The Standard includes requirements for materials, fastenings and hardware, weatherproofing, ventilation, safety labels, marking and maintenance for rooflights complete and ready for installation in a roof opening. It is designed for use by manufacturers, suppliers, designers and consumers.This Standard applies to factory-manufactured natural lighting systems installed into roofs including skylights, roof windows and tubular skylights (also known as tubular daylighting devices).This Standard does not apply to overhead roof glazing systems, including barrel vault, atriums, conservatories and roof systems constructed from light-transmitting materials.NOTE While information on the choice of a rooflight for a particular application is outside the scope of this Standard, some guidance in this respect is provided in Appendix B.
