Specifications for mould plates of CC 1 Scope This standard specifies the materials, machining and electroplating technical requirements, test methods, inspection rules and packaging requirements for mould plates of CC. This standard is applicable to the manufacture of copper-chromium-zirconium, copper-silver and copper-nickel-beryllium plates for mould of CC and chromium, nickel, ferro-nickel, nickel-cobalt and cobalt-nickel electroplated coatings. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this standard. However parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition applies.
