【国外标准】 Standard Test Methods of Chemical Analysis of Industrial Metal Cleaning Compositions (Withdrawn 2023)

AbstractThese 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. Percentage of total sodium oxide, percentage of potassium oxide, percentage of free sodium hydroxide, percentage of water, percentage of losses, percentage of matter insoluble in alcohol, percentage of fatty acids, percentage of rosin, percentage of synthetic detergent or wetting agent, percentage of silica, percentage of phosphorus pentoxide, percentage of carbon dioxide, percentage of sodium chloride, percentage of sodium sulfate, and percentage of volatile hydrocarbons test methods shall be performed to conform with the specified requirements.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 4Total Alkalinity as Na2O 5 – 8Total Fatty Acids (and Rosin) 9 and 10Na2O Combined with Fatty Acids (and Rosin) 11 and 12Anhydrous Soap 13—Rosin (McNicoll Test Method):   Qualitative 14 and 15 Quantitative 16 – 19Total Silica Calculated as SiO2 20 – 23Phosphates:   Qualitative 24 and 25 Quantitative 26 – 18Combined Sodium and Potassium Oxides 34 – 37Chlorides 38 – 40Sulfates 41 – 43Water, Distillation Test Method 44 – 47Carbon Dioxide by Evolution-Absorption Test Method 48 – 52Loss at 105°C 53 and 54Total Matter Insoluble in Alcohol 55 – 57Free Alkali 58 – 60Synthetic Detergent or Wetting Agent 61 and 62Volatile Hydrocarbons 63 – 67Loss on Ignition 68 and 69Report 70 and 711.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 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. See 6.1 for a specific hazards statement.
