The above are generally classified as compliance to specifications, quality control, and research and development. Specifications are requirement for an end product. Control tests are conducted by rubber product manufacturers and research and development tests are conducted for acquiring more information about processes, products, applications development and raw materials. The physical testing of rubbers often involves application of a force to a specimen of rubber and measurement of the resultant deformation or conversely application of a deformation and measurement of the required force.

Physical testing of rubbers is the concern of PRI/22 which has a panel to deal with electrical tests. Until recently, there were 4 other active panels to split the detailed work on test methods but, as a result of the drive to economise effort and the effects of virtually all test methods coming from ISO, they were disbanded. Other committees which should be mentioned in the context of testing are PRI/71 which deals with flexible cellular materials, PRI/20 for accuracy of test machines, PRI 26 for burning behaviour of plastics and rubber and PRI/23 for chemical testing. Unfortunately, systems are never as simple as we would like specialised tests may be considered in product committees and not all products containing rubber are covered in PRI committees...
