Abstract
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. 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.
Scope
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:

|  Quantitative | 16 – 19 |
| Total Silica Calculated as SiO2 | 20 – 23 |
| Phosphates: |
|
|  Qualitative | 24 and 25 |
|  Quantitative | 26 – 18 |
| Combined Sodium and Potassium Oxides | 34 – 37 |
| Chlorides | 38 – 40 |
| Sulfates | 41 – 43 |
| Water, Distillation Test Method | 44 – 47 |
| Carbon Dioxide by Evolution-Absorption Test Method | 48 – 52 |
| Loss at 105°C | 53 and 54 |
| Total Matter Insoluble in Alcohol | 55 – 57 |
| Free Alkali | 58 – 60 |
| Synthetic Detergent or Wetting Agent | 61 and 62 |
| Volatile Hydrocarbons | 63 – 67 |
| Loss on Ignition | 68 and 69 |
| Report | 70 and 71 |
