Compliance

The design and construction should ensure that all fixtures and fittings chosen for the project should meet the requirements of the referenced standards. For the most part, the major manufacturers should be able to supply products meeting these standards as a matter of course. However, the team should maintain product cut sheets and information for the code official to review to prove compliance with this requirement.
