Foreword
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. 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
International 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 Standards
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 subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
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 12543-4:1998), which has been technically
revised.
ISO 12543 consists of the following parts, under the general title Glass in building — Laminated glass and
laminated safety glass:

Test methods for durability
1 Scope
This part of ISO 12543 specifies test methods in respect of resistance to high temperature, humidity and
radiation for laminated glass and laminated safety glass for use in building.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

energy transmittance, ultraviolet transmittance and related glazing factors

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12543-1 and ISO 12543-2 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.
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 least one original edge shall not be covered.
ISO 12543-4:2011(E)
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) 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 altered. 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-temperature 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
+0
b) Boiling water 100 ( ) °C
−2
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 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 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 glass
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. 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.

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 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 faults occurring in test specimen.
