Specification for Airbricks and gratings for wall ventilation

BS 493-1995+A1-2010 发布历史

This British Standard specifies requirements for two classes of wall ventilating units as follows: class 1:airbricks for useinexternal walls; class 2: wall ventilators or gratings for internal use. Some typicalexamples of designs are shown in Figure 1,Figure 2 and Figure 3. Other patterns may however be supplied, provided they conform to the requirements of this standard. Guidanceon the information to be supplied by the purchaser when ordering is given in Annex A. Thisstandard contains no requirements for the following properties. Durability (other t hanresistance t o colour change of thermoplastics materials). It is recommended that where there is uncertainty about durability then expert advice should be sought. a) Fire properties s o tf hermoplastics materials. The general useof thermoplastics airbricks, wall ventilators and gratings in isolation in masonry is considered t ohave aninsignificant effect on t he spreadoffire.However, special consideration should begiven to the useof thermoplastics air bricks where it is intended togroup a number of them together, e.g. for boiler house ventilation. b) Compressive strengthof thermoplastics air bricks. The general useof theseinisolation is considered tohave tohave aninsignificant effect on masonry strength. However, special consideration should begiven to their use where it is intended t ogroup a number o ft hem t ogether, e.g. for boiler house ventilation.
