sequence VG test,2 and it has been correlated with vehicles used in stop-and-go service prior to 1996, particularly with regard to sludge and varnish formation.3 It is one of the test methods required to evaluate oils intended to satisfy the API SL performance category.
The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
Exception-Where there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing size, or specified single source equipment.
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. Specific hazard statements are given in 7.7, 220.127.116.11, 18.104.22.168, 22.214.171.124, 9.2.6, 126.96.36.199, 188.8.131.52, 184.108.40.206, and Annex A5.
