17、:2011ISO 12543-4:2011(E) iv ISO 2011 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees

18、. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Intern

19、ational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Sta

20、ndards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subj

ISO 12543-4 was prepared by Technical Committee ISO/TC 160, Glass in building, Subcommittee SC 1, Product considerations. This second edition cancels and replaces the first edition (ISO 12543-4:199

Test specimens shall either be specially manufa

28、ctured 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. The original edge should be marked. If the final product has all its edges sealed/protected, the test specimen shall also have all its edge

29、s 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 least one original edge shall not be covered. BS EN ISO 12543-4:2011ISO 12543-4:2011(E) 2 ISO 2011 All rights reservedTest specimens shall

30、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) shall be used for the test. 5 High-temperature test 5.1 Principle The purpose of this test is to determine whether the l

31、aminated glass and laminated safety glass are able to withstand exposure to high temperatures over an extended period of time without their properties becoming substantially altered. The changes in properties are judged by the occurrence of bubbles, delamination and cloudiness (not discoloration). 5

32、.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-temperature test may be carried out using either an oven or boiling water. The test temperature is 100 C. The tolerances of the

33、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, test 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

34、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 speaking, this should be assumed to be 30 min. Maintain the test temperature for a period of 16 h. Take the test specimens o

35、ut 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 glass surface temperature is lower than 30 C. 5.3.3 Procedure B Heat the three test specimens to a temperature of 100 C. Hea

36、ting-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. For thick samples, i.e. greater than 11 mm, this shall be determined by calibration. Maintain the test temperature for a

37、 period of 2 h.

The assessment of the test samples may be carried out when the glass surfa

38、ce 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 faults occurring in test specimen. NOTE Bubbles, delamination, haze and cloudiness indicate faults, but

39、 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 test specimen showing cracks, and perform the test on a new test specimen in its place. 5.5 Test repor

40、t 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 structure of the laminated glass or laminated safety glass, with nominal thickness of the individual const

41、ituents, 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 test specimen, the number and size of the bubbles, delamination, haze or cloudiness occurring. 6 Humi

42、dity 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 extended period of time without their properties becoming substantially altered. The effects of the humidit

43、y 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 Procedures 6.3.1 Test with condensation Keep the three test specimens vertically over water in a close

44、d 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. BS EN ISO 12543-4:2011ISO 12543-4:2011(E) 4 ISO 2011 All rights reservedNOTE These conditions give a relative humidity of about 100 % and lead to

45、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 5050+C and the relative humidity within the limits of (80 5) %. Adequate spacing b

46、etween 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 occurring in the interlayer (bubbles, delamination, haze and cloudiness) for each test

47、 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-resistant laminated glass and fire-resistant laminated safety glass, only delamination

48、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 glasses to the temperature reached in the humidity test over a long period of time may

49、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 nominal thickness of the individual constituents, in millimetres; d) type of test specimens, incl
