Test on specially moulded test piece

The test piece shall be moulded by the manufacturer with identical compound and under identical vulcanizing conditions as used in manufacture of the bearings. The test pieces should be suitably identified and certified. The test pieces will be subjected to the following tests:

  • Test for chemical composition, specific gravity,ash content etc.
  • Test for physical properties such as

(i) Hardness

(ii) Ultimate tensile strength

(iii) Elongation at break

(iv) Accelerated aging test

(v) Compression set test

(vi) Ozone test
