This European Standard provides quality levels for imperfections in thermoplastics welded joints. It applies to material thickness above 2,0 mm.Three quality levels are given in order to permit application for a wide range of welded fabrication. They are designated by symbols B, C and D, where B is the most stringent. The quality levels refer to production quality and not to the fitness-for-purpose (see 3.2) of the manufactured product.This European Standard applies to the following thermoplastic materials:Table 1AbbreviationMaterial descriptionABSAcrylonitrile-butadiene-styrene plasticECTFEEthylene-chlorotrifluoroethylene copolymerFEPFluorinated ethylene propylenePBPolybutylenePEPolyethylene PFAPerfluoroalkoxyPP-BPolypropylene block copolymerPP-HPolypropylene homopolymerPP-RPolypropylene random copolymerPVC-CChlorinated polyvinyl chloridePVC-UUnplasticised polyvinyl chloride (rigid PVC)PVDFPolyvinylidene fluorideand to the following welding processes:- Heated tool welding;- Electrofusion welding;- Hot gas welding using filler rod only;- Extrusion welding;- Solvent welding of pipes.
