The basis of these provisions is the basic technical welding standards in respect of the special requirements for the construction of railway vehicles.Part 1deals with the basic terms and basic rules,Part 3deals with the design criteria,Part 4deals with the rules for carrying out the work,Part 5deals with quality requirements for weld joints,Part 6deals with the criteria for materials, welding fillers, welding procedures, and the welding planning documents.continued: Page 2 to 27Standards Committee Railway Vehicles (FSF) in the German Institute for Standardisation (DIN)Standards Committee Welding Technology (NAS)DIN 6700-2_06a_2000Englisch_Je.doc1ScopeThis standard applies to the welding of metallic materials during the manufacture and repair of railway vehicles and vehicle parts. It- applies for the division of the parts into classes,- defines the requirements of welding plants,- describes the procedure for the recognition of welding plants,- describes the procedure of conformity assessment.2 Normative referencesDIN EN 287-1Approval testing of welders - Fusion welding -Part 1: SteelDIN EN 287-2Approval testing of welders - Fusion welding -Part 2: Aluminium and aluminium alloysDIN EN 288-2Specification and approval of welding procedures for metallic materials Part 2: Welding procedure specification for arc welding.DIN EN 288-3Specification and approval of welding procedures for metallic materials Part 3: Welding procedure tests for arc welding of steel.DIN EN 288-4Specification and approval of welding procedures for metallic materials Part 4: Welding procedure tests for arc welding of aluminium and its alloys.DIN EN 288-6Specification and approval of welding procedures for metallic materials Part 6: Approval related to previous experience.DIN EN 288-8Specification and approval of welding procedures for metallic materials Part 8: Approval by a pre-production welding test.DIN EN 473Qualification and certification of NDT personnel General principles.DIN EN 719Welding coordination Tasks and responsibility.DIN EN 729-2Quality requirements for welding, Fusion welding of metallic materialsPart 2: Comprehenisve quality requirementsDIN EN 729-3Quality requirements for welding, Fusion welding of metallic materialsPart 2: Standard quality requirementsDIN EN 729-4Quality requirements for welding, Fusion welding of metallic materialsPart 2: Elementary quality requirementsDIN EN 875Destructive tests on welds in metallic materials Impact tests, test specimen location, notch orientation and examination.DIN EN 895Destructive test on welds in metallic materials Transverse tensile testsDIN EN 910Destructive test on welds in metallic materials Bend testsDIN EN 970Non-destructive examination of fusion welds Visual examinationDIN EN 1043-1Destructive test on welds in metallic materials Hardness testing Part 1: Hardness test of arc on arc welded joints.DIN EN 1043-2Destructive test on welds in metallic materials Hardness testing Part 2: Micro hardness testing on welded joints.DIN EN 1418Welding personnel: Approval testing of welding operators for fusion welding and resistance weld setters for fully mechanized and automatic welding of metallic materialsDIN 1910-2Welding: Welding of metals, processes
