Foreword

Publishing information

This part of BS 499 is published by BSI and came into effect on 31 December 2008. It was prepared by Technical Committee WEE/1, Definition and symbols for welding. A list of organizations represented on this committee can be obtained on request to its secretary.

Supersession

This part of BS 499 supersedes BS 499‑1:1991, which is withdrawn.

Relationship with other publications

This standard has been aligned, as far is as practicable, with existing European 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 standards that have not been adopted as British Standards. Where it was felt that an existing definition needed clarification, this has been done while striving to not contradict the existing definition. As far as practicable, the numbering system used in this standard follows that of BS EN 1792:2003 with new numbers allocated to terms that are not in the European standard.

Where definitions are based on those in a European or international standard, the identifier of the original standard is given in square brackets after the definition.

BS 499 is published in two parts, with a supplement to this part:

Part 1: Glossary for welding, brazing and thermal cutting
Part 1, Supplement: Definitions for electric welding equipment
Part 2c: European arc welding symbols in chart form
NOTE 1 BS 499‑1, Supplement is a reproduction of IEV 50 (851):1991
NOTE 2 BS 499‑2c is based on BS EN 22553.

Contractual and legal considerations

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.
