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 3009 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Fire
containment.
This second edition cancels and replaces the first edition (ISO 3009:1976), which has been technically revised.

Introduction
This International Standard contains specific requirements for fire resistance testing which are unique to
glazed elements used in building construction. The requirements for these glazed elements are intended to be
applied, as appropriate, in conjunction with the detailed and general requirements given in ISO 834-1.

INTERNATIONAL STANDARD ISO 3009:2003(E)

Fire-resistance tests — Elements of building construction —
Glazed elements
SAFETY PRECAUTIONS — The attention of all persons concerned with managing and carrying out
this fire resistance test is drawn to the fact that fire testing can be hazardous and that there is a
possibility that toxic and/or harmful smoke and gases could be evolved during the test. Mechanical
and operational hazards can also arise during the construction of the test elements or structures, their
testing, and disposal of test residues.
An assessment of all potential hazards and risks to health shall be made and safety precautions shall
be identified and provided. Written safety instructions shall be issued. Appropriate training shall be
given to relevant personnel. Laboratory personnel shall ensure that they follow written safety
instructions at all times.
1 Scope
This International Standard provides a test method for determining and assessing the fire resistance
performance of both insulated and uninsulated glazed elements of building construction, when those elements
are exposed to heating on one face. It is applicable to glazed separating elements such as screens, walls of
glass blocks and other light-transmitting assemblies used in vertical, inclined or horizontal orientations, and to
all separating elements containing glazing intended to be assessed in accordance with ISO 834-1 — except
for doors and shutter assemblies, which are intended to be tested in accordance with ISO 3008. It is directly
applicable to planar elements, but also gives guidance on the testing of non-planar elements such as
pyramids.
The application of the test results to other, untested, forms of construction is acceptable only when the
construction complies with the field of direct application given in this International Standard or when it is
subjected to a field of extended application analysis in accordance with ISO/TR 12470.
NOTE Since ISO/TR 12470 gives only general guidelines, specific extended application analyses are to be
performed only by persons expert in fire-resistant constructions.

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.

3 Terms, definitions and symbols
For the purposes of this document, the terms and definitions given in ISO 13943, the following terms and
definitions, and the symbols given in ISO 834-1, apply.
3.1
aspect ratio
ratio of the exposed height to the exposed width of the glass
3.2
associated construction
specific construction in which the glazed element is to be installed in practice and which is used to close off
the furnace and provide the levels of restraint and thermal heat transfer to be experienced in normal use
3.3
expansion allowance
difference in dimension between the pane or unit and the opening/aperture in the frame or other method of
attachment into which the panes or units are mounted, available for expansion
NOTE The dimensions are measured in two directions (e.g. vertical and horizontal for a vertical glazed element). See
dimension y –x in Figure 1.
y aperture width
y aperture height
x visible glass width

3.4
fire-resistant gypsum board
gypsum board with increased fire resistance as a result of additives to the formulation as specified in
ISO 6308
3.5
glass
rigid transparent or translucent material installed in elements of construction for the purpose of vision or to
allow the passage of light
3.6
glass edge cover
depth of glass retained by the glazing system
NOTE Half the difference between the pane dimension and the exposed dimension, assuming that the pane is
centrally glazed into the opening. See dimension w in Figure 2.

3.7
glazed element
element containing transparent or translucent panes or units retained in frames or other methods of
attachment or units mounted or attached together to provide a barrier
3.8
horizontal glazed element
glazed element intended for installations with inclinations of from 0° up to and including 25°
3.9
inclination
angle of installation relative to a horizontal plane (between 0° and 90°)
3.10
inclined glazed element
glazed element intended for installation with inclinations of from greater than 25° up to and including 80°
3.11
insulated glazing
fire-resistant glazing that satisfies both the integrity and insulation criteria for the anticipated fire-resistance
period
3.12
mullion
vertical framing member separating and supporting two adjacent panes of glass or panels
3.13
orientation
direction of fire exposure with respect to the face of the specimen
EXAMPLE For inclined specimens, orientation is from underneath when using a floor furnace for conducting the test.

3.15
supporting construction
construction that could be required for the testing of some glazed elements into which the test specimen is
assembled

transom
horizontal framing member separating and supporting two adjacent panes of glass or panels
3.17

fire resistance period, but which is not intended to provide insulation
3.18
vertical glazed element
glazed element intended for installation with inclinations of from greater than 80° up to and including 90°
