- Scope
- This standard classifies porous elastic rubber products, namely sponge and porous rubber. The raw materials used in the manufacture can be natural rubber, reclaimed rubber or synthetic rubber, which can be used alone or in combination. This part of this standard applies only to sheets. 1.2 This standard does not apply to sponge rubber, shoe sole rubber or other similar microporous products, multi-pore hard rubber, original elastic semi-rigid polyurethane sponge rubber or regenerated elastic semi-rigid polyurethane foam rubber, Polyvinyl chloride or recycled polyvinyl chloride or polyvinyl chloride mixed with other polymers. 1.3 The following two types are stipulated: Type 1: open-cell rubber (usually called sponge rubber); Type 2: closed-cell rubber (usually called foam rubber); Classified relative to oil resistance and/or temperature resistance, graded according to a specific range of compression set requirements. Products can further specify additional requirements by adding additional letters after the type, class, and grade. Add numbers after the letters to indicate the test method. 1.4 It should be noted that most of the extruded profiles or molded profiles are too small in size when cutting the standard test pieces. These products are difficult to classify and test by the method specified in this part of this standard, so these steps cannot be used Experiment with it. When there is a conflict between the provisions of this part of this standard and the detailed provisions of special products or the provisions of test methods for specific products, the latter provisions shall be adopted and special instructions shall be given.
