Companies that develop or use the products made of soft elastic materials produce, have usually a laboratory in which the products and raw material are regularly tested according to the standard.
What happens to the hardness property when the product leaves the laboratory and in real use?
HPE III Basic provides significant test data for the material use in laboratory or field
