It is applicable to double socket couplers provided with elastomeric sealing rings and locking rings and intended for use with PVC-U pressure pipes (see figure 1). The method specifies the internal pressure, the method of calculation for the additional bending force andthe procedureforthebendingtest. 1 PVC-U coupling 2 Sealing ring 3Lockingdevice 4 Solvent cemented PVC-U sleeve 5 PVC-U pipe Figure 1: Example of end-load-bearing double socket coupler 2 Normative reference This Standard incorporates by dated or undated reference, provisions from other publications.
