Abstract

Sets out requirements of product performance, safety, design, construction and maintenance, including installation requirements, test conditions and procedures.

Scope

This Standard specifies requirements for the manufacture and testing of skylights comprising a factory-manufactured assembly to permit natural light transmission. The Standard includes requirements for materials, fastenings and hardware, weatherproofing, ventilation, safety labels, marking and maintenance for skylights complete and ready for installation in a roof opening. It is designed for use by manufacturers, suppliers, designers and consumers alike.
This Standard applies to factory-manufactured natural lighting systems installed into roofs including skylights (roof lights), roof windows and tubular skylights (tubular roof lights).
This Standard does not apply to complex overhead roof glazing systems, including barrel vault, atriums, conservatories and roof systems constructed from light-transmitting materials.
NOTES:
1 Alternative methods for determining compliance with this Standard are given in Appendix B.
2 While information on the choice of a skylight for a particular application is outside the scope of this Standard, information is provided in the Commentary C3.2.2 that provides some guidance in this respect.
