This part of is 3302 specifies the following geometric tolerances for molded or extruded solid rubber products, including those with metal inserts:
——flatness tolerance;
——parallelis tolerance;
——perpendicularity tolerance;
——tolerance coaxiality;
——position tolerance. The tolerances were initially intended for use with vulcanized rubber but can also be suitable for products made from thermoplastic rubbers.
