This is the third edition of CSA A660, Certification of manufacturers of steel building systems. It supersedes the previous editions, published in 2004 and 1991.
This Standard applies to the certification of manufacturers of steel building systems.
This Standard prescribes the procedure for certification based on an audit of a manufacturer's plants and facilities by the certification body.
This Standard provides the requirements for a certificate of design and manufacturing conformance for each steel building system supplied by a certified manufacturer (see Clause 12). Note: This should not be construed as third-party certification of the steel building system.
Inspection of the structure in its final erected state is outside the scope of this Standard.
Note: Inspection and approval requirements are under the jurisdiction of applicable building authorities.
