Introduction: It is used to evaluate the aging degree of rubber in ozone environment. It can be used in rubber seals, wire and cable insulation sheaths, tires, hoses and other rubber products exposed to a sealed, constant temperature and no light in ozone environment, and then subjected to static stretching and dynamic stretching. After deformation, the degree of change in the degree of cracking of the sample and other physical properties was examined to assess the aging resistance of rubber resistant to ozone to meet the criteria: ASTM-D1149 ASTM-D3395 GB/T2951-1997 GB/T7762-2003 GB/T13642-1992 SAEJ1401 Technical Parameters: Temperature control range: 0～60°C (adjustable) Temperature fluctuation: ≤±0.5°C Temperature uniformity: ≤±2°C Humidity control range: ≤ 65% R.H (relative humidity) Ozone concentration control range: 10 ~ 1000pphm (direct reading, maximum deviation of 10%) Ozone gas flow control: 0 ~ 100L/min Time control range: 1min to 9999hours (arbitrary setting) Sample rack rotation speed: 1～10r/min (adjustable) Sample tensile speed: up to 20 times per minute; manual stretching distance, dynamic stretching, static stretching, human operation Test chamber inner shell material: SUS304 stainless steel Sample rack and stretching device material: 316L stainless steel material
