Circular specimens are subjected to rubbing motion against an abradant MD at a defined pressure 9 kilopascal or 12 kilopascal. After washing and drying, the specimens are again measured and used to calculate dimensional change between the starting and finishing measurements in per cent. Firstthe original length and width dimensions are measured, after which the samples are washed and dried according to the specifications. We ensure that uvex products actually exceed the necessary safety criteria by conducting extensive tests on the material.

In both cases, ten specimens five weft and five warp are prepared for the test and cut to size as per the respective norm specifications, creating either a piece that resembles a pair of trouser legs or a trapezoid specimen. This test measures the force that is required to propagate a cut, in other words the tear growth. Amazon Prime Music Stream millions of songs, ad-free.
