ASTM D5354-95

Standard Test Method for Determination of Total Active Ingredients in Sulfonated and Sulfated Oils

SCOPE
1.1 This test method covers the determination of the total active ingredients in a sample of sulfonated or sulfated oil, or both, as it exists in the original sample by extracting the undecomposed sulfonated or sulfated fat and other fatty matter over an acidified concentrated salt solution. Free alkali or alkali bound as soap is not included. This test method was derived from Test Methods D500.
Note 1—In the case of sulfated oils only, this determination may also be estimated by calculation (see 6.3), as it is equivalent to the sum of the desulfated fatty matter and neutralized organically combined sulfuric anhydride.
1.2 The values stated in SI units are to be regarded as the 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.
