14、This document EN 12152:2002 has been prepared by Technical Committee CEN/TC 33 “Doors, windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical
15、text or by endorsement, at the latest by August 2002, and conflicting national standards shall be withdrawn at the latest by August 2002. This European Standard is part of a series of European Standards dedicated to curtain walling products and derives from performance requirements. This European St
16、andard forms part of a series of curtain walling standards as specified in the Product Standard prEN 13830. According to the CENICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republ
17、ic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 12152:2002 (E) 1 Scope This European Standard specifies requirements and classification of air permeability of both fixed
18、and openable parts of curtain walling, under positive and negative static air pressure. NOTE This European Standard applies to curtain walling as specified in prEN 13830. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. The
19、se normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For unda

22、fferential air pressure between the two faces of the test specimen, expressed in Pascals (Pa) 3.2 positive pressure when the outer face is subjected to higher air pressure than the inner face 3.3 negative pressure when the outer face is subjected to lower air pressure than the inner face 3.4 air per
23、meability passage of air through the curtain walling when subjected to positive or negative air pressure The volume being expressed as a rate in cubic metres per hour (m3/h), this rate being related to the overall area of the curtain walling. Alternatively, the rate can be related to the metre lengt

It s
26、hall be expressed in m2 4 Req u rements 4.1 The air permeability for the fixed areas of the curtain walling shall take no account of the passage of air through openable joints and shall be related to the positive pressures applied and the overall area, or the fixed joint lengths, of the test specime
27、n. The air permeability per m2allowed for classification purposes is related to positive test pressures as shown in Table 1, and the air permeability per metre length of joint is related to positive test pressures as shown in Table 2. 4.2 Air permeability performance requirements of a curtain wall s
28、hall be established from Table 1 or Table 2 which are derived from maximum positive test pressures equating to 0,25 of the design wind load as determined in ENV 1991-2-4. For intermediate test pressures (P,) the air permeability allowed (O,) shall be determined using the formula: 213 Q no =Q E O, Pe

In such conditions Table 2 shall apply, based on 0,5 cubic metres per metre per hour (m3/m . h). 4.4 The air permeability for openable parts of curtain walling (e.g. windows within curtain walling facade) shall be relate
