DIN EN 13067:2013-01EN 13067:2012 (E) 4 Introduction This standard covers the principles to be obser
23、ved in the qualification testing of welder performance for the welding of thermoplastic materials. The ability of the welder to follow verbal or written instructions and testing of his skill are important factors in ensuring the quality of the welded product. This standard is intended to provide the
24、 basis for the mutual recognition by examining bodies for qualification relating to welders competence in the various fields of application. DIN EN 13067:2013-01EN 13067:2012 (E) 5 1 Scope This European Standard specifies the method of testing the knowledge and skill of a welder who is required to c
25、arry out welds on thermoplastics in new constructions and repair work. The skill examination of a welder is an essential condition for the assurance of the quality of the welding work. The application of this standard guarantees that the examination is carried out according to a uniform test procedu
26、re. This European Standard applies when the contractor or the authorities responsible for the application require it. Gas and water utility network industries with alternative qualification programmes are excluded from this standard. This European Standard applies to the following welding processes:
27、 hot gas welding: round nozzle, high speed nozzle, wedge; extrusion welding; heated tool welding: butt, saddle, socket, wedge; electrofusion welding: socket, saddle; solvent welding: socket. This European Standard applies to the welding of the following products: sheet; pipe; fittings; lining membra
28、ne. This European Standard covers the welding of the following groups of materials: a) for sheets, pipes and fittings: 1) group 1: PVC (including all kinds of PVC-U, PVC-C), ABS; 2) group 2: PP (including all kinds of PP); 3) group 3: PE (including all kinds of PE); 4) group 4: PVDF; 5) group 5: ECT
29、FE or PFA or FEP; b) for lining membranes: 1) group 6: PVC-P; DIN EN 13067:2013-01EN 13067:2012 (E) 6 2) group 7: PE (including all kinds of PE); 3) group 8: ECB; 4) group 9: PP. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are
