27、43-2 apply. 4 Test specimens Test specimens should be representative of standard production. Test specimens shall either be specially manufactured to the test size or be cut from larger panes. Test specimens with cut edges shall contain at least one edge from the original pane from which it was cut.
28、 The original edge should be marked. If the final product has all its edges sealed/protected, the test specimen shall also have all its edges sealed/protected. The method of supporting the test specimen shall not cover two edges of the test specimen. If the test specimen is cut from a larger pane at
29、 least one original edge shall not be covered. DIN EN ISO 12543-4:2011-12 EN ISO 12543-4:2011 (E) 4 Test specimens shall be inspected prior to the test at a distance between 300 mm and 500 mm in front of a white diffuse background. Only samples free of faults (i.e. bubbles, delamination, cloudiness)
30、 shall be used for the test. 5 High-temperature test 5.1 Principle The purpose of this test is to determine whether the laminated glass and laminated safety glass are able to withstand exposure to high temperatures over an extended period of time without their properties becoming substantially alter
31、ed. The changes in properties are judged by the occurrence of bubbles, delamination and cloudiness (not discoloration). 5.2 Size and number of test specimens The test specimens shall not be smaller than 300 mm 100 mm. There shall be three test specimens. 5.3 Procedures 5.3.1 General The high-tempera
32、ture test may be carried out using either an oven or boiling water. The test temperature is 100 C. The tolerances of the test temperature depend on the test method used and are as follows: a) Oven (100 2) C b) Boiling water 100 (02+) C To remove the risk of thermal breakage in the boiling water, tes
33、t samples should be placed in water at 60 C for 10 min before transferring to the water at 100 C. 5.3.2 Procedure A Heat the three test specimens to a temperature of 100 C. In an oven, the heating-up time is dependent on the load, type and thickness of the laminated glass being tested. Generally spe
34、aking, this should be assumed to be 30 min. Maintain the test temperature for a period of 16 h. Take the test specimens out and allow them to cool to room temperature by storing them vertically under natural convection and radiation. The assessment of the test samples may be carried out when the gla
35、ss surface temperature is lower than 30 C. 5.3.3 Procedure B Heat the three test specimens to a temperature of 100 C. Heating-up time is dependent on the type and thickness of the laminated glass being tested. Generally speaking, for samples up to 11 mm thickness this should be assumed to be 30 min.
36、 For thick samples, i.e. greater than 11 mm, this shall be determined by calibration. Maintain the test temperature for a period of 2 h. DIN EN ISO 12543-4:2011-12 EN ISO 12543-4:2011 (E) 5 Take the test specimens out and allow them to cool to room temperature by storing them vertically under natura
37、l convection and radiation. The assessment of the test samples may be carried out when the glass surface temperature is lower than 30 C. 5.4 Expression of results Inspect the samples at a distance between 300 mm and 500 mm in front of a white diffuse background. Record the number and extent of the f
38、aults occurring in test specimen. NOTE Bubbles, delamination, haze and cloudiness indicate faults, but discoloration does not. Disregard all faults within 15 mm from an original edge and 20 mm from a cut edge. Individual bubbles in the immediate vicinity of inlaid wires are permissible. Disregard a
39、test specimen showing cracks, and perform the test on a new test specimen in its place. 5.5 Test report The following information shall be given in the test report: a) reference to this part of ISO 12543, i.e. ISO 12543-4:2011; b) test procedure used: A (see 5.3.2) or B (see 5.3.3); c) type and stru
40、cture of the laminated glass or laminated safety glass, with nominal thickness of the individual constituents, in millimetres; d) type of test specimens, including cut or special manufacture; type of edge; edge protection; dimensions; e) unsupported and supported edges by the test frame; f) for each
41、 test specimen, the number and size of the bubbles, delamination, haze or cloudiness occurring. 6 Humidity tests 6.1 Principle The purpose of this test is to determine whether the laminated glass and laminated safety glass are able to withstand the effects of humidity in the atmosphere over an exten
42、ded period of time without their properties becoming substantially altered. The effects of the humidity are judged by bubbles, delamination, haze or cloudiness. 6.2 Size and number of test specimens The test specimens shall not be smaller than 300 mm 100 mm. There shall be three test specimens. 6.3
43、Procedures 6.3.1 Test with condensation Keep the three test specimens vertically over water in a closed container for two weeks. Maintain the temperature of the air in the container at 5050+C. Adequate spacing between the test specimens shall be provided. DIN EN ISO 12543-4:2011-12 EN ISO 12543-4:20
44、11 (E) 6 NOTE These conditions give a relative humidity of about 100 % and lead to water condensing on the surface of the test specimen. 6.3.2 Test without condensation Keep the three test specimens vertically for two weeks in a climate chamber and keep the temperature of the air in the container at
45、 5050+C and the relative humidity within the limits of (80 5) %. Adequate spacing between the test specimens shall be provided. 6.4 Expression of results Inspect the samples at a distance between 300 mm and 500 mm in front of a white diffuse background. Record the number and extent of the faults occ
46、urring in the interlayer (bubbles, delamination, haze and cloudiness) for each test specimen. Disregard all faults within 15 mm from an original edge, 20 mm from a cut edge or 10 mm from any crack. Individual bubbles in the immediate vicinity of inlaid wires are permissible. In the case of fire-resi
47、stant laminated glass and fire-resistant laminated safety glass, only delamination shall be considered as a fault. NOTE The interlayers of fire-resistant laminated glass and fire-resistant laminated safety glass are designed to react at high temperatures. The exposure of test specimens of those glas
48、ses to the temperature reached in the humidity test over a long period of time may create bubbles, haze and cloudiness in the interlayer which do not affect the fire-resistant properties so that only delamination will be considered. 6.5 Test report The following information shall be given in the test report: a) reference to this part of ISO 12543, i.e. ISO 12543-4:2011; b) test procedure (6.3.1 or 6.3.2); c) type and structure of the laminated glass or laminated safety glass, with nom
