1.1 These test methods cover the chemical analysis of the pigment commercially known as basic lead silicochromate and are applicable to pigment supplied by the manufacturer and to pigment, but not mixed pigments, separated from liquid coatings. The presence of basic lead silicochromate species shall be confirmed by X-ray diffraction analysis (see Specification D 1648
1.2 For liquid coatings the pigment must first be separated from the vehicle before conducting the analysis.
1.3 The analytical procedures appear in the following order:
| Sections | |
| Lead oxide | 6 to 14 |
| Chromium trioxide | 15 to 23 |
| Silica | 24 to 27 |
| Moisture and other volatile matter | 28 |
| Coarse particles | 29 |
| Oil absorption | 30 |
| Mass color and tinting strength | 31 |
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address 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.
