Foreword
This European Standard has been prepared by Technical Committee CEN/TC 127 "Fire
safety in buildings", the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication
of an identical text or by endorsement, at the latest by July 2002, and conflicting national
standards shall be withdrawn at the latest by December 2003.
This document has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements
of EU Directive(s).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of
the following countries are bound to implement this document: Austria, Belgium, the Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg,
Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
The classification of the reaction to fire performance of construction products (OJ No.L241
P27-28) defines the different performance classes for building products excluding floorings
and, separately, floorings. The relevant test methods for determining the performance are
being prepared by CEN/TC127.
Safety warning
The attention of all persons concerned with managing and carrying out the tests described in
this standard is drawn to the fact that fire testing can be hazardous and that toxic and/or
harmful smoke and gases can be produced during the test.
An assessment of all potential hazards and risks to health should be made and safety
precautions should be identified and provided. Smoke and gases should be removed from the
workplace. Written safety instructions should be issued. Appropriate training should be given
to relevant personnel. Laboratory personnel should ensure that they follow written safety
instructions at all times.
Special precautions are required for the propane gas supply system.

The equipment, for example tubes, couplings, flow meters, should be approved for
propane.

The burner should be equipped with a remote-controlled ignition device, for example a
pilot flame or a glow wire. There should be a warning system for leaking gas and a valve
for immediate and automatic cut-off of the gas supply in case of extinction of the ignition
flame. The pilot flames can be ignited directly by an operator in the test room, however,
no one should be present in the test room during ignition of a burner.

It should be possible to operate the switch between auxiliary and main burner and the
preceding main valve (to open or stop the propane supply) from outside the test room.
Special precautions are required for the extinction of burning specimens.
When the extinction is carried out because of intensive combustion of the specimens, it is
recommended that a second operator is ready to intervene. Means for extinguishing should
be available (e.g. since the heat output during intensive combustion can damage the
apparatus).
1 Scope
This European Standard specifies a method of test for determining the reaction to fire
performance of construction products excluding floorings, and excluding products which are
indicated in the EC Decision 2000/147/EC, when exposed to thermal attack by a single
burning item (SBI). The calculation procedures are given in annex A. Information on the
precision of the test method is given in annex B. The calibration procedures are given in
annexes C and D, of which C is a normative annex.
NOTE This European Standard has been developed to determine the reaction to fire performance
of essentially flat products. The treatment of some families of products, e.g. linear products (pipes,
ducts, cables etc) can need special rules.

4 Test facility
4.1 General
The SBI test facility shall consist of a test room, the test apparatus (trolley, frame, burners,
hood, collector and ducting), the smoke exhaust system and general measuring equipment.
These components are specified in 4.2 to 4.7. Design drawings are given in annex E.
Dimensions given in the drawings are nominal unless tolerances are given in the text.
NOTE The air supply to the test room entering below the trolley should be fresh, uncontaminated
air.
4.2 Test room
4.2.1 The test room shall have an inner height of (2,4  0,1) m and an inner floor area of
(3,0  0,2) m in both directions. The walls shall be made of stone type building blocks (e.g.
cellular concrete), gypsum boards, calcium silicate boards or other boards classified as
Euroclass A1 or A2.
4.2.2 One wall of the test room shall have an opening to insert the trolley from the
surrounding laboratory into the test room. The opening shall be at least 1 470 mm wide and
2 450 mm high (dimensions of the frame). Windows shall be placed in the two walls facing the
front side of the two perpendicular specimen planes. To be able to handle the SBI apparatus
and the specimen when the trolley is in place, an additional door is needed.
4.2.3 With the trolley in place in the test room, the distance between the long wing
specimen surface touching the U-profile and the wall of the test room shall be (2,1  0,1) m.
This distance shall be measured perpendicularly to the wall facing the long wing. The areas of
the openings in the test room, excluding the air inlet at the bottom of the trolley and the smoke
exhaust opening in the hood, shall not exceed a total of 0,05 m .
4.2.4 Both left-orientated arrangements, as shown in Figure 1, and right-orientated
arrangements (the trolley shown in Figure 1 mirrored around a vertical line) are allowed.
NOTE 1  To be able to remove side plates of the hood without removing the collector, attention should
be paid to the co
