《GB/T 7993-2003用在腐蚀条件下的搪玻璃设备的高电压试验方法》由TC72(全国搪玻璃设备标准化技术委员会)归口,主管部门为中国石油和化学工业联合会。
本标准规定了用在腐蚀条件下的搪玻璃设备的高电压试验方法。高电压试验的目的在于检测和定位搪玻璃层中延伸至金属基体的缺陷和搪玻璃层中的薄弱点。


Scope

This standard specifies the high voltage test method for glass-lined equipment used in corrosive conditions. The purpose of the high voltage test is to detect and locate defects in the glass-lined layer extending to the metal substrate and weak points in the glass-lined layer. This test method is applicable to the detection where the voltage is not lower than 2 kV and the thickness of the glass-lined layer is not less than 660 μm.
