Fire resistance tests — Door and shutter assemblies —
Part 1:
General requirements

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 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.

which are normally in the open position.
4 Test equipment

4.1 The test equipment shall be as specified in ISO 834-1. The furnace used shall be related to the

orientation of the test specimen. For vertical specimens, the wall testing furnace is suitable, for horizontal

specimens, the floor furnace is applicable.

4.2 Measurement of heat flux from the unexposed surface of specimens shall be made as described in 9.5.

4.3 Where it is not possible to apply disc thermocouples as specified in ISO 834-1 to the unexposed

surface of the test specimen, due to the size or shape of the specimen, or when the dimension of the

element to be measured is less than 12 mm, such as when testing air transfer grilles, an alternate

thermocouple and pad may be used. Instead of copper discs, twisted thermocouple wire may be used.

The wire leads of the thermocouple are to have an immersion under the pad and be in contact with

the unexposed surface for not less than 25 mm. The hot junction of the thermocouple is to be placed

approximately under the centre of the pad. The pad is permitted to be deformed in order to be held

firmly against the surface of the element being measured and is to fit closely about the thermocouple.

When the blade of the air transfer grille or other parts of the test specimen is less than the specified

pad size, reduce the pad to match the element being measured. The pad length shall be as specified and

parallel to the test specimen length. If the modified thermocouple pad cannot be placed on the contour

of the surface, then no thermocouple is required at that location. The wires for the thermocouple in the

length covered by the pad shall not be heavier than 0,82 mm and are to be electrically insulated with

heat-resistant and moisture-resistant coatings.
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 or the self-closing

openable window 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.

4 © ISO 2019 – All rights reserved
---------------------- Page: 10 ----------------------
ISO 3008-1:2019(E)

6.3.2 Where the door or shutter assembly incorporates air transfer grilles or 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.

ISO 3008-1:2019(E)
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 applicabi
