19、 Foreword This European Standard has been prepared by Technical Committee CEN/TC 156 “Ventilation for buildings“, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the lat
20、est by April 2002, and conflicting national standards shall be withdrawn at the latest by April 2002. The annexes A, B and C are normative. Annex D is informative. Warning Attention is drawn to the possible risks associated with legionella, if recirculated water is used or biofilms are allowed to de
21、velop within the facility during weather louvre testing, in order that appropriate precautions are taken to safeguard the health of those involved. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European

23、opy, (c) BSI EN 13030:2001 (E) 4 1 Scope This European Standard specifies a method for measuring the water rejection performance of louvres subject to simulated rain and wind pressures, both with and without air flow through the louvre under test. For the purpose of tests in this standard, a 1000 mm
24、 ? 1000 mm section of weather louvre or the nearest possible blade increment is considered. Weather louvres are designed to restrict the passage of water during rainfall while allowing the passage of air into or from an air distribution system or part of a building. They are used in a wide range of
25、applications, where there may be differences in wind speed and direction, levels of local turbulence, rate and droplet size, distribution of rainfall and surface water flow from the surrounding structure. It is impractical to consider a standard test procedure simulating the whole range of likely co
26、nditions, but this standard provides for heavy rainfall directed on to the louvre surface, with simulated wind pressures. This provides a common basis on which to compare the water rejection performance of weather louvres of different designs. This standard is not intended for the evaluation of weat
27、her performance of pressure relief dampers. The purpose of tests incorporated in this European Standard is as follows: a) Weather tests To establish the weather louvre effectiveness when subjected to wind pressure at various air flow rates. b) Discharge and Entry loss coefficient/Pressure requiremen
28、ts To establish the air pressure loss through the weather louvre at various air flow rates and by calculation the Discharge and Entry Loss Coefficient. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative refere
