ISO 3302-1:2014规定了模制、挤压和压延实心橡胶产品的尺寸公差等级及其值。还规定了确定符合ISO 3302-1:2014所需的相关试验方法。 公差主要用于硫化橡胶，但也适用于热塑性橡胶制成的产品。 ISO 3302-1:2014不适用于精密环形密封圈或压延复合材料产品，如橡胶涂层织物或通过顶涂或脱脂涂层工艺涂覆橡胶涂层的产品。

ISO 3302-1:2014 specifies classes of dimensional tolerances and their values for moulded, extruded, and calendared solid rubber products. The relevant test methods necessary for the establishment of compliance with ISO 3302-1:2014 are also specified. The tolerances are primarily intended for use with vulcanized rubber but can also be suitable for products made of thermoplastic rubbers. ISO 3302-1:2014 does not apply to precision toroidal sealing rings or to calendared composite products such as rubber-coated fabrics or products where a rubber coating is applied by the process of topping or skim coating.
