Organization: ASTM
Publication Date: 1 January 1964
Status: inactive
Page Count: 7
scope:

This method covers the estimation or resistance or vulcanized rubber to cracking when exposed to an atmosphere containing ozone. The rubber specimens are kept under a surface tensile strain, and the ozone concentration in the test chamber is maintained at a fixed value.

The method may not give results correlating exactly with outdoor exposure tests since the correlation of accelerated ozone tests with outdoor performance is in general not good and is, highly dependent upon the specific conditions of both the accelerated and outdoor exposures. Conditions that influence accelerated tests are ozone concentration, relaxation of stress, temperature and degree of bloom or additives. Conditions that influence outdoor tests in addition to these arc the amount of sunshine and rainfall.

NOTE:1-The values Slated in U.S. customary units arc to be regarded as the standard. The metric equivalents of U.S. customary units may be approximate.
