ISO 6944 (1985) was adopted as the test conventional for fire-rated ducting - this was renamed British Regular 476 Component 24 (1987) and it has considering the fact that been the principle take a look at conventional for ducting. The purpose of this regular is to evaluate the power of the ductwork system to resist the distribute of fire from one particular fire compartment to a different without the help of fire dampers. It ought to be famous the examination standard relates to a complete ductwork installation - including joints and supports - and worries its security, insulation and integrity. The testing regular also differentiates between two kinds of fire exposure. Type A is in which ductwork resists penetration of fire from exterior a duct. Type B is in which ductwork resists penetration of fire from inside a duct. Ductwork devices that don't Usually incorporate fire dampers are: Smoke extract ducts Pressurisation ducts Automobile park extract ducts Kitchen extract ducts A common rule, however, is usually that any ductwork process that is intended to function, or incorporates a Distinctive use, below a fire situation and for that reason simply cannot use fire dampers, would require a fire resistance score. Therefore the ductwork by itself must offer exactly the same levels of fire resistance as that provided by the compartment wall or flooring, to limit the spread of fire. Considerable variations The ductwork sector faces sizeable alterations through the subsequent number of years, as The existing exam standards are now being replaced by harmonised European requirements. The important date for transform is July 1 2011, when the Construction Products Directive will become a statutory necessity and BS476 Aspect 24 (1987) will likely be withdrawn and also the BS EN 12101 sequence Products Building Benchmarks will choose precedence.
