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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 160, Glass in building Subcommittee SC 1,

Product considerations.

This third edition cancels and replaces the second edition (ISO 12543-4:2011), which has been

technically revised.

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.

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
b) Boiling water 100 ( ) °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 Other characteristics of glass
Heat the three test specimens to a temperature of 100 °C.

In an oven, the heating-up time is dependent on load and the type and thickness of the laminated glass

being tested.

Generally speaking, for samples up to 10 mm thickness this should be assumed to be 30 minutes. For

thick samples, i.e. thicker than 10 mm, a heating-up time of 3 minutes per millimetre glass thickness

shall be assumed. The maximum shall be 2 hours. Alternatively, the heating-up time for samples thicker

than 10 mm may 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.
5.3.3 Procedure B (long high temperature test)
Heat the three test specimens to a temperature of 100 °C.

In an oven, the heating-up time is dependent on the load and the type and thickness of the laminated

glass being tested. Generally speaking, for samples up to 10 mm thickness this should be assumed to be

30 minutes. For thick samples, i.e. thicker than 10 mm, a heating-up time of 3 minutes per millimetre
