High acceptation for Ozone-Resistance-Tests by rubber-containing specimen! Embrittlement by the use of Ozone-admission. Beginning with fissures, proceeding destruction of the specimen.
The ozone measuring and control system continuously takes samples of gas volume and automatically corrects (closed control circuit) any losses/fluctuations of the O3 concentration. The ozone is produced locally, because of the very short decay time (ca. 30 min).
