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:

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

Includes cobalt.

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 Method26 to 28
Nitroso-R-Salt (Photometric) Method29 to 37
Copper, or Copper and Lead Simultaneously, by the Electrolytic Method²a
Iron:
Dichromate Method38 to 40
Thiocyanate (Photometric)Method²a
Salicylate (Photometric)Method²a
Lead:
Electrolytic Method12 to 15
Sulfate Method² b
Manganese:
Persulfate Method² b
Periodate (Photometric)Method 59 to 66
Nickel by the Dimethylglyoxime Method²a
Tin by the Iodimetric Titration Method²b
Zinc by the Oxide or Ferrocyanide Method 2a
