GB/T15757-2002前言本标准是根据国际标准ISO8785:1998《产品几何量技术规范(GPS>表面缺陷术语、定义及参数)(1998年版)，对GB/T15757-1995《表面缺陷术语、定义及参数》进行修订，在技术内容上与ISO8785:1998等效，编写规则上与之等同。本标准主要在以下内容修订:—增加了缩孔、(凹面)瓢曲、(凸面)瓢曲定义的相应图示;—对表面缺陷的特性和参数的代号做了改动。本标准与ISO8785的区别:—略去了ISO8785中的导言，与国家标准的编写规则相协调;—略去了ISO8785中的附录B(参考目录)。本标准自实施之日起，同时代替GB/T15757--1995,本标准的附录A是提示的附录。本标准由全国产品尺寸和几何技术规范标准化技术委员会提出并归口。本标准起草单位:中国机械科学研究院、时代集团公司、中国计量科学研究院、北京计量科学研究所、沈阳601所。本标准主要起草人:王欣玲、王忠滨、高思田、吴迅、王肇强、赵有祥 GB/"r15757-2002ISO前言ISO(国际标准化组织)是一个世界范围的国家标准化组织(ISO成员)的联合会，国际标准的制定工作通常由ISO各技术委员会进行。每个成员组织，对某一主题的技术委员会感兴趣，就有权参加该委员会工作，其他与ISO协作的政府间或非政府间的国际组织也可以参加工作。ISO与IEC(国际电工委员会)在所有有关电工技术标准化的内容上进行密切合作。由技术委员会提出的国际标准草案，散发给各成员组织，由各成员组织投票表决，至少需要75%的赞成票才能作为国际标准公布。国际标准ISO8785是由ISO/TC213《产品尺寸和几何技术规范》技术委员会制定的。本标准附录A是提示的附录。
