1.1 This specification covers requirements for electrodeposited gold coatings that contain not less than 99.00 mass % gold and that are used for engineering applications. 1.2 Specifically excluded from this specification are autocatalytic, immersion, and vapor deposited gold coatings. 1.3 Gold coatings conforming to this specification are employed for their corrosion and tarnish resistance (including resistance to fretting corrosion and catalytic polymerization), bondability, low and stable contact resistance, solderability, and infrared reflectivity. Several types of coatings, differing in gold purity and hardness, are covered by this specification. 1.4 The values stated in SI units are to be regarded as the standard. Values provided in parentheses are for information only. 1.5 The following hazards caveat pertains only to the test methods section, Section 9, of 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. |
