BS EN 13541:2012EN 13541:2012 (E) 4 Introduction The choice of an explosion pressure resistant glazing material (e.g. security and/or anti terrorism glazing product) in an individual case should be estab

18、lished by the user. Experts in the field of explosions are able to determine in most situations the expected level and duration of the shock wave, based on the type of explosion and the distance from the heart of the explosion. The classification of explosion pressure resistance is based on the maxi

19、mum overpressure of the reflected shock wave and the duration of the overpressure phase. BS EN 13541:2012EN 13541:2012 (E) 5 1 Scope This European Standard specifies a test method, performance requirements and classification for explosion pressure resistant glazing for use in buildings. The explosio

20、n pressure resistant glazing is intended to offer resistance against explosives with respect to human safety. This European Standard concerns a method of test against blast waves generated using a shock tube or similar facility to simulate a high explosive detonation. The classification is only vali

21、d for tested glass sizes of about 1 m2. Based on theoretical considerations and/or experimental work, the results can be used for estimating the explosion-pressure-resistance of other glass sizes. NOTE 1 The resistance classes are not assigned to specific situations. For each individual case the ind

22、ividual who specifies, if necessary with the help of experts in the field of explosion, should be consulted. NOTE 2 The protection provided by explosion-resistant-glazing not only depends on the product itself, but also on the design and fixing of the glass. 2 Normative references The following docu

23、ments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 48, Rubber, vulcanize

27、r, that is designed to face the explosive blast 4 Classification and designation Table 1 specifies the classification of and the appropriate test conditions for explosion pressure resistant glazing. If all three test pieces of the sample fulfil the performance requirements of a certain class accordi

28、ng to Clause 6, and the test conditions lie within the tolerance given in Table 1, then the glazing product may be classified in the relevant class. When a security glass pane achieves a particular class, it also automatically achieves all lower classes. Table 1 Classification of explosion-pressure-

BS EN 13541:2012EN 13541:2012 (E) 7 5 Test pieces for type testing 5.1 Type, dimensions and marking The construction and materials of the test pieces shall comply with the specification of the manufacturer. The test pieces (or the sample) submitt

33、ed for type testing shall be representative of the normal production. The dimensions of the test pieces shall be: length (1100 5) mm; width (900 5) mm. The edges of the test pieces should be raised for ease of handling. The sample shall be identified with a permanent label or removable label, which

34、may not be removed, indicating, as a minimum, the attack face of the product. 5.2 Number of test pieces The sample submitted for testing shall consist of three test pieces for each attack face and each class for which testing shall be required. NOTE One extra test piece should be supplied in case of

35、 transport breakage or other logistic handling. 6 Requirements Each of the three test pieces of a sample, according to Clause 5, submitted for testing, shall comply with the following requirements when tested according to Clause 7: the test piece shall not have any “through“ holes, from the front to

36、 the back; no openings from the front to the back as defined in this standard shall be permitted between the clamping frame and the edges of the test piece. NOTE An opening between the clamping frame and the edges of the test piece can be caused by insufficient clamping pressure. If so, the test can

37、 be repeated with a higher clamping pressure. In this case the test report shall state the applied clamping pressure. 7 Test Method 7.1 Apparatus 7.1.1 Specimen holder The specimen holder shall be intrinsically rigid, and rigidly fixed onto a solid foundation and/or into solid masonry. The specimen

38、holder shall have facilities to ensure: plane parallel clamping of the test piece in a vertical position; support of the test piece only by the frame; BS EN 13541:2012EN 13541:2012 (E) 8 clamping of the edges on all sides over an edge width of (50 10) mm; clamping between rubber strips of (50 2) mm

39、wide and (4 1) mm thick, and hardness (50 10) IRHD in accordance with ISO 48; a clamping pressure of (14 3) N/cm2; around the edges a shield not less than 1000 mm wide and/or meeting the wall of the blast tube; that the surface of the attack face of the shield is plane with the surface of the specim

40、en holder; that the surface of the attack face of the test piece recesses not more than 20 mm behind the surface of the specimen holder. 7.1.2 Device for generating the explosive blast A shock tube or a similar device for generating the desired explosive blast shall ensure the consistent reproductio

41、n of a plane shock wave normal to the attack face of the specimen. The shock wave shall simulate this from a spherical non-fragmenting high explosive charge. The overpressure phase should be of a form which can be related to that from a spherical charge of a known weight of trinitrotoluene (TNT) det

42、onating at a known distance. 7.1.3 Measuring device The measuring device shall permit the determination of the magnitude and time of development of the overpressure of the shock wave reflected from the attack face of the specimen with an accuracy of 5 %. 7.2 Preparation of test procedure 7.2.1 Test

The test piece shall be stored for at least 12 hours prior to the test in that range. The ambient testing conditions may be (18 10) C. 7.2.2 Test procedure For each test, the f

44、ollowing procedure shall be followed: clamp the test piece into the specimen holder according to 7.1.1; ensure that the edges of the test piece fully contact the supporting surface; determine the target values for the maximum overpressure, the positive specific impulse and the duration of the overpr

45、essure phase according to the requested class; initiate the blast load; measure the pressure-time parameters of the reflected blast wave; determine the actual values of the maximum overpressure and duration of the overpressure phase; inspect the test piece for openings penetrating the whole thicknes

46、s of the sample and for openings from the front to the back between frame and edges. NOTE Each test piece may be exposed to only one blast, as each blast causes weakening.
