Method of test for temperature limit of brittleness for vulcanized rubbers
Описание (англ.):
Describes a method for determining the lowest temperature at which rubber compounds do not exhibit brittle failure when impacted under specified conditions. Brittleness temperatures thus determined are not necessarily indicative of service performance. Brittleness temperatures of rubbers are empirical points dependent to alarge degree upon test procedures and apparatus. In order to obtain reproducible brittleness temperature measurements, all pertinent test variables must be thoroughly defined. The procedure outlined here defines those variables.
