Usage

The hot air aging test chamber is suitable for conducting thermal resistance tests on electrical insulation materials, as well as aging tests for electronic components, plastic products, and other items; it is used to evaluate and determine the adaptability of these materials in storage and use under high-temperature conditions. The samples are aged in simulated high-temperature and atmospheric pressure air, and their properties are measured and compared with those of the un-aged samples.

Test standards

It conforms to the turbulent flow design specified in the standard ASTM D5721/GB/T3512-2014/ISO 188 2011 "Sulfurized rubber or thermoplastic rubber / Accelerated aging and heat resistance test under hot air conditions".
