1.1 This specification covers nickel-coated, round, copper-clad steel wire for electronic application.<\/p>\n
1.2 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 .<\/p>\n
1.3 Four classes of nickel-coated, copper-clad steel wire are covered as follows:<\/p>\n
1.3.1 Class N30HS – Nominal 30 % conductivity, hard drawn.<\/p>\n
1.3.2 Class N30A – Nominal 30 % conductivity, annealed.<\/p>\n
1.3.3 Class N40HSNominal 40 % conductivity, hard drawn.<\/p>\n
1.3.4 Class N40A – Nominal 40 % conductivity, annealed.<\/p>\n
1.4 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.<\/p>\n
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.<\/i> (Warning-Consideration should be given to toxicity and flammability when selecting solvent cleaners.)<\/p>\n
