It is a combined standard super
12、seding BS 980:1950, BS 1775:1964 and BS 3014:1958 which are withdrawn. In BS 6323, manufacturing processes have been aligned with current procedures, and processes no longer used, i.e. oxy-acetylene welding and hydraulic lap welding, have been deleted. Terminology relating to the designation of cert
