本标准修改采用ISO2093:1986((锡电镀层技术规范和试验方法》(英文版)。

本标准根据ISO2093:1986重新起草，本标准对应ISO2093作了如下修改:

—按国内现有的覆盖层系列标准，标准名称前加上“金属覆盖层”;

—取消了国际标准的前言;

—为便于使用，引用了采用国际标准的我国标准;

—增加了规范性引用文件的引导语;

—用“本标准”代替“本国际标准”;

—按引用标准ISO2064:1996修改了“主要表面”的定义;

—因ISO9227代替了ISO3768，所以引用标准用对应ISO9227的GB/T10125,

本标准代替GB/T12599-1990《金属覆盖层锡电镀层))),

本标准与GB/T12599-199。相比，主要变化如下:

补充了引言;

删去了最小厚度的定义(原版的3.2条);

—第5,6,7,8,9,10章的顺序和部分内容有所调整;

—补充了附录B、附录C,

本标准的附录A、附录B为规范性附录，附录C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。

本标准主要起草人:贾建新、何邵新、李大旭、谢锐兵、熊刚、黄三豹

本标准所代替标准的历次版本发布情况为:

金属覆盖层锡电镀层

技术规范和试验方法

引言

本标准规定了金属制品防腐蚀和提高可焊性的锡镀层的要求.

执行本标准应考虑国家对食品工业用锡镀层的相关法规和条例。

附录C为用户提供了附加信息。

需方除规定本标准号外还应当提出4.1,4.2所规定的内容。

范围

本标准规定了金属制品上标称纯锡镀层的要求。被层可以是无光的、光亮的镀后状态，或电镀后以

熔融方法进行熔流处理的状态。

本标准不适用于:

a)螺纹零件;

b)镀锡铜丝;

c)未加工成型的板材、带材和线材上的锡镀层，或由它们制成的产品;

d)螺旋形弹簧上的锡镀层;

e)采用化学方法(浸、自催化或化学镀)获得的锡镀层;

f)抗拉强度大于1000MPa(或相应硬度)的钢表面的锡镀层，因为这类钢电镀时会产生氢脆。

规范性引用文件

下列文件中的条款通过本标准的引用而成为本标准的条款。凡是注日期的引用文件，其随后所有的

修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的各方研究是

否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本标准。
