These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with compositional specifications. It is assumed that all who use these methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
1.1 These test methods cover the chemical analysis of copper alloys having chemical compositions within the following limits:
| Element | Concentration, % |
| Aluminum | 12.0 max |
| Antimony | 1.0 max |
| Arsenic | 1.0 max |
| Cadmium | 1.5 max |
| Cobalt | 1.0 max |
| Copper | 40.0 min |
| Iron | 6.0 max |
| Lead | 27.0 max |
| Manganese | 6.0 max |
| Nickel | 50.0 max |
| Phosphorus | 1.0 max |
| Silicon | 5.0 max |
| Sulfur | 0.1 max |
| Tin | 20.0 max |
| Zinc | 50.0 max |
1.2 The test methods appear in the following order:
| Sections | |
| Aluminum by the Carbamate Extraction-Ethyl- enedinitrilotetraacetate Titrimetric Test Method [2 % to 12 %] | 71-78 |
| Copper by the Combined Electrodeposition Gravimetric and Oxalyldihydrazide Photometric Test Method [50 %, minimum] | 10-18 |
| Iron by the 1,10-Phenanthroline Photometric Test Method [0.003 % to 1.25 %] | 19-28 |
| Lead by Atomic Absorption Spectrometry [0.002 % to 15 %] | 90-100 |
| Lead by the Ethylenedinitrilotetraacetic Acid (EDTA) Titrimetric Test Method [2.0 % to 30.0 %] | 29-36 |
| Nickel by the Dimethylglyoxime Extraction Photometric Test Method [0.03 % to 5.0 %] | 37-46 |
| Nickel by the Dimethylglyoxime Gravimetric Test Method [4 % to 50 %] | 55-62 |
| Silver in Silver-Bearing Copper by Atomic Absorption Spectrometry [0.01 % to 0.12 %] | 101-112 |
