ASTM B634-88(2009) - 1.9.2009
 
1. Scope

1.1 This specification covers requirements for electrodeposited coatings of rhodium used for engineering purposes.

1.2 Coatings of rhodium covered by this specification are usually employed for their corrosion resistance, stable electrical contact resistance, wear resistance, reflectivity, and heat resistance.

1.3 Appendix X1 covers some typical applications for electrodeposited rhodium.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 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.
