Abstract / scope
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.
