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

Part 1:
Definitions and description of component parts
1 Scope
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.
ISO 12543-2, Glass in building — Laminated glass and laminated safety glass — Part 2: Laminated safety
glass
ISO 12543-3, Glass in building — Laminated glass and laminated safety glass — Part 3: Laminated glass
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:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
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.

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
