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:

Includes cobalt.
ElementConcentration Range,%
Copper40 and over
Nickel10 to 50
Zinc0 to 40
Lead0 to 15
Tin0 to 10
Iron0.00 to 2
Manganese0.00 to 2
Cobalt0.00 to 0.5

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:

Periodate (Photometric)Method

Sections

Cobalt:
Alpha-Nitroso-Beta-Naphthol Method26 to 28
Nitroso-R-Salt (Photometric) Method29 to 37
Copper, or Copper and Lead Simultaneously, by the Electrolytic Method

2a

Iron:
Dichromate Method38 to 40
Thiocyanate (Photometric)Method

2a

Salicylate (Photometric)Method

2a

Lead:
Electrolytic Method12 to 15
Sulfate Method

2 b

Manganese:
Persulfate Method

2 b

59 to 66
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 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. For precautions to be observed in these test methods, refer to Practices E 50.
