Applies to electroplated coatings of hard chromium on ferrous and non-ferrous metals, classified in five types of regular, crack-free and porous type coatings. Heat treatment procedures are included. Information to be supplied with the enquiry or order and information on the appropriate chromium thickness to specify for different applications are given in the appendices. Photomicrographs showing the different types and percentages of porosity are included for reference standards.

This standard specifies requirements for electroplated coatings of hard chromium on ferrous and non-ferrous metals for engineering applications.NOTE: Guidelines to purchasers on requirements that must be specified by the purchaser and those that must be agreed at the time of enquiry and/or order are given in Appendix A.
