Superseeded by:

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- enedinitrilo) Tetraacetate Titrimetric Test Method 70 to 77 Copper by the Combined Electrodeposition Gravimetric and Oxalyldihydrazide Photometric Test Method [50 %, minimum] 9 to 18 Iron by the 1,10-Phenanthroline Photometric Test Method [0.003 to 1.25 %] 18 to 27 Lead by the Atomic Absorption Test Method 89 to 99 Lead by the (Ethylenedinitrilo)tetraacetic Acid (EDTA) Titrimetric Test Method [2.0 to 30.0 %] 28 to 35 Nickel by the Dimethylglyoxime Extraction Photometric Test Method [0.03 to 5.0 %] 36 to 45 Nickel by the Dimethylglyoxime Gravimetric Test Method [4 to 50 %] 54 to 61 Silver in Silver-Bearing Copper by the Atomic Absorp- tion Test Method 100 to 111 Tin by the Iodatimetric Titration Test Method [0.5 to 20 %] 62 to 69 Zinc by Atomic Spectrometry 62 to 69 Zinc by the (Ethylenedinitrilo)tetraacetic Acid (EDTA) Titrimetric Test Method [2 to 40 %] 46 to 53

1.3 This standard does not purport to address all of the safety problems, 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 hazard statements are given in Section 5, Note 4, and Section 106.
