Requirements for automatic flash welding of ferrous metal sections, excluding tubes, pipes and pipe fittings for pressure applications (covered in BS 4204).

This British Standard specifies requirements for the automatic flash welding of ferrous metal sections excluding tubes, pipes and pipe fittings for pressure applications, which are covered in BS 4204.

In addition to the definitive requirements, it also requires the items detailed in clause 3 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
