What is BS 476-31.1 - Smoke penetration under ambient temperature conditions about?
BS 476-31.1 is the 31.1st part of the multiple series that focuses on the fire tests on building materials and structures.
BS 476-31.1 describes a method for measuring smoke penetration, as represented by the measurement of air leakage rate, through door sets and vertically oriented shutter assemblies under ambient temperature conditions.
Who is BS 476-31.1 - Smoke penetration under ambient temperature conditions for?
BS 476-31.1 on smoke penetration under ambient temperature conditions is useful for:
- Architects
- Civil engineers
- Construction industries
- Real estate developers
- Interior designers
Why should you use BS 476-31.1 - Smoke penetration under ambient temperature conditions?
When smoke and gases from a fire start to spread in a building, a pressure difference can develop between the two sides of a closed doorset or shutter assembly. Leakage of smoke can occur through the clearances between the door leaf and the frame and other openings.
BS 476-31.1 specifies the performance of doorsets and shutter assemblies to the penetration of smoke and gaseous products from fires under ambient temperature conditions. BS 476-31.1 specifies a method that simulates the conditions to which doorsets and shutter assemblies will help you in practice during either the very early stages of fire development or at positions remote from the seat of the fire. Further methods are under consideration that describes procedures that will help you for evaluating the performance of doorsets and shutter assemblies at medium and high temperatures.
Overall, BS 476-31.1 will help you to evaluate the performance of a fire door used for smoke control.
