【国外标准】 Standard Test Methods for Sampling and Chemical Analysis of Soaps and Soap Products (Withdrawn 2023)

3.1 Soap and soap products are widely used. These test methods are suitable for setting specifications and performing quality control on soap and soap products.1.1 These test methods cover the sampling and chemical analysis of cake, powdered, flake, liquid, and paste soaps, and soap products.1.2 The test methods appear in the following order:Sampling  SectionGeneral Requirements  4Cake Soaps, Flake and Powdered Soap Products when Packed in Cans or Cartons  5Flake and Powdered Soap Products when in Bulk  6Liquid Soap  7Paste Soap Products  8Preparation of Samples  9Test Methods for Chemical AnalysisSafety Precautions 10Purity of Reagents 11Duplicate Tests 12Moisture: Choice of Method 13 Method A—Matter Volatile at 105°C (Oven Method) 14 Method B—Distillation Method 15 – 18Total Matter Insoluble in Alcohol 19 and 20Free Alkali or Free Acid 21Matter Insoluble in Water 22Total Alkalinity of Matter Insoluble in Alcohol, Alkaline Salts 23Combined Alkali, Total Anhydrous Soap 24 and 25Combined Sodium and Potassium Oxides 26 – 29Free Alkali and Potassium Carbonate in Potash Paste Soaps 30 – 32Unsaponified plus Unsaponifiable Matter 33 – 35Unsaponifiable Matter 36 – 38Unsaponified Matter 39Rosin (McNicoll Method) 40 – 43Preparation of Total Fatty Matter, Fatty and Rosin Acids, and Unsaponified Matter 44 and 45Titer Test 46 and 47Acid Number of Fatty Acids 48 and 49Iodine Number (Wijs Method) 50 – 52Chlorides 53 – 55Borax 56 – 58Silica Present as Alkaline Silicates 59 and 60Carbon Dioxide (Carbonates):   Train-Absorption Method 61 – 64 Evolution-Volumetric Method 65 – 68Phosphates 69 – 76Tetrasodium Pyrophosphate 77 – 79Sulfates 80 and 81Glycerine, Sugars, and Starch:   Glycerine in the Absence of Sugars 82 – 84 Glycerine in the Presence of Sugars 85 and 86 Starch 87 and 88 Sugars 89 and 90 Volatile Hydrocarbons 91 – 95 Copper (Trace Amounts)  96 – 102 Precision and Bias 1031.3 The values stated in inch-pound units are to be regarded as standard.
