Standard Test Methods for Chemical Analysis of Copper Alloys
ASTM E478-24
Organization:
ASTM - ASTM International
Year: 2024
Abstract: 4.1 These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with composition 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.

| scope | 1.1 These test methods cover the chemical analysis of copper alloys having chemical ranges within the following limits:2 Element Composition, % 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 sections: Sections Aluminum by the Carbamate Extraction-(Ethyl- enedinitrilo) Tetraacetic Acid Disodium Salt (EDTA) Titrimetric Test Method [2 % to 12 %] 71 – 78 Copper by the Combined Electrodeposition Gravimetric and Oxalyldihydrazide Spectrophotometric Test Method [50 %, minimum] 10 – 18 Iron by the 1,10-Phenanthroline Spectrophotometric Test Method [0.003 % to 1.25 %] 19 – 28 Lead by Atomic Absorption Spectrometry [0.002 % to 15 %] 90 – 100 Lead by the (Ethylenedinitrilo) Tetraacetic Acid, Disodium Salt (EDTA) Titrimetric Test Method [2.0 % to 30.0 %] 29 – 36 Nickel by the Dimethylglyoxime Extraction Spectrophotometric 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 Iodometric Titration Test Method [0.5 % to 20 %] 63 – 70 Tin by the Phenylfluorone Spectrophotometric Test Method [0.01 % to 1.0 %] 113 – 123 Zinc by Atomic Absorption Spectrometry [0.02 % to 2 %] 79 – 89 Zinc by the (Ethylenedinitrilo) Tetraacetic Acid Disodium Salt (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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
