| ANOTACE "ČSN EN 16296 This document specifies quality levels for imperfections in thermoplastics welded joints that have cooled to ambient temperature and is applicable to material thickness above 2,0 mm. Three quality levels are specified 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. The quality level necessary are expected to be defined by the application standard or by the fabricator in conjunction with the user and/or other parties concerned. The level is expected to be prescribed before the start of production, preferably at the enquiry or order stage. This document applies to the following thermoplastic materials : Acrylonitrile-butadiene-styrene plastic, Ethylene-chlorotrifluoroethylene copolymer, Fluorinated ethylene propylene, Unplasticized polyamide, Polybutylene, Polyethylene, Perfluoroalkoxy, Polypropylene block copolymer, Polypropylene homopolymer, Polypropylene random copolymer PVC-C Chlorinated polyvinyl chloride, Unplasticized polyvinyl chloride (rigid PVC), Polyvinylidene fluoride and to the following welding processes: - heated tool welding; - electrofusion socket welding; - hot gas welding using filler rod only; - extrusion welding; - solvent welding of pipes." | ||
