14、Foreword This European Standard 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 identic

15、al text or by endorsement, at the latest by December 2000, and conflicting national standards shall be withdrawn at the latest by December 2000. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Stan

22、n inner face is subjected to higher pressure than outer face 3.4 design wind load load calculated following the procedure specified within ENV 1991 -2-4 and represented in this test with positive and negative test pressures on the test specimen 3.5 increased load (safety load) I ,5 times design wind

This chamber shall be of sufficient strength and rigidity to withstand the test pressures likely to be imposed during the tests. It shall not deflect under test pressure to any extent whic

26、h would affect the performance of the test specimen (Figure 1). Adequate representative structural supports shall be provided to which the specimen shall be attached in accordance with the conditions of use in the works (see also clause 6). The chamber shall be so constructed that the air permeabili

27、ty through it, at pressures up to the maximum air permeability test pressures, does not exceed the permissible air permeability through the specimen, at the same pressures. 5.2 A means for applying controlled positive and negative test pressures to the test specimen. 5.3 A means by which rapidly con

28、trolled changes of positive and negative test pressures may be produced within defined limits. 5.4 A means of measuring the applied positive and negative test pressures, steady or fluctuating, within an accuracy of 15 %. 5.5 Devices for measuring displacements to an accuracy of at least - name of th
