LR-B014 Ventilation Aging Chamber

Use

The hot air aging test box is suitable for the heat resistance test of electrical insulation materials, the air exchange aging test of electronic spare parts, plasticized products, etc.The adaptability of the sample to storage and use in high temperature environment was evaluated and judged. The performance of the sample after aging in air under simulated high temperature and atmospheric pressure was measured and compared with the performance of the non-aging sample.

Test standard:In accordance with the standard GB/ t3512-2014 /ISO 188 2011 “vulcanized rubber or thermoplastic rubber/hot air accelerated aging and heat resistance test” turbulence design.
