For the special test instruments such as the ozone aging test box, it is necessary to meet the clearly specified test standards. The following lists the experimental standards (QQ)
1, GB/T7762-2003 vulcanized rubber or thermoplastic rubber resistance to ozone cracking static tensile test method 2, GB/T2951.21-2008 cable insulation and sheathing material general test method Ozone aging test chamber related standards specified test methods outlined 1. Brief description of the ozone aging test box GB/T7762-2003 standard:
Standard Name: Vulcanized Rubber or Thermoplastic Rubber Resistant to Ozone Cracking Static Tensile Test This standard specifies the environment in which vulcanized rubber or thermoplastic rubber is directly affected by air under a certain concentration of ozone under static tensile strain conditions and at a prescribed temperature with no light. Ozone cracking resistance test method. This standard is a revision of GB/T7762-1987.
2. Brief description of the ozone aging test box GB/T2951.21-2008:
GB/T 2951 prescribes test methods for power distribution and communication cables and optical cables, including polymer insulation and jacket materials for ships and offshore cables and optical cables, and specifies the ozone resistance test method, heat extension test method, and dip mineral oil test. method. Elastomer mixes for wire, cable and fiber optic cable.
"GB/T2951.21-2008 General test methods for insulating and sheathing materials of cables and optical cables - Part 21: Specific test methods for elastomer mixtures - Ozone resistance test - Hot elongation test - Test for dipping mineral oil" Reader: Cables And optical cable research, production, use, testing technicians.
3, in addition to the above-mentioned GB/T7762-2003 vulcanized rubber or thermoplastic rubber resistance to static cracking test method of ozone cracking, GB/T2951.21-2008 cable insulation and sheathing material general test method, ozone aging test box is also in line with other The test methods specified in the relevant standards are standard.

Brief description of test standards and test methods to be met by ozone aging test box
Ozone aging test box () can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheath and other products, under static tension and deformation, in the sealed non-light containing constant ozone concentration of air and constant temperature test chamber, press Specimens are tested at predetermined times, and the degree of cracking or other property changes that occur on the surface of the specimen is used to assess the resistance to ozone aging of the rubber.
