ASTM D1149 Digital Display Laboratory Ozone Proof Aging Test Chamber

I. Application

Ozone is rare in the atmosphere but a main factor for rubber crack. This product simulates and strengthens the ozone condition in the atmosphere, studies of the law of ozone reacting on rubber, and quickly identifies and evaluates the anti-ozone aging performance and the anti-ozone agent protection efficiency of rubber. Reference standard: GB/T7762-2003 vulcanized rubber or thermoplastic rubber ozone cracking resistance static tensile test, GB/T 2951.21-2008 cable insulation and sheath material general test method, GB/T 11206-2009 rubber aging surface cracking test method, and other relevant standard test methods.

2. Principles and methods

According to the test method and standard, the test method can be divided into "static" and "dynamic". Static means that the sample is stretched and put into the test box for testing. Dynamic means that the sample is placed on the fixture of the test box while stretching, and the fluctuation of stretching is about 5% - 45% of the sample itself.
