About This Item

 

Full Description

BS 7668:2016 specifies the technical delivery requirements for weldable weather resistant hot finished seamless, electric welded and submerged arc welded (longitudinal or helical) steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot with or without subsequent heat treatment, or formed cold with a subsequent full body heat treatment to obtain equivalent metallurgical conditions to those obtained in a hot formed product.

The products are equally suitable for welded, bolted and riveted structures. The hollow sections specified in this British Standard are intended for use in construction or for general engineering purposes. Requirements for tolerances, dimensions and sectional properties are specified in BS EN 10210-2.

NOTE Four material grades are specified in this standard and the user should select the grade appropriate to the intended use and service conditions.


This British Standard does not apply to products currently covered by, BS EN 10210-1, BS EN 10219-1, BS EN 10219-2 or BS EN 10225. However, the grades in BS 7668:2016 are compatible with those of similar strength level specified in BS EN 10025-5.

In addition to the definitive requirements, this standard also requires the items detailed in Clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items are to be satisfied.
