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.
