    1. Scope

    1.1 These test methods cover the chemical analysis of sulfonated and sulfated oils. The analytical procedures appear in the following order:

    Section Moisture: Test Method A. Water by Distillation with Volatile Solvent 4 to 9 Test Method B. Moisture and Volatile Matter by Hot-Plate Method 10 to 14 Organically Combined Sulfuric Anhydride: Test Method A. Titration Test 15 to 19 Test Method B. Extraction-Titration Test 20 to 24 Test Method C. Ash-Gravimetric Test (in the Presence of True 25 to 28 Sulfonates) Total Desulfated Fatty Matter 29 to 32 Total Active Ingredients 33 to 36 Unsaponifiable Nonvolatile Matter 37 to 41 Inorganic Salts 42 to 46 Total Alkalinity 47 to 49 Total Ammonia 50 to 52 Acidity as Free Fatty Acids or Acid Number: Test Method A. In the Absence of Ammonium or Triethanolamine 53 to 56 Soaps Test Method B. In the Presence of Dark Colored Oils but in the 57 to 60 Absence of Ammonium or Triethanolamine Soaps (Brine Test) Test Method C. In the Presence of Ammonium or Triethanolamine 61 to 63 Soaps Water-Immiscible Organic Solvents Volatile with Steam 64 to 70

    1.2 The values stated in inch-pound units are to be re- garded 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.
