本文件规定了塑料模制零件的可能制造公差。 本文件规定了所有具有一般公差的整体特征，以及规定基准系统内的表面轮廓公差。它允许在功能需求和要求的情况下，使用ISO GPS工具进行尺寸和几何公差的附加规范。 本文件涉及热塑性塑料、热塑性弹性体和热固性热塑性塑料制成的无孔模塑件的注射成型、注射压缩成型、转移成型、压缩成型和旋转成型。如果合同双方同意，本文件适用于其他塑料工艺。 本文件未提及模制零件表面缺陷，如凹陷痕迹、不希望出现的流动结构和粗糙度，以及接合线。 本文件无意取代、替换或以任何方式干扰产品标准中的公差要求。

This document specifies possible manufacturing tolerances for plastic moulded parts. This document specifies all integral features with general tolerances with surface profile tolerance within a specified datum system. It allows for additional specifications in case of functional needs and requirements using the ISO-GPS-tools for dimensional and geometrical tolerating. This document addresses injection moulding, injection compression moulding, transfer moulding, compression moulding and rotational moulding of non-porous moulded parts made from thermoplastics, thermoplastic elastomers and thermosets of thermoplastics. This document is applicable to other plastic processes if agreed to by the contractual parties. Moulded part surface imperfections such as sink marks, undesired flow structures and roughness, as well as joint lines are not addressed in this document. This document is not intended to supplant, replace or in any way interfere with requirements for tolerances found in product standards.
