    Significance and Use

    This test method is intended for use in the determination of the unsaponifiable, nonvolatile matter contained in sulfated oils for the purpose of quality assurance.

    1. Scope

    1.1 This test method covers the determination of the unsaponifiable, nonvolatile (above 80°C) matter existing in a sample of sulfated oil by saponifying the desulfated fatty matter and extracting the unsaponifiable matter, and extracting the unsaponifiable matter from the soap solution with ethyl ether.

    1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.3 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.
