DIN Standards Committee Elastomer Technology

Overview

This European Standard specifies the materials and dimensions for metal banded flexible couplings and adaptors and bushes for use with pipes and fittings in drain and sewer systems, usually operated under gravity and periodic hydraulic surcharge, both above and below ground inside or outside buildings and intended to connect pipes for: repair of damaged pipelines; connecting pipes of different materials and/or diameters; jointing short/cut lengths of pipe; jointing specific pipe systems; jointing post-inserted preformed junctions. The coupling consists of a moulded or extruded rubber sleeve with two stainless steel clamping bands with or without a stainless steel shear band. The clamping bands enable the sleeve to form a seal with the pipes to be joined. The shear band gives resistance to shear forces. Connections may be made between pipes which cannot be satisfactorily joined by a coupling alone, of dissimilar sizes or material, by using an appropriate bush or bushes with the coupling or by using an appropriate adaptor. The German committee responsible for this standard is NA 119-05-09 AA "Allgemeine Anforderungen an Rohre, Rohrverbindungen etcetera für Abwasserkanäle und -leitungen (CEN/TC 165/WG 1 und CEN/TC 165/WG 1/TG 1)" ("General requirements for pipes, pipe connections, etcetera used in drains and sewers (CEN/TC 165/WG 1 and CEN/TC 165/WG 1/TG 1)") at DIN.
