Overview

EN ISO 12543-4:2021 - Glass in building: Laminated glass and laminated safety glass - Part 4: Test methods for durability specifies laboratory test methods to assess the durability of laminated glass and laminated safety glass used in buildings. The standard defines procedures for resistance to high temperature, humidity (with and without condensation) and radiation exposure, and describes test specimen requirements, expression of results and reporting.

Key topics and technical requirements

• Scope: Durability tests for laminated glass and laminated safety glass intended for building applications (resistance to heat, humidity and radiation).
• Test specimens: Specimens must be representative of production; cut samples must retain at least one original edge. Edge protection/sealing in specimens must match the final product. (Retesting guidelines are provided in Annex A.)
• High-temperature test:
  • Purpose: check stability under prolonged high temperature (monitoring bubbles, delamination, cloudiness).
  • Minimum specimen size: 300 mm × 200 mm; three specimens required.
  • Two procedures are defined (short and long high-temperature tests).
• Humidity test:
  • Includes methods with condensation and without condensation to evaluate moisture-induced degradation of interlayers and adhesion.
• Radiation tests:
  • Simulated solar radiation methods are specified, including:
    • Method A: Radiation wall
    • Method B: Mercury vapour arc lamp
    • Method C: Xenon arc source
  • Procedures cover exposure, measurement and expression of effects (including specific notes for fire‑resistant laminated glass).
• Reporting & results: The standard prescribes how to express results and what to include in the test report to ensure reproducibility and traceability.

Practical applications and users

EN ISO 12543-4:2021 is used for:

• Manufacturers of laminated and laminated safety glass for product development, production control and quality assurance.
• Independent testing laboratories performing durability and certification testing.
• Architects and façade engineers specifying glazing for long-term performance under climatic and solar loads.
• Specifiers and building authorities requiring objective evidence of resistance to heat, moisture and solar radiation.
• Product certification bodies and compliance programs that reference ISO/CEN durability methods.

Typical uses include assessing new interlayer formulations, validating edge treatments and seals, comparing material options for façades, and demonstrating compliance during type testing.

Related standards

• ISO 12543-1 - Definitions and component descriptions for laminated glass
• ISO 4892-2 - Xenon-arc exposure methods (referenced for radiation testing)
• ISO 9050 - Determination of light and solar transmittance (used when reporting optical changes)

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

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

The original edge should be marked.
If the final product as produced by the fabricator has all its edges sealed or protected, the test specimen
shall also have all its edges sealed or protected.
