BS EN ISO 15614-1:2017 Incorporating Corrigendum July 2017 BSI Standards Publication Specification and qualification o f welding procedures for metallic materials — Welding procedure test Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys BS EN ISO 15614-1:2017 BRITISH STANDARD National foreword This British Standard is the UK implementation of EN ISO 15614-1:2017. It supersedes BS EN ISO 15614-1:2004+A2:2012, which is withdrawn. BSI, as a member of CEN, is obliged to publish EN 15614-1:2017 as a British Standard. However, attention is drawn to the fact that during the development of this standard, the UK committee voted against its approval. The UK committee is concerned that the format of this standard may cause a problem when working to either of the two welding procedure test levels. Level 1 is based on the requirements of ASME BPVC Section IX, , and Level 2, for which the extent of testing is greater, is based on the previous version of this standard; BS EN ISO 15614-1:2004+A2:2012. It is important to note Welding, Brazing, and Fusing Qualifications that a procedure test carried out to Level 2 automatically qualifies for Level 1 requirements, but not vice-versa. Furthermore, when no level is specified in a contract or application standard, all the requirements o f Level 2 should be applied. Users should be aware that, as the requirements of the two levels are o ften specified in the same clause, vigilance is required to identi fy the testing requirements and the range o f qualification for the particular welding procedure test level. The UK participation in its preparation was entrusted to Technical Committee WEE/3 6, Qualification o f welding personnel and welding procedures. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. © The British Standards Institution 2017 Published by BSI Standards Limited 2017 ISBN 978 0 580 51032 8 ICS 25.160.10 Compliance with a British Standard cannot con fer immunity from legal obligations.

For process 111, alternating current also quali fies direct current (both polarities) unless impact testing is required. 8.4.7 Heat input (arc energy) The heat input can be replaced by arc energy (J/mm). The arc energy shall be calculated in accordance with ISO/TR 18491. When using the calculation for the heat input, the k-factor according to ISO/TR 17671-1 shall be considered. The kind of calculation, either heat input or arc energy, shall be do c u me n te d .

For process 111, the heat input may also be measured by the run out length per unit length of electrode. When the welding time is too short and when the length of the weld is not signi ficant (e.g. for small repair, for tack welds), the heat input need not to be veri fied; only the adjustable parameters should be checked like amperage and/or voltage. Arc energy and heat input are measures of the heat generated by the arc. Whereas, in the past, these were different terms for the same measure, they are now calculated in different ways. Either arc energy or heat input may be used for welding control, calculated in accordance with ISO/TR 18491. 8.4.8 Preheat temperature A de c re a s e o f mo re th a n 5 0 °C fro m the re c o rde d p re he ati n g te mp e ratu re o n the WP QR re qu i re s a re - quali fication.
