33、ember 2008. It was prepared by Technical Committee WEE/1,Definition and symbols for welding. A list of organizationsrepresented on this committee can be obtained on request to itssecretary.SupersessionThis part of BS 499 supersedes BS 499-1:1991, which is withdrawn.Relationship with other publicatio

34、nsThis standard has been aligned, as far is as practicable, with existingEuropean and international lists of terms and definitions for welding,including BS EN 1792:2003, PD CEN/TR 14599, BS ISO 857 (all parts)and BS EN 13622. There might not be full agreement with standardsthat have not been adopted

35、 as British Standards. Where it was feltthat an existing definition needed clarification, this has been donewhile striving to not contradict the existing definition. As far aspracticable, the numbering system used in this standard follows thatof BS EN 1792:2003 with new numbers allocated to terms th

36、at are notin the European standard.Where definitions are based on those in a European or internationalstandard, the identifier of the original standard is given in squarebrackets after the definition.BS 499 is published in two parts, with a supplement to this part:*Part 1: Glossary for welding, braz
