GB/T 3672.1-2002 in English

《GB/T 3672.1-2002橡胶制品的公差 第1部分:尺寸公差》由TC35（全国橡胶与橡胶制品标准化技术委员会）归口，TC35SC3（全国橡胶与橡胶制品标准化技术委员会密封制品分会）执行，主管部门为中国石油和化学工业联合会。
本标准对模压、压出和压延的密实橡胶制品规定了尺寸公差级别及公差值，还规定了确定符合本标准所需的相应试验方法。本标准规定的公差适用于硫化胶，也可适用于热塑性橡胶制造的产品。本标准不适用于精密的环形密封圈或胶布之类的压延复合材料产品或用挂胶或贴胶方法涂覆橡胶涂层的产品。

This standard specifies classes of dimensional tolerances, and their values, for molded, extruded and calendered solid rubber products. The relevant test methods necessary for the establishment of compliance with this Standard are also specified.
The tolerances specified in this standard are primarily intended for use with vulcanized rubber but may also be suitable for products made of thermoplastic rubbers.
This standard does not apply to precise toroidal sealing rings or to calendered composite products such as rubber-coated fabrics or products where a rubber coating is applied by the process of topping or skim coating.
