1. Scope

1.1 These test methods for analysis cover greases of the conventional type which consist essentially of petroleum oil and soap. The constituents which can be determined are soap, unsaponifiable matter (petroleum oil, etc.), water, free alkalinity, free fatty acid, fat, glycerin, and insolubles.

1.2 A supplementary test method is provided in the Appendix. This test method is intended primarily for application to greases containing thickeners which are essentially insoluble in -hexane, and to greases which cannot be analyzed by conventional methods because of the presence of such constituents as nonpetroleum fluids or nonsoap-type thickeners, or both. In some cases, these constituents can react with strong acid or alkaline solutions.

1.3 These test methods appear in the following order:

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 and health practices, and determine the applicability of regulatory limitations prior to use. For hazard statements, see Notes 3 through 22.

1.5 The values stated in SI units are to be considered the standard.
