Four procedures are given:

The compressive properties of rubber are tested using compression platens. Sandpaper may be used in between the platens and the sample in order to reduce the occurance of slippage. For this test, the rubber sample is compressed to a pre-specified deflection percentage. Standard Test Methods for Rubber Properties in Compression or Shear (Mechanical Oscillograph) 1. Scope 1.1 These test methods cover the use of the Yerzley mechanical oscillograph for measuring mechanical properties of rubber vulcanizates in the generally small range of deformation that. Specific test procedures depend upon the shape of each component and the type and direction of bonding. The most common test methods are a butt test, cone test and peel test.
