1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1.1 This specification covers the requirements for electroplated nickel coatings applied to metal products for engineering applications, for example, for use as a buildup for mismachined or worn parts, for electronic applications, including as underplates in contacts or interconnections, and in certain joining applications. 1.2 Electroplating of nickel for engineering applications (Note 1) requires technical considerations significantly different from decorative applications because the following functional properties are important: 1.2.1 Hardness, strength, and ductility, 1.2.2 Wear resistance, 1.2.3 Load bearing characteristics, 1.2.4 Corrosion resistance, 1.2.5 Heat scaling resistance, 1.2.6 Fretting resistance, and 1.2.7 Fatigue resistance. 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.
