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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

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/

iso/ foreword .html.

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

SC 1, Product considerations, in collaboration with the European Committee for Standardization (CEN)

Technical Committee CEN/TC 129, Glass in building, in accordance with the Agreement on technical

cooperation between ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition (ISO 12543-1:2011), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— editorial changes have been made;
— definitions in Clause 3 has been modified.
A list of all parts in the ISO 12543 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

This document defines terms and describes component parts for laminated glass and laminated safety

glass for use in building.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1 General
3.1.1
laminated glass

assembly consisting of one sheet of glass with one or more sheets of glass and/or plastic-glazing sheet

material joined together with one or more interlayers (3.2.7)
Note 1 to entry: See ISO 12543-3.
3.1.2
laminated safety glass

laminated glass (3.1.1) classified in accordance with a soft body impact standard where in the case of

breakage the interlayer (3.2.7) serves to retain the glass fragments, limits the size of opening, offers

residual resistance and reduces the risk of cutting or piercing injuries
Note 1 to entry: See ISO 12543-2.

ISO/FDIS 12543-1:2021(E)
3.2 Laminated glass and laminated safety glass
3.2.1
fire-resistant laminated glass
fire-resistant laminated glass with a fire-resistant interlayer

laminated glass (3.1.1) where at least one interlayer (3.2.7) reacts to the high temperature to give the

product its fire resistance

Note 1 to entry: A glass product can only have its fire performance determined and classified when used in a fire-

resistant glazed assembly.

Note 2 to entry: Laminated glass may achieve fire resistance by means of the performance of one or more of its

glass components which are kept after lamination. This laminated glass has to be distinguished from the fire-

resistant laminated glass (3.2.1) with fire resistant interlayer (3.2.7) as defined above.

3.2.2
laminated glass with acoustic properties

laminated glass (3.1.1) where at least one interlayer (3.2.7) increases the sound transmission loss of the

product

Note 1 to entry: The interlayer can be evaluated in accordance with ISO 16940, which measures the mechanical

impedance of laminated glass.
3.2.3
