DIN CEN/TS 14632:2024-04

This document gives guidance on the assessment of conformity of GRP-UP (glass-reinforced thermosetting resins based on unsaturated polyesters) piping products and assemblies in accordance with EN ISO 23856, ISO 25780 and ISO 16611 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of third-party certification procedures. This document also gives guidance on the assessment of conformity of GRP-UP manholes and inspection chambers (see EN 15383 for additional information). Pipes (see EN ISO 23856) are used for manufacturing the shafts and chamber units. For the purposes of this document, the term polyester resin (UP) also includes vinyl ester resins (VE). CEN/TS 14632:2023 has been prepared by Technical Committee CEN/TC 155 "Plastics piping systems and ducting systems", the secretariat of which is held by NEN (Netherlands). The responsible national standardization committee is NA 119-05-43 GA "Gemeinschaftsarbeitsausschuss NAW/FNK: Rohrleitungssysteme aus GFK (CEN/TC 155/WG 14)" ("Joint working committee NAW/FNK: Pipe systems of glass-reinforced thermosetting plastics") at DIN Standards Committee Water Practice (NAW).
