3、word Date Comments This British Standard is the official English language version of EN 124272000. The UK participation in its preparation was entxusted by Technical Committee B38, Doors, windows, shutters, hardware and curtain walling, to Subcommittee B3W5, Industriai, commercial and garage doors a
4、nd gates, which has the responsibility to: - aid enquirers to understand the te*, - present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; - monitor related international and European developments and promulgate
5、 them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary.

11、 433-2 apply. In addition the following definitions also apply: 3.1 Air permeability: ability of a test specimen in relation to the overall area, when in closed position, to allow air flow, expressed in m3/m2 h. 3.2 Overall area: the area of the structural opening of the specimen, expressed in squar
12、e meters (m2). 4 Principle of test Application of air pressure (positive or negative) on the external or internal surface of the test specimen whilst a measurement of the airflow is made with a device according to 5 c). 5 Apparatus The basic test apparatus shall include: a) an opening to which the t
13、est specimen can be fitted, to simulate the structural open- ing of the product on site. b) device( to provide controlled air pressure, above atmospheric air pressure, to the exposed surface of the specimen. c) device) to measure the amount of airflow with an accuracy of +. 5%. It shall be Cali- bra
14、ted so as to give airflow in normal conditions (20C, 1 O1 kPa). d) device) for measuring air pressure with an accuracy of 5%. e) a means of sealing all joints of the specimen when required. NOTE The test rig should not be designed to increase the performance of the specimen. The test rig shall be pr
15、epared so that it is able to withstand the pressures applied during the test, without deflecting to an extent likely to impair jointing or to impose bending stresses. 6 Preparation of test specimen a) The test specimen shall be installed in accordance with the manufacturers standard or published ins
16、tallation instructions. b) The test specimen shall consist of parts, which in detail conform to the production level of quality. Whenever possible the test specimen should be newly made. Doors and parts in stock are to be regarded as newly made if they fully comply with the specification of the runn
17、ing production.

18、“ shall be taped up or left open according to the purpose of test and this purpose and state shall be noted and recorded. In most cases, air can pass through both fixed and opening joints.
