DIN EN 681-2-2006 弹性体密封件.给排水用管道连接密封件的材料要求.第2部分:热塑性弹体(包括修改件A1-2002 + A2-2005)
Elastomeric seals - Material requirements for pipe joint seals used in water and drainage applications - Part 2: Thermoplastic elastomers (includes Amendments A1:2002 + A2:2005); English version of DIN EN 681-2:2006-11
This standard specifies requirements for materials used for moulded seals only of thermoplastic elastomers (TPE) used in joints of:
1) thermoplastic piping systems for non pressure waste water discharge (intermittent flow up to 95℃) inside buildings;
2) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow up to 45℃ and intermittent flow up to 95℃);
3) thermoplastic rainwater piping systems.
General requirements for finished joint seals are slso given; any additional requirements called for by the particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design.
