前言
本标准是对GB/T13914-1992《冲压件尺寸公差》的修订。
修订时，参照GB/T15055-1994《冲压件未注公差尺寸的极限偏差》,DIN6930((钢冲压件一般公
差》和DIN6953((钢板制品的冷弯》的部分内容，对部分公差作了调整。并作了编辑性修改。
本标准自实施之日起，同时代替GB/T13914-1992,
本标准的附录A是标准的附录。
本标准由中国机械工业联合会提出。
本标准由全国锻压标准化技术委员会归口。
本标准负责起草单位:中国一拖集团有限公司冲压厂。
本标准主要起草人:王彤勇、王文惠、王春霞。

1范围
本标准规定了金属冲压件的尺寸公差等级、符号、代号、公差数值及极限偏差。
本标准适用于金属板材平冲压件和成形冲压件。
2术语
2.1平冲压件(flatstamping)
经平面冲裁工序加工而成形的冲压件。
2.2成形冲压件(shapingstamping)
经弯曲、拉深及其他成形方法加工而成的冲压件
3公差等级、符号、代号及数值
3.1平冲压件尺寸公差分11个等级。即:ST1至ST11.ST表示平冲压件尺寸公差，公差等级代号用
阿拉伯数字表示。从ST1至ST11等级依次降低。
平冲压件尺寸公差适用于平冲压件，也适用于成形冲压件上经过冲裁工序加工而成的尺寸。
平冲压件尺寸公差数值按表1规定。
