28、an that outside the test chamber. 3.3 air permeability amount of air passing through all joints between casement or leaf and frame profiles of a test specimen caused by the test pressure Note 1 to entry: Air permeability should be expressed in cubic metres per hour (m3/h). 3.4 opening joint line of

32、ach test pressure measurement of the air permeability with a suitable test device. 5 Test apparatus 5.1 A chamber with an open side to which the test specimen can be fitted. It shall be constructed so as to be able to withstand the test pressures without deflecting to an extent likely to influence t

BS EN 1026:2016EN 1026:2016 (E) 7 NOTE 1 Accuracy = (the sum of the amount of the error plus the amount of the expanded measurement uncertainty). For values of both error and expa

The test specimen shall be fully operable. The test specimen shall be cleaned and surfaces dry. Ventilation devices, if any, shall be ta

38、hus for at least 4 h immediately before testing. Temperature shall be measured to within 3 C and relative humidity to within 5 %. Atmospheric pressure shall be measured to within 1 kPa. The test pressure shall be applied in steps of 50 Pa up to 300 Pa and from 300 Pa in steps of 150 Pa. The air perm

For air permeability under 3,0 m3/h the accuracy shall be 0,30 m3/h. 7.2 Air permeability of test chamber 7.2.1 General Determine the procedure to follow in accordance with what is known about the air permeability of the test chamber. 7.2.2 Test

40、 chamber with known air permeability Assume the air permeability of the test chamber is zero if it is less than 5 % of the maximum air permeability permitted throughout the range of the classification that is attributed to the test specimen. When this is not so, measure the air permeability of the t

41、est chamber as described in 7.2.3 unless it is known and shown to be approximately constant within the limit of accuracy of the measurement recorded by the test laboratory. In no case shall the air permeability of the test chamber exceed 30 % of the overall air permeability of the test specimen and

42、the test chamber. 7.2.3 Test chamber with unknown air permeability Seal all joints in the test specimen with adhesive tape or an airtight sheet covering the whole test specimen. BS EN 1026:2016EN 1026:2016 (E) 8 Measure the air permeability of the test chamber with negative test pressures as describ

43、ed in 7.4, but without pressure pulses. After the determination of the air permeability of the test chamber remove the adhesive tape or airtight sheet covering the test specimen. In no case shall the air permeability of the test chamber exceed 30 % of the overall air permeability of the test specime
