WITHDRAWN, NO REPLACEMENT
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jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in March 2010. This standard was withdrawn without replacement due to its limited use by the industry.
1.1 These test methods cover procedures for the chemical analysis of copper-nickel and copper-nickel-zinc alloys having chemical compositions within the following limits:
|Copper||40 and over|
|Nickel||10 to 50|
|Zinc||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|
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:
|Alpha-Nitroso-Beta-Naphthol Method||26 to 28|
|Nitroso-R-Salt (Photometric) Method||29 to 37|
|Copper, or Copper and Lead Simultaneously, by the Electrolytic Method||2a|
|Dichromate Method||38 to 40|
|Electrolytic Method||12 to 15|
|Sulfate Method||2 b|
|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.
