Product Features:
The inner liner adopts a double-layer circular arc design, which can prevent the phenomenon of condensation and dripping during the test, thereby avoiding the direct impact of superheated steam on the test results of the product during the test process.
The product meets the JESD22-A100 to A118 bias voltage (BHAST) or non bias voltage (UHAST) accelerated moisture resistance test and saturated high-pressure steam (cooking) test.
◎ The product is compatible with high acceleration temperature and humidity stress HAST aging test and high-pressure cookingPCTMoisture resistance test.
