For determining the resistance of elastomers (rubber products) to cracking under ozone exposure, national and international standards apply. Ozone test cabinets have been designed hitherto in accordance with DIN 53509.

Recommended devices in accordance with DIN ISO 1431-1, with test tools for static and dynamic aging tests:
