    Withdrawn Rationale:

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

    Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in March 2010. This standard was withdrawn without replacement due to its limited use by the industry.

    1. 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.

    In the case of copper-base alloys containing 5 % and over of zinc, the zinc is usually calculated by difference.

    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

    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 Method2a
    Iron:
    Dichromate Method38 to 40
    Thiocyanate (Photometric)Method2a
    Salicylate (Photometric)Method2a
    Lead:
    Electrolytic Method12 to 15
    Sulfate Method2 b
    Manganese:
    Persulfate Method2 b
    59 to 66
    Nickel by the Dimethylglyoxime Method2a
    Tin by the Iodimetric Titration Method2b
    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.
