Full Description

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 - 9 Test Method B. Moisture and Volatile Matter by Hot-Plate Method 10 - 14 Organically Combined Sulfuric Anhydride: Test Method A. Titration Test 15 - 19 Test Method B. Extraction-Titration Test 20 - 24 Test Method C. Ash-Gravimetric Test (in the Presence of True
Sulfonates) 25 - 28 Total Desulfated Fatty Matter 29 - 32 Total Active Ingredients 33 - 36 Unsaponifiable Nonvolatile Matter 37 - 41 Inorganic Salts 42 - 46 Total Alkalinity 47 - 49 Total Ammonia 50 - 52 Acidity as Free Fatty Acids or Acid Number: Test Method A. In the Absence of Ammonium or Triethanolamine Soaps 53 - 56 Test Method B. In the Presence of Dark Colored Oils but in the
Absence of Ammonium or Triethanolamine Soaps (Brine Test) 57 - 60 Test Method C. In the Presence of Ammonium or Triethanolamine Soaps 61 - 63 Water-Immiscible Organic Solvents Volatile with Steam 64 - 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, health, and environmental 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. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
