ASTM B 559 Document Information:
Title
Standard Specification for Nickel-Coated, Copper-Clad Steel Wire for Electronic Application
ASTM International
Publication Date:
Jul 15, 1993
Scope:
This specification covers nickel-coated, round, copper-clad
steel wire for electronic application.
Nickel coatings in mass percentages of the total mass of the
coated wire are as follows: 2, 4, 7, 10, and 27 %. Nickel-coated
wire having different minimum mass percentages of nickel may be
obtained by mutual agreement between the manufacturer and the
purchaser. For information purposes, the thickness of coating in
microinches provided by the percentages listed above is shown in
Table 1.
Four classes of nickel-coated, copper-clad steel wire are
covered as follows:
Class N30HS—Nominal 30 % conductivity, hard drawn.
Class N30A—Nominal 30 % conductivity, annealed.
Class N40HS—Nominal 40 % conductivity, hard drawn.
Class N40A—Nominal 40 % conductivity, annealed.
The values stated in inch-pound units are to be regarded as the
standard. The values given in parentheses are for information only,
except for resistivity, where the SI units are to be regarded as
the standard.
The following safety hazards caveat pertains only to the test
method described in this specification. 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.
(Warning—Consideration should be given to toxicity
and flammability when selecting solvent cleaners.)
