本标准等同采用ISO4525:2003(E)((塑料上镍+铬电镀层》(英文版)。

本标准根据ISO4525;2003(E)翻译起草，本标准对应ISO4525作了如下修改:

—按国内现有的覆盖层系列标准习惯，标准名称前加上“金属覆盖层，’:

—取消了国际标准的前言，增加了我国标准前言;

—为便于使用，引用了采用国际标准的我国标准;

—用“本标准”代替“本国际标准”

本标准代替GB/T12600-1990((金属覆盖层塑料上铜+镍+铬电镀层》和GB/T12610-1990

《塑料上电镀层热循环试验》。

本标准与GB/T12600-1990和GB/T12610-1990相比，主要变化如下:

—补充了引言;

—修改了适用范围;

—修改了使用条件号的说明;

—增加了延展性镍的有关要求;

—采用ISO4525合并上述两标准，重新修订了各章节。

本标准附录A、附录C、附录D、附录E、附录F、附录G为规范性附录，附录B为资料性附录。

本标准由中国机械工业联合会提出。

本标准由全国金属与非金属覆盖层标准化技术委员会归口。

本标准起草单位:武汉材料保护研究所、广州电器科学研究所、浙江新丰企业有限公司。

本标准主要起草人:贾建新、何杰、李大旭、郑秀林。、

本标准所代替标准的历次版本发布情况为:

金属覆盖层塑料上镍十铬电镀层

范围

本标准规定了塑料上有或无铜底镀层的镍+铬装饰性电镀层要求。本标准允许使用铜或者延展性

镍作为底镀层以满足热循环试验要求。

本标准不适用于工程塑料上的电镀层。
