Резина. Определение сопротивления разрыву. (Угловые, серповидные и надрезанные образцы для испытаний)
Название (англ.):
Rubber, vulcanized; Determination of tear strength (trouser, angle and crescent test pieces)
Описание (англ.):
Specifies three test methods for the determination of the tear strength of vulcanized rubber, namely: Method A, based on the use of a trouser test piece; Method B, based on the use of an angle test piece, with or without a nick of specified depth; Method C, based on the use of a crescent test piece. The value of tear strength obtained depends on the shapeof the test piece, speed of stretching and temperature of test. It may also be susceptible to grain effects in vulcanized rubber.
