GB/T 12385-2008 Translated English of Chinese Standard. (GBT 12385-2008, GB/T12385-2008, GBT12385-2008): Standard test method for sealability of gaskets for pipe flangesThis Standard specifies 2 test methods, Method A and Method B, for the sealability of gaskets for pipe flanges. The 2 test methods of this Standard are applicable to asbestos rubber gaskets, non-asbestos rubber gaskets, rubber gaskets, Teflon gaskets, expanded or modified Teflon gasket, flexible graphite composite gaskets, spiral wound gaskets, metallic clad gaskets, Teflon clad gaskets and gaskets of serrated metal, corrugated metal and waveform serrated metal with non-metallic coating. They are also applicable to metallic flat gaskets. |
