| Resumen: | This document specifies a procedure to qualify a preliminary welding procedure specification (pWPS) by welding procedure tests to produce a qualified welding procedure specification (WPS). This document applies to the following thermoplastic welding processes: hot gas welding: round nozzle, speed, wedge; extrusion welding; heated tool welding: butt, socket, wedge. The document applies to the welding of the following products: sheet, pipe (unreinforced, solid wall only); fittings (unreinforced only); lining membrane. This document covers the welding of the following groups of materials: a) for sheets, pipes and fittings: PVC (including all kinds of PVC-U, PVC-C) and ABS; PP; PE; PVDF; ECTFE, PFA and FEP; b) for lining membranes: PVC-P; PE; ECB;PP; c) for pipes and fittings only: PA-U 11 and PA-U 12 |
