This European Standard specifies methods for assessing the tin coating on drawn round copper wire for the manufacture of electrical conductors, e.g. according to EN 13602. This European Standard includes test methods for the determination of the following characteristics: a) thickness of the unalloyed tin coating; b) continuity of the tin coating; c) adherence of the tin coating. WARNING - This European Standard can involve the use of hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with their use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This part of EN 746 specifies the safety requirements for combustion and fuel handling systems that are part of industrial furnaces and associated processing equipment (TPE). NOTE The general safety requirements common to TPE are provided in prEN 746 1:2020 (See introduction). This part of EN 746 deals with significant hazards, hazardous situations and events relevant to combustion and fuel handling systems as listed in Annex A, when used as intended and under the conditions foreseen by the manufacturer. This part of EN 746 covers: - fuel pipework downstream of and including the manual isolating valve; - combustion air supply (including oxygen and oxygen enriched combustion air) and flue gas system; - burner(s), burner system and ignition device; - functional requirements for safety related control system. This part of EN 746 applies to any oxidation with air or other gases containing free oxygen of gaseous and liquid fuels or any combustion of them to release thermal energy in TPE. For thermal or catalytic post combustion and waste incineration, this part of EN 746 applies only to auxiliary burners designed to start-up and/or support the process. The pressure hazard of the piping and components covered by this part of EN 746 is within the maximum pressure/size relationship of category I as described in normative Annex E. This part of EN 746 also gives the necessary requirements regarding information for use. This part of EN 746 does not cover hazards from heating generated by electricity. This part of EN 746 does not deal with the hazards created by the release of flammable substances from the products processed in the TPE. This part of EN 746 is not applicable to combustion and fuel handling systems: - of gas welding and allied processes; - up-stream of the TPE manual isolating valve. This part of EN 746 is not applicable to electrical cabling and power cabling upstream of the TPE control panel/protective system.

This document 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 document applies to the following thermoplastic materials in Table 1: Table 1 - Thermoplastic materials Abbreviation Material description ABS Acrylonitrile-butadiene-styrene plastic ECTFE Ethylene-chlorotrifluoroethylene copolymer FEP Fluorinated ethylene propylene PA-U Unplasticized Polyamide PB Polybutylene PE Polyethylene PFA Perfluoroalkoxy PP-B Polypropylene block copolymer PP-H Polypropylene homopolymer PP-R Polypropylene random copolymer PVC-C Chlorinated polyvinyl chloride PVC-U Unplasticised polyvinyl chloride (rigid PVC) PVDF Polyvinylidene fluoride and to the following welding processes: - heated tool welding; - electrofusion welding; - hot gas welding using filler rod only; - extrusion welding; - solvent welding of pipes.
