EN 12600:2002 (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 person.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.SIST EN 12600:2004

The largest single particle shall weighless than the mass equivalent to 4 400 mm2 of the original test piece;b)disintegration occurs and the 10 largest crack-free particles collected within 3 min after impact and weighed,all together, within 5 min of impact shall weigh no more than the mass equivalent to 6 500 mm² 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 the 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 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 the sub-frame. The lower cross members shall be securely fixed to a concretefloor.SIST EN 12600:2004
EN 12600:2002 (E)7NOTEAdditional 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 frame (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 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 part 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.NOTEIt is recommended to use polychloroprene or a similar 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 weights shall be dimensioned so that the total mass of the impactor is (50 ± 0,1) kg.NOTEAn example of the impactor, using steel with a density of 7 830 kg/m³, 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 conforming 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 between the taut suspension cable and the bracket shall not be less than 14°from 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 centre 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. It can be obtained from Vredestein BV,Ingenieur Schiffstraat 370, NL - 7547 RD Enschede, Nederland or Vredestein GmbH, August-Horch-Strasse 7, D - 56070Koblenz, Deutschland.The above tyre does not mean that CEN is recommending the use of this particular tyre. Equivalent tyres may be used as longas it is demonstrated that equivalent results will be obtained.SIST EN 12600:2004
EN 12600:2002 (E)85.1.1.6 Impact release mechanism (see 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 suitable 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 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 product submitted for test.5.2.2 Dimensions of the test piecesThe test pieces shall have the following dimensions:- width(876 ± 2) mm;- height(1 938 ± 2) mmResults obtained with test pieces of these dimensions are valid for classification purposes of the glass productwhatever the service dimensions.5.2.3 Number of test piecesThe test shall be carried out at each drop height on four pieces of identical structure and the same nomi
