1.1 These test methods describe the procedures for the chemical analysis of industrial metal cleaning compositions in solid, paste, or liquid form. These cleaning compositions may contain caustic alkalies, silicates, phosphates, chromates, carbonates, bicarbonates, borates, sulfates, sulfites, nitrates, chlorides, soaps, rosin, sulfonated wetting agents, anti-foaming agents, organic bases, organic solvents, organic coupling agents, and sometimes inorganic acid salts or organic acids. Occasionally, such cleaning compositions may contain sulfonated oils; in such cases, reference should be made to Method D500. The examination under a low power microscope or magnifying glass, supplemented by a few qualitative tests, will often indicate the number of components and their identity.
1.2 The analytical methods appear in the following order:
Section Preparation of Sample 4 Total Alkalinity as Na2O 5 to 7 Total Fatty Acids (and Rosin) 8 and 9 Na2O Na[inf]2[r]O 5 to 7 Total Fatty Acids (and Rosin) 8 and 9 Na[inf]2[r]O Combined with Fatty Acids (and Rosin) 10 and 11 Anhydrous Soap 12 Rosin (McNicoll Test Method): Qualitative 13 and 14 Quantitative 15 to 18 Total Silica Calculated as SiO[inf]2[r] 19 to 22 Phosphates: Qualitative 23 and 24 Quantitative 25 to 32 Combined Sodium and Potassium Oxides 33 to 36 Chlorides 37 to 39 Sulfates 40 to 42 Water Distillation Test Method 43 to 46 Carbon Dioxide by Evolution-Absorption Test Method 47 to 51 Loss at 105[deg]C 52 and 53 Total Matter Insoluble in Alcohol 54 to 56 Free Alkali 57 to 59 Synthetic Detergent or Wetting Agent 60 and 61 Volatile Hydrocarbons 62 to 66 Loss on Ignition 67 and 68 Report 69 and 70
1.3 This standard does not purport to address all of the safety problems, 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.
