7、BSEN25822:1992 ii BSI 10-1999 National foreword This British Standard has been prepared under the direction of the Welding Standards Policy Committee and is the English language version of EN25822:1991 “Spot welding equipment Taper plug gauges and taper ring gauges”, published by the European Commit
8、tee for Standardization (CEN). Itsupersedes BS4215-4:1990, which is withdrawn. EN 25822:1991 is identical with ISO5822:1988 published by the International Organization for Standardization (ISO). A British Standard does not purport to include all the necessary provisions of a contract. Users of Briti
9、sh Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
