description
Scope
1.1 These test methods cover the chemical analysis of cadmium having chemical compositions with the following limits:
| Element | Concentration, max, % |
| Antimony | 0.001 |
| Arsenic | 0.003 |
| Copper | 0.015 |
| Lead | 0.025 |
| Silver | 0.010 |
| Thallium | 0.003 |
| Tin | 0.010 |
| Zinc | 0.035 |
1.2 The test methods appear in the following order:
| Sections | |
| Antimony by the Rhodamine B Photometric Method [0.0002 to 0.0010%] | 62-72 |
| Arsenic by the Molybdenum Blue Photometric Method [0.001 to 0.005%] | 40-50 |
| Copper by the Neocuproine Photometric Method [0.002 to 0.030%] | 10-19 |
| Copper, Lead, Silver, and Zinc by the Atomic Absorption Method [0.004 to 0.02% Cu, 0.01 to 0.05% Pb, 0.004 to 0.02 % Ag and 0.01 to 0.05% Zn] | 51-61 |
| Lead by the Dithizone Photometric Method [0.001 to 0.05%] | 20-29 |
| Thallium by the Rhodamine B Photometric Method [0.0003 to 0.005%] | 30-39 |
| Tin by the 8-Quinolinol Photometric Method [0.0025 to 0.0150%] | 73-82 |
1.3 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. Specific precautionary information is given in Section 6 and 25.8.
