These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references subsequent amendments to or revi- sions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

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 square meters (m2).4 Principle of testApplication 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 ApparatusThe basic test apparatus shall include:a) an opening to which the test specimen can be fitted, to simulate the structural open- ing of the product on site.b) device(s) to provide controlled air pressure, above atmospheric air pressure, to the exposed surface of the specimen.c) device(s) to measure the amount of airflow with an accuracy of + 5%. It shall be cali- brated so as to give airflow in normal conditions (20°C, 101 kPa).d) device(s) 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 prepared 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 specimena) The test specimen shall be installed in accordance with the manufacturer’s standard or published installation 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 running production.c) The test specimen shall be clean and the surfaces dry.d) Any ventilation, drainage or "weep holes" 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.e) Minimum dimensions of specimen see table 1.Table 1 - Minimum dimensions of specimenCommercial and garage doorsWidth: 2 000 mmHeight: 2 000 mmIndustrial doorsWidth: 3 500 mmHeight: 3 000 mm7 Test procedure7.1 PreliminariesThe test specimen shall be conditioned for at least 4 h within the range 10°C to 30°C and 25%to 75% relative humidities immediately before testing.Temperature shall be measured within + 3°C.Atmospheric pressure shall be measured within + 1 kPa. The pressure shall be applied up to 50 Pa.7.2 ProcedureThe residual air permeability shall be measured prior to the specimen test.The diagrams of pressure sequences given in Annex A may be helpful for a clear under- standing.7.2.1 Air permeability with positive pressure shall be carried out first. Negative pressure shall be carried out only if required.7.2.2 Air permeability of specimen fitted to the test rig shall be measured.7.2.3 The test specimen shall be opened and closed at least once before finally secured in the closed position.7.2.4 Apply three air pressure pulses, to position the seals, the rate of application being over a period of not less than one second. Maintain each pulse for at least three seconds.maxThese pulses shall produce a pressure 10% greater than the maximum pressure PrequiredLicensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 09:17:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSIfor the test.7.2.5 The air pressure in the test rig is then raised up to 50 Pa.The duration should be such that air pressure in the test rig is adequately stabilised before reading the value linked to air permeability.7.2.6 Calculate the air permeability according to the formula:Airleakage m3 /h Residual airleakage m3 /h Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 09:17:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSIStructural opening m2 8 Test reportThe test report shall state the devices used for the test and also record the location of any air leakage observed, on a drawing or a photograph of the test specimen.The report shall contain as a minimum the following information:a) date of the test report;b) reference to this standard;c) name of the approved laboratory, if applicable;d) all necessary references to identify the specimen;e) all relevant details concerning the dimensions of the specimen, its materials, design, con- struction and manufacture and its finished surface and fittings and also its method of de- livery;f) drawings of details of the specimen shall be of a suitable scale;g) identification of the test equipment;h) test method;i) test procedures, including storage and conditioning prior to test and mounting the speci- men ready for test;j) test climates used;k) location of air leakage, if detectable;l) take the overall area (m2) into account when to calculate the specific airflow in m3/ m2h(see 3.2);m) air permeability result;n) summary with observations;o) determine the classification according to EN 12 426;p) signature of the responsible person.Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 09:17:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSIAnnex A (normative)Air pressure sequence for test rig 3 s 1 1 sKeyOpening and closing operation1 Stabilized pressureBS EN12427:2000BSI389 Chiswick High RoadLondonW4 4AL||||||||| BSI Ð British Standards Institution||||||| BSI is the independent national body responsible for preparing British Standards.
