Overview

ISO 3008-1:2019 - Fire resistance tests - Door and shutter assemblies - Part 1: General requirements specifies a standardized method for determining the fire resistance of door and shutter assemblies intended for vertical separating elements. Used together with ISO 834-1, this document covers a wide range of assemblies (hinged, sliding, rolling, folding, tilting doors, removable panels, air transfer grilles and self-closing openable windows) and sets out general test arrangements, safety and conditioning requirements for reliable fire-resistance testing.

Key Topics

• Scope and terminology: Definitions relevant to door and shutter assemblies, associated and supporting constructions, gaps, cills and door hardware.
• Test specimen requirements: Guidance on specimen size, number, design, construction and verification prior to testing.
• Installation and supporting construction: How to mount test specimens, detailing associated and supporting constructions, restraints, and allowable gaps to reproduce realistic boundary conditions.
• Conditioning / pre-conditioning: Requirements for moisture conditioning and mechanical pre-conditioning (e.g., “cycling” of doors/shutters) to simulate in-service wear before fire testing.
• Instrumentation and measurements:
  • Furnace and unexposed-face temperature measurement (thermocouples and locations)
  • Maximum temperature monitoring and door frame temperature
  • Pressure and heat-flux measurement methods
  • Deflection and retention-force measurement procedures
• Test procedure and performance criteria: Procedures for conducting the fire-resistance test and evaluating performance against integrity and insulation criteria.

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

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.
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.

7.3.4 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.
14 © ISO 2019 – All rights reserved

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.

8 Conditioning
8.1 Moisture content
The test specimen shall be conditioned in accordance with ISO 834-1. Requirements for conditioning of
supporting constructions are given in Annex A.
8.2 Mechanical
Some product standards exist for certification purposes that require mechanical testing before the
start of the fire test. Durability requirements are given in the relevant product standard. Where a
relevant product standard does not exist, the following preconditioning shall be performed before the
start of the fire test exposure:
The testing laboratory shall be satisfied that the door leaf, panel or shutter curtain operates
satisfactorily. A series of 50 opening/closing cycles of at least 75° for side-hung doorsets and at least
300 mm for sliding doorsets and shutters shall precede the fire test.
9 Application of instrumentation
9.1 Temperature measurements
9.1.1 Furnace-temperature measuring instrument
Plate thermometers shall be provided in accordance with ISO 834-1. They shall be evenly distributed
over a vertical plane 100 mm from the nearest plane of the test construction; see Figure 13. There shall
be at least one plate thermometer for every 1,5 m of the exposed surface area of the test construction,
subject to a minimum of four. The plate thermometer shall be oriented so that “side A” faces the back
wall of the furnace.

9.1.2 Unexposed-face thermocouples
9.1.2.1 Where no evaluation against the insulation criteria is required of the door or shutter assembly,
or any part thereof, no temperature measurements are required.
9.1.2.2 Where it is required to evaluate compliance with the insulation criteria, thermocouples of the
type specified in ISO 834-1 shall be attached to the unexposed face for the purpose of obtaining the average
and maximum surface temperatures. 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, such
as when testing air transfer grilles, an alternate thermocouple and pad shall be used as described in 4.3.
Examples of the location of unexposed-face thermocouples are shown in Figures 14 to 27.
