Test Method C. In the Presence of Ammonium or Triethanolamine Soaps61-63
Water-Immiscible Organic Solvents Volatile with Steam64-70

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.

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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.


These test methods cover the chemical analysis of sulfonated and sulfated oils. Water by distillation with volatile solvent and moisture and volatile matter by hot-plate shall be tested to meet the requirements prescribed. Titration test, extraction-titration test, and ash-gravimetric test shall be performed to meet the requirements specified. Total desulfated fatty matter, total active ingredients, unsaponifiable non-volatile matter, inorganic salts, total alkalinity, and total ammonia shall be tested to meet the requirements prescribed. In the absence of ammonium or triethanolamine soaps test method, brine test method, and in the presence of ammonium or triethanolamine soaps test method shall be performed to meet the requirements prescribed. Water-immiscible organic solvents volatile with steam shall be tested to meet the requirements prescribed.
