19、0:2002 (E)4IntroductionThis European Standard is a test method standard, which is intended to classify flat glass products used inbuildings, by performance under impact and by mode of breakage. The classification by drop height corresponds tograded values of energy transmitted by the impact of a per
20、son.The classification system in this European Standard relates to increasing personal safety by:- the reduction of cutting and piercing injuries to persons;- the containment characteristics of the material.BS EN 12600:2002EN 12600:2002 (E)51 ScopeThis European Standard specifies a pendulum impact t
21、est method for single flat panes of glass for use in buildings.The test is intended to classify flat glass products in three principal classes by performance under impact and bymode of breakage.This standard does not specify requirements for applications, nor does it specify requirements for durabil

31、following ways:a) numerous cracks appear, but no shear or opening is allowed within the test piece through which a 76 mmdiameter sphere can pass when a maximum force of 25 N is applied (in accordance with annex A).Additionally, if particles are detached from the test piece up to 3 min after impact,
32、they shall, in total, weigh nomore than a mass equivalent to 10 000 mm2of the original test piece. The largest single particle shall weighless than the mass equivalent to 4 400 mm2of the original test piece;b) disintegration occurs and the 10 largest crack-free particles collected within 3 min after
33、 impact and weighed,all together, within 5 min of impact shall weigh no more than the mass equivalent to 6 500 mm of the originaltest piece. The particles shall be selected only from the portion of the original test piece exposed in the testframe. Only the exposed area of any particle retained in th
34、e test frame shall be taken into account indetermining the mass equivalent.5 Test method5.1 Test apparatus5.1.1 Description of test apparatus5.1.1.1 GeneralThe test apparatus shall comprise:a stable main frame;a clamping frame which is fitted onto the main frame and is used to hold the test piece in
35、 position for the duration ofthe test;a dual tyre impactor with a suspension device and release mechanism.5.1.1.2 Main frame (see Figures 1, 2 and 3)This shall be constructed from welded, or bolted, hot rolled steel channel sections with rounded edges, designed topresent a rigid and flat surface to
36、the sub-frame. The lower cross members shall be securely fixed to a concretefloor.BS EN 12600:2002EN 12600:2002 (E)7NOTE Additional support to the frame can be provided, if required, by means of horizontal steel sections fixed to an adjacentrigid wall (see Figure 2, F2).The dimensions of the main fr
37、ame (see Figure 3) shall be:- internal width: (847 5) mm;- internal height: (1 910 5) mm5.1.1.3 Clamping frame (see Figure 4)Clamping frame, used to hold the test piece in the apparatus, consisting of two rectangular parts which clamp thetest piece along its perimeter. The inner part of the clamping
38、 frame is attached to the main frame.The assembly is held together by a clamping device. The clamping frame shall be suitably rigid to withstand thepressure exerted by the clamping device.The dimensions of the clamping frame shall be:- internal width: (847 5) mm;- internal height: (1 910 5) mmEach p
39、art of the clamping frame shall be fitted with a strip of rubber. The rubber strips shall be the only element incontact with the test piece and shall be (20 2) mm wide and (10 1) mm thick and have a hardness of(60 5) IRHD in accordance with ISO 48.NOTE It is recommended to use polychloroprene or a s
40、imilar material.5.1.1.4 Impactor (see Figures 5 and 6)Impactor consisting of two pneumatic tyres, Tyre 3.50-R8 4PR 1) in accordance with ISO 4251-1, with roundsection and flat longitudinal tread. The tyres shall be fitted to the rims of the wheels that carry two steel weights ofequal mass. The weigh
41、ts shall be dimensioned so that the total mass of the impactor is (50 0,1) kg.NOTE An example of the impactor, using steel with a density of 7 830 kg/m, is shown in Figure 5.5.1.1.5 Suspension system (see Figure 2)The impactor shall be suspended by means of a steel cable of 5 mm in diameter conformi
42、ng to ISO 2408, from abracket attached above the head of the main frame. The bracket shall be rigid to ensure that the point ofsuspension remains stationary during the test and shall be positioned to permit the impactor to strike the centre ofthe test piece.At the highest drop height the angle betwe
43、en the taut suspension cable and the bracket shall not be less than 14from the horizontal.When the impactor is hanging freely, at rest, the distance between the fully inflated tyres and the surface of the testpiece shall not exceed 15 mm and shall not be less than 5 mm (see Figure 2; D) and the cent
44、re line of the impactorshall be within 50 mm radially from the centre of the test piece.1) Tyre 3.50-R8 4PR manufactured by Vredestein can be used for the pendulum test.

Equivalent tyres may be used as longas it is demonstrated that equivalent results will be obtained.BS EN 12600:2002EN 12600:2002 (E)85.1.1.6 Impact release mechanism (see
46、 Figure 2)The impactor release mechanism enables the impactor to be raised and positioned at each of the specified dropheight positions and then to be released so that it swings freely and impacts the test piece. The release cable shallbe connected to the top and bottom ends of the impactor by suita
47、ble links so that the raising force is applied at rightangles to the axis of the impactor. The release mechanism shall ensure that the release cable is maintained at thecorrect orientation at each of the drop heights.5.1.2 CalibrationThe test apparatus shall be calibrated in accordance with annex B
48、in order to ensure that the energy transferred tothe test piece by the impactor during the test carried out on different apparatus is consistent.5.2 Test pieces5.2.1 GeneralEach test piece shall comprise a single pane of glass product and be representative of the normal production of thetype of prod
