Organization: ASTM International
Publication Date: 1 January 1996
Status: inactive
Page Count: 7
ICS Code (Chemical analysis of metals): 77.040.30
ICS Code (Copper and copper alloys): 77.120.30
scope:

1.1 These test methods cover procedures for the chemical analysis of copper-nickel and copper-nickel-zinc alloys having chemical compositions within the following limits:

Element Concentration Range, % Copper 40 and over Nickel A 10 to 50 Zinc B 0 to 40 Lead 0 to 15 Tin 0 to 10 Iron 0.00 to 2 Manganese 0.00 to 2 Cobalt 0.00 to 0.5 A Includes cobalt. B In the case of copper-base alloys containing 5 % and over of zinc, the zinc is usually calculated by difference.

Whenever possible the technique and procedures for analysis should be checked against a National Institute of Standards and Technology standard sample having a composition comparable to the material being analyzed.

1.2 The test methods appear in the following order:

Sections Cobalt: Alpha-Nitroso-Beta-Naphthol Method 26 to 28 Nitroso-R-Salt (Photometric) Method 29 to 37 Copper, or Copper and Lead Simultaneously, by the 2a Electrolytic Method Iron: Dichromate Method 38 to 40 Thiocyanate (Photometric) 2a Method Salicylate (Photometric) 2a Method Lead: Electrolytic Method 12 to 15 Sulfate Method 2b Manganese: Persulfate Method 2b Periodate (Photometric) 59 to 66 Method Nickel by the Dimethylglyoxime Method 2a Tin by the Iodimetric Titration Method 2b Zinc by the Oxide or Ferrocyanide Method 2a

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. For precautions to be observed in these test methods, refer to Practices E50.
