ActiveEnvironmental testing―Part 2: Test methods―Test Cx: Damp heat, steady state (unsaturated pressurized vapour)
环境试验 第2部分：试验方法 试验Cx：未饱和高压蒸汽恒定湿热
Application Summary AI generated
This standard specifies a damp heat test method using unsaturated pressurized steam to evaluate the resistance of electronic components, electrical equipment, and materials to moisture penetration and corrosion under high temperature and humidity conditions. It is applied in industries such as aerospace, automotive electronics, and telecommunications for product reliability testing, particularly for components sealed in enclosures or subjected to condensation-prone environments. The test simulates accelerated aging in tropical or humid climates to verify insulation integrity and functional performance during storage or operation.
