This Supplement to BS 499-1:1991 has been prepared under the direction of theWelding Standards Policy Committee. It implements IEV 50 (851),i.e. Chapter 851: Electric Welding of the International Electrotechnical
Vocabulary,published by the International Electrotechnical Commission (IEC).It is published, at present, as a Supplement to BS 499-1:1991, as this standard isnot due to be revised in the near future. When revision does take place, the termsand definitions in the Supplement will be incorporated in the text of the maindocument and duplication will be eliminated.

A British Standard does not purport to include all the necessary provisions of acontract. Users of British Standards are responsible for their correct application.
