JB/T 1712-2008Valve components - Packings and packing washers (English PDF)

JB/T 1712-2008 is the English-translated version of 阀门零部件 填料和填料垫.

Packing for valves is the subject of JB/T 1712-2008, a recommended Chinese machinery industry standard. It specifies the structure, the size and the technical requirements of flexible graphite packing, plastic packing and the packing cushion, and the application it states is flexible graphite packing and plastic packing. Four earlier documents are listed as superseded: JB/T 1712-1991, JB/T 1713-1991, JB/T 1716-1991 and JB/T 5209-1991. Among the standards it quotes are GB/T 700-2006, GB/T 1220-2007, GB/T 12226-2005 and JB/T 6617-1993. The catalogue gives Chinese classification J16 and ICS 23.060, and names the Ministry of Industry and Information Technology as the issuing agency.
