ISO 34-1 is a testing standard for measuring the tear strength of vulcanized or thermoplastic rubbers. This standard describes three different test methods based on specimen geometry as the value of tear strength obtained depends on the shape of the test specimen in addition to the testing speed and temperature. Method A outlines the test procedure using a trouser test piece, method B using an angle test piece, and method C using a crescent test piece.
