Ozone content in the atmosphere is very small, but it is a major factor of rubber cracking.
Ozone aging test chamber is designed to research the effect rule of ozone on rubber, identify and evaluate the method of rubber anti-ozone aging performance and anti-ozone agent protection efficiency by simulates and intensifies ozone conditions in the atmosphere.
GB/T7762-2003 Test method for static tensile resistance of vulcanized or thermoplastic rubber to ozone cracking
GB/T2951.21-2008 General test method for cable insulation and sheath materials,
GB/T 11206-2009 Rubber aging test surface cracking method, and test methods specified in other relevant standards.
4. The principle and method:
Ozone Aging Test can be divided into STATIC and DYNAMIC according to different test method and standards. Default configuration is static test method.
STATIC means that specimen will be stretched before putting into the test chamber.
DYNAMIC means fixing the specimen on the fixtures inside testing chamber, and stretch it while testing. The stretching rate is about 5%-45% of the specimen.
