1.1 These test methods cover the chemical analysis of cadmium having chemical compositions with the following limits:
| Element | Composition, 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 Spectrophotometric Method [0.0002 % to 0.0010 %] | 62-72 |
| Arsenic by the Molybdenum Blue Spectrophotometric Method [0.001 % to 0.005 %] | 40-50 |
| Copper by the Neocuproine Spectrophotometric 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 Spectrophotometric Method [0.001 % to 0.05 %] | 20-29 |
| Thallium by the Rhodamine B Spectrophotometric Method [0.0003 % to 0.005%] | 30-39 |
| Tin by the 8-Quinolinol Spectrophotometric 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, 25.8, 35.2, and 35.3.
