(Main)Fire-resistance tests — Door and shutter assemblies
Fire-resistance tests — Door and shutter assemblies
ISO 3008:2007, used in conjunction with ISO 834-1, specifies a method for determining the fire resistance of door and shutter assemblies designed primarily for installation within openings incorporated in vertical separating elements, such as hinged and pivoted doors, horizontally sliding and vertically sliding doors, including articulated sliding doors and sectional doors, steel single-skin folding shutters (un-insulated), other sliding, folding doors, tilting doors, rolling shutter doors and removable panels in walls. This method can also be used to determine the fire resistance of non-loadbearing horizontal doors by analogy. However, these are not specifically addressed here and the field of direct application is not valid for horizontally oriented doors. No requirements are included for mechanical conditioning, e.g. "shakedown" or durability, as these are included in the relevant product standard, nor for smoke leakage testing of doors and shutters; for the latter, see ISO 5925-1.

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 3008 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Fire
containment.
This third edition cancels and replaces the second edition (ISO 3008:2006), which has been technically
revised, specifically with changes to the wording of the Note to Figure 17, to 9.1.2.5 and to the list in 9.2.5,
and minor editorial changes to improve consistency of style and clarity.

INTERNATIONAL STANDARD ISO 3008:2007(E)
Fire-resistance tests — Door and shutter assemblies
CAUTION — The attention of all persons concerned with managing and carrying out this
fire-resistance test is drawn to the fact that fire testing may be hazardous and that there is a
possibility that toxic and/or harmful smoke and gases may be evolved during the test. Mechanical and
operational hazards may 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, used in conjunction with ISO 834-1, specifies a method for determining the fire
resistance of door and shutter assemblies designed primarily for installation within openings incorporated in
vertical separating elements, such as
⎯ hinged and pivoted doors,
⎯ horizontally sliding and vertically sliding doors, including articulated sliding doors and sectional doors,
⎯ steel single-skin folding shutters (un-insulated),
⎯ other sliding, folding doors,
⎯ tilting doors,
⎯ rolling shutter doors,
⎯ removable panels in walls.
This method can also be used to determine the fire resistance of non-loadbearing horizontal doors by analogy.
However, these are not specifically addressed here and the field of direct application given in Clause 13 is not
valid for horizontally oriented doors.
No requirements are included for mechanical conditioning, e.g. “shakedown” or durability as these are
included in the relevant product standard or for smoke leakage testing of doors and shutters; for the latter, see
ISO 5925-1.

ISO 3008:2007(E)
5 Test conditions
Test conditions require the application of the heating and pressure conditions of the standard test as defined
in ISO 834-1.
6 Test specimen
6.1 Size of specimen
The test specimen and all its components shall be full size. When this is restricted by the size of the opening
of the furnace (which is normally 3 m × 3 m), the door or shutter assembly shall be tested at the maximum
size possible and the fire resistance of the full sized assembly shall be derived by an extended application
analysis. However, the minimum dimensions of supporting construction shall not be less than that prescribed
in 7.3.1.
6.2 Number of specimens
The number of test specimens shall be selected as described in ISO 834-1. If testing is carried out from one
side only, it shall be stated in the test report whether this is due to the symmetrical nature of the door or
because it is required to resist fire from one side only.
6.3 Design of specimen
6.3.1 The design of the test specimen and the choice of supporting construction shall take into account the
requirements of 7.3 if the widest field of direct application is to be achieved.
6.3.2 Where the door or shutter assembly incorporates side, transom or flush over panels, whether glazed
or unglazed, these shall be tested as part of the door or shutter assembly. The side panel shall always be on
the latch side.
6.3.3 The test specimen shall be fully representative of the door or shutter assembly as intended for use in
practice, including any appropriate surface finishes and fittings that are an essential part of the specimen and
that can influence its behaviour in a test construction.
6.4 Construction
The test specimen shall be constructed as described in ISO 834-1.
6.5 Verification
6.5.1 The sponsor shall provide a specification to a level of detail sufficient to allow the laboratory to
conduct a detailed examination of the specimen before the test and to agree on the accuracy of the
information supplied. ISO 834-1 provides detailed guidance on verification of the test specimen.
6.5.2 When the method of construction precludes a detailed survey of the specimen without having to
permanently damage it, or if it is considered that it will subsequently be impossible to evaluate construction
details from a post-test examination, then one of two options shall be exercised by the laboratory:
⎯ either the laboratory shall oversee the manufacture of the door or shutter assembly(ies) subjected to the
test,
⎯ or the sponsor shall, at the discretion of the laboratory, be requested to supply an additional assembly or
that part of the assembly that cannot be verified (e.g. a door leaf) in addition to the number required for
the testing. The laboratory shall then choose freely which of these shall be subjected to the testing and
which shall be used to verify the construction.

7 Installation of test specimen
7.1 General
7.1.1 The test specimen shall be installed as intended for use in practice, incorporating all hardware and
other items that can influence the performance of the specimen.
7.1.2 The test specimen shall be mounted in a supporting construction, the field of application of which
covers the type (see 7.3.1) in which it is intended for use. The design of the connection between the test
specimen and the supporting construction, including any fixings and materials used to make the connection,
shall be as intended for use in practice and shall be regarded as part of the test specimen.
7.1.3 The whole area of the test specimen, together with at least the minimum dimensions of the supporting
construction required by 7.3.1, shall be exposed to the heating conditions.
7.2 Supporting construction
The fire resistance of any supporting construction shall not be determined from a test in conjunction with a test
specimen and shall be at least commensurate with that anticipated for the test specimen.
7.3 Test construction
7.3.1 Associated and supporting construction
The space between the specimen and the frame shall be filled with either
⎯ associated construction, or
⎯ supporting construction.
There shall be a minimum zone, 200 mm wide, of supporting construction exposed within the furnace each
side and over the top of the aperture into which the test specimen is fixed. The thickness of the supporting
construction may be increased outside of the 200 mm zone. The test construction may incorporate more than
one test specimen providing that there is a minimum separation of 200 mm between each specimen and
between the specimens and the edge of the furnace.
7.3.2 Associated construction
When the test specimen is always installed in a specific, normally proprietary form of construction, that is
permanently associated with its intended use in practice, then the specimen shall be installed in a sample of
this associated construction.
7.3.3 Supporting construction
7.3.3.1 Where the test specimen is not permanently associated with a specific form of construction, the
area between the test specimen and the support frame shall be filled with a rigid or flexible standard
supporting construction as specified in ISO 834-8.
7.3.3.2 The choice of standard supporting construction shall reflect the range of intended use for the door
or shutter assembly. The rules governing the applicability of the chosen standard supporting construction to
other end use situations are given in Clause 13.
7.3.3.3 Figures 1 to 8 illustrate the use of supporting constructions in conjunction with the mounting of
specimens of different types.

7.3.4 Restraint on supporting construction
7.3.4.1 For flexible standard supporting constructions and all associated supporting constructions, the
partition or wall shall be erected so that it can distort freely perpendicular to the plane of the construction along
the vertical edges, i.e. there shall be a free edge at each end of the construction.
7.3.4.2 For rigid standard supporting constructions, the wall shall be erected with no freedom to distort
perpendicular to the plane of the wall along the vertical edges, i.e. it shall be fixed to the inside of the test
frame as in normal practice.
7.3.4.3 If the bottom of the test specimen is at floor level in practice, then, at the bottom of the aperture,
continuity of the floor shall be simulated using a solid, non-combustible rigid material that has a minimum
width of 200 mm on each side of the assembly, i.e. from the exposed to the unexposed face. The furnace floor
can be regarded as part of the simulation of the floor continuity provided that it is level with the base of the
assembly. If a cill detail is incorporated as part of the door or shutter assembly, this shall be incorporated
within, or placed on top of, the extension. If the test specimen is not to be used at floor level, and provided that
it has a frame detail to all four sides of the aperture, then it may be mounted simply within the thickness of the
wall, without the extension.
If the specimen is tested in conjunction with a non-combustible floor, then this might not represent the
situation when the specimen is installed above a combustible flooring such as timber or carpet.
7.4 Gaps
7.4.1 The adjustment of the door leaf, leaves or shutter and gaps shall be within the tolerances of the
design values stipulated by the sponsor. These shall be representative of those used as intended for use in
practice, so that appropriate clearances exist, e.g. between the fixed and moveable components.
7.4.2 In order to generate the widest field of direct application, the gaps shall be set between the middle
value and the maximum value within the range of gaps given by the sponsor.
NOTE A door or shutter assembly with a specified range of gaps from 3 mm to 8 mm is tested with gaps set between
5,5 mm and 8 mm.
Examples of gap measurement are given in Figures 9 to 12.
