9 - APPENDIX B - GUIDANCE ON THE USE OF STRIKES AND UNDERCOATS PRIOR TO RHODIUM PLATING

Specifies six coating thicknesses and gives recommended applications for each grade, on a range of base metals. Requirements cover condition of items before coating, heat treatment before and after coating, hardness, adhesion, reflectivity and sampling. Purchasing guidelines and guidance on the use of strikes and undercoats prior to rhodium coating are given in appendices.

This standard specifies requirements for electroplated coatings of rhodium on metallic substrates for general engineering applications.NOTE: Guidelines to purchasers on requirements that must be specified and/or agreed at the time of enquiry or order are given in Appendix A.
