23、12519, Windows and pedestrian doors Terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12519 and the following apply. 3.1 closing condition 3.1.1 closed movable parts rest in or at the fixed parts in a way in which they may be fastened (latch

24、ed and/or locked) 3.1.2 fastened where the movable part is restrained at one or more points and shall be described by at least one of the two as listed below 3.1.2.1 latched movable part is returned to its closed position and restrained by either a) a self - engaging fastener or b) a roller catch or

25、 c) a latch 3.1.2.2 locked movable part is further restrained in the closed position by additional operations (of e.g. handle, key, automatic devices or electronic devices) to engage integrated locking devices (e.g. nutbolts or deadbolts) which will affect the products characteristics BS EN 12211:20

26、16EN 12211:2016 (E) 5 3.1.3 secured any action(s) which prevent unauthorised release of the fastening device(s) to allow exit or entry (e.g. child safety, burglary) 3.2 frontal displacement movement of a point on a frame member measured normal to the member 3.3 frontal deflection maximum frontal dis

27、placement of a frame member minus half the sum of the frontal displacements at each end of the member 3.4 relative frontal deflection frontal deflection of a frame member divided by the length of the member over which the frontal deflection was measured, e.g. distance between the ends of the member

28、3.5 test pressure difference between the static air pressures inside and outside of the test chamber Note 1 to entry: The test pressure is positive if the static air pressure inside the chamber of the test apparatus is higher than that outside the test chamber. Note 2 to entry: The test pressure is

29、negative if the static air pressure inside the chamber of the test apparatus is lower than that outside the test chamber. For the purpose of these tests, three sets of test pressure are defined: P1 applied to measure deflections of parts of the test specimen; P2 pulsating pressure applied for 50 cyc

30、les to assess performance under repeated windloads; P3 applied to assess the safety of the test specimen under extreme conditions. The values of P1, P2, P3 are related as follows: P2 = 0,5 P1 and P3 = 1,5 P1. 4 Principles of test Application of a defined series of pressures (positive and negative) a

31、t which measurements and inspections are made to assess relative frontal deflection and resistance to damage from wind loads. 5 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 deflect

32、ing to an extent likely to influence the test results. 5.2 Means for applying controlled test pressure to the test specimen. 5.3 Means of producing rapid changes in test pressure, controlled within defined limits. BS EN 12211:2016EN 12211:2016 (E) 6 5.4 Instrument suitable for measuring the quantity

33、 of air flow into or out of the chamber with an accuracy of 5 % of the measured value for air flows greater than 1 m/h and an accuracy of 0,05 m/h for air flows equal to or smaller than 1 m/h. NOTE 1 Accuracy = (the sum of the amount of the error plus the amount of the expanded measurement uncertain

34、ty). For values of both error and expanded measurement uncertainty see last calibration certificate of the instrument. NOTE 2 For vocabulary of metrology see ISO/IEC Guide 99:2007 5.5 Means of measuring the test pressure applied across the test specimen, within an accuracy of 5 %. 5.6 Devices, such

35、as dial gauges or displacement transducers, for measuring displacements of measured points with a resolution of 0,1 mm and an accuracy of 5 %. 5.7 Means for fitting the measuring devices properly to ensure their stability during the test. 5.8 A measuring tape accurate to 1 mm to measure the necessar

36、y dimensions (e.g. frame members) of the test specimen. 6 Preparation of test specimen 6.1 Set-up of the test specimen The test specimen shall be fixed as intended for use without any twists or bends which may influence the test results. The test specimen shall be fully operable. The stiffness of th

37、e test rig and the fixing of the test specimen to it shall be sufficient to avoid adverse effects on the performance of the test specimen during testing. The test specimen shall be cleaned and surfaces dry. 6.2 Set-up of measuring devices for frontal deflection Measuring devices (see 5.6) shall be f

38、ixed in position at each end and at the centre of the frame member to be measured. Alternatively, a single measuring device shall be fixed at the centre of a rigid beam that is fixed to and supported as close as possible to the ends of the frame member to be measured. NOTE A frame member could be pa

39、rt of the opening element or the fixed frame. For positioning of measuring devices see Figure A.1 to A.4. 7 Test procedure 7.1 Preliminaries The ambient temperature and humidity close to the test specimen shall be within the range of 10 C to 30 C and 25 % to 75 % RH and the test specimen shall be co

40、nditioned thus for at least 4 h immediately before test. The test specimen shall be brought into the defined closing condition in accordance with the manufacturers instructions. Figure B.1 shows the test sequence of the test to be carried out and the set of test pressures and their features to be ap

41、plied. BS EN 12211:2016EN 12211:2016 (E) 7 The test for air permeability in accordance with EN 1026 shall be completed before testing the resistance to wind load to test pressures P1 and P2. 7.2 Deflection test 7.2.1 General Record the length of the members whose frontal deflection is to be measured

42、. NOTE If several displacements or deflections are to be measured, they can be recorded either during one sequence of test pressure steps to P1 or during as many sequences to P1 as there are measurements to be made. 7.2.2 Positive pressure Apply three pressure pulses, each 10 % greater than the test

43、 pressure P1. The time to reach the maximum pressure shall not be less than 1 s and it shall be sustained for at least 3 s. All the gauges shall be set to zero or have their initial reading recorded. Apply test pressure equal P1 according to the classification required for the test specimen, at a ra

44、te not exceeding 100 Pa/s, either incrementally or continuously. When the pressure P1 has been applied for 30 s, record the required frontal deflection(s) or frontal displacement(s). Reduce the test pressure to 0 Pa, at a rate not greater than 100 Pa/s and after (60 5) s record the residual frontal

45、deflection(s) or frontal displacement. 7.2.3 Negative pressure Apply procedure specified in 7.2.2 using negative test pressures. 7.3 Repeated pressure test The test specimen shall be subjected to 50 cycles including negative and positive pressures, with the following features: test pressure equal P2

46、; first step is negative, next is positive as is the last of the sequence of 50 impulses; variation from P2 to +P2 and the reverse shall take (7 3) s; value P2 is maintained at least for (7 3) s. After completion of the 50 cycles, open and close the moving parts of test specimen and note damage or f

47、unctioning defects if any. Repeat the test for air permeability in accordance with EN 1026. 7.4 Safety test The test specimen shall be subjected to one cycle including negative and positive test pressure with the following features: test pressure equal P3; negative test pressure is applied first; va

48、riation from 0 Pa to P3 and back from P3 to 0 Pa shall take (7 3) s, the maximum test pressure P3 shall be maintained for (7 3) s; BS EN 12211:2016EN 12211:2016 (E) 8 positive test pressure is applied after a (7 3) s rest at 0 Pa; variation from 0 Pa to +P3 and back to 0 Pa shall be the same duratio

49、n as for the negative test pressure -P3. After the safety test record whether the test specimen remains closed and describe any parts of the test specimen which have become detached. 8 Deflection Deflection(s) and displacement, under pressure steps +P1 and P1 shall be recorded. Relative frontal deflections shall be calculated in the form of fractions with the numerator equal to 1 and the denominator expressed to 3 significant figures. 9 Repeated pressure Record any damage and operating defects. 10 Safet
