(Test Method)Standard Test Methods for Chemical Analysis of Copper-Nickel and Copper-Nickel-Zinc Alloys (Withdrawn 2010)
Standard Test Methods for Chemical Analysis of Copper-Nickel and Copper-Nickel-Zinc Alloys (Withdrawn 2010)
SIGNIFICANCE AND USE
These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these test 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 procedures for the chemical analysis of copper-nickel and copper-nickel-zinc alloys having chemical compositions within the following limits:ElementConcentration Range,%Copper40 and overNickel10 to 50Zinc0 to 40Lead0 to 15Tin0 to 10Iron0.00 to 2Manganese0.00 to 2Cobalt0.00 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:SectionsCobalt:Alpha-Nitroso-Beta-Naphthol Method26 to 28Nitroso-R-Salt (Photometric) Method29 to 37Copper, or Copper and Lead Simultaneously, by the Electrolytic Method2aIron:Dichromate Method38 to 40Thiocyanate (Photometric)Method2aSalicylate (Photometric)Method2aLead:Electrolytic Method12 to 15Sulfate Method2 bManganese:Persulfate Method2 bPeriodate (Photometric)Method 59 to 66Nickel by the Dimethylglyoxime Method2aTin by the Iodimetric Titration Method2bZinc 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.
WITHDRAWN RATIONALE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.
