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. Scope

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
Tin by the Iodotimetric Titration Test Method [0.5 % to 20 %]	63-70
Tin by the Phenylfluorone Photometric Test Method [0.01 % to 1.0 %]	113-123
Zinc by Atomic Absorption Spectrometry [0.2 % to 2 %]	79-89
Zinc by the Ethylenedinitrilotetraacetic Acid (EDTA) Titrimetric Test Method [2 % to 40 %]	47-54

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.

10.1 This test method covers the determination of copper in concentrations greater than 50 %.
