    (What is a Work Item?)

    Developed by Subcommittee: D02.B0.01 | Committee D02 | Contact Staff Manager


    1. Scope

    1.1 This test method is commonly referred to as the Sequence VH test, and it has been correlated with the Sequence VG test. The Sequence VG test was previously correlated with vehicles used in stop-and-go service prior to 1996, particularly with regard to sludge and varnish formation . It is one of the test methods required to evaluate oils intended to satisfy the API SN, SN Plus performance category. 1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.2.1 ExceptionWhere there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing size, or specified single source equipment. 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.
