scope:

This standard sets the performance requirements for heat and smoke vents under simulated laboratory conditions. This standard sets their performance requirements when exposed to various natural hazards such as simulated wind loading, the impact of simulated hail and the possible degradation effects of sunlight. The standard also examines their ability to withstand the impact effects of temporary live loads as well as to be able to operate under anticipated roof live (snow) loads. Finally, the standard validates the temperature the heat and smoke vent will operate as reported by the manufacturer.

This standard is not intended to be used to determine when or where heat and smoke vents are to be used or how to determine the amount of vented area needed.

This standard is not intended to qualify skylights.

This standard is intended to evaluate only those hazards investigated and is not intended to determine suitability for the end use of the product.

The results of tests conducted under the controlled conditions required by this standard shall not be used to describe or appraise performance under actual fire or natural hazard conditions as actual fire and natural hazard conditions vary widely.

This standard does not examine the product's solar optical values such as transmittance, reflectance or absorbance or other properties such as air leakage, water leakage, solar radiation, insulating properties or other properties related to the resistance of heat flow through the product due to indoor and outdoor temperature differentials.

Purpose

This standard states testing and certification requirements for heat and smoke vents.

Testing and certification criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance program.
