EN 13823:2010 (E) 4 Foreword This document (EN 13823:2010) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buidlings”f 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of an identical text or by endorsement, at the latest by January 2011, and conflicting national standards shall be withdrawn at the latest by January 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13823:2002. 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 European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 13823:2010 (E) 5 Introduction The classification of the reaction to fire performance of construction products established by EC Decision 2000/147/EC (OJEU L50 of 23.2.2000) defines in Table 1 the reaction to fire classes for building products excluding floorings. The relevant test methods for determining the reaction to fire are being prepared by CEN/TC 127. 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 (primary) 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). SIST EN 13823:2011



EN 13823:2010 (E) 6 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 Table 1 of 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

FprEN 13823:2009 (E) 4 Foreword This document (FprEN 13823:2009) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buidlings”f the secretariat of which is held by BSI. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 13823:2002. 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 Council Directive 89/106/EEC. kSIST FprEN 13823:2010



FprEN 13823:2009 (E) 5 Introduction The classification of the reaction to fire performance of construction products established by EC Decision 2000/147/EC (OJEU L50 of 23.2.2000) defines in Table 1 the reaction to fire classes for building products excluding floorings. The relevant test methods for determining the reaction to fire are being prepared by CEN/TC 127. 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 (primary) 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). kSIST FprEN 13823:2010



FprEN 13823:2009 (E) 6 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 Table 1 of 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

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
0,05) m and an inner floor area of (3,0
0,05) 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 class 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 kSIST FprEN 13823:2010



FprEN 13823:2009 (E) 8 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
0,05) 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 m2. 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 connection between the frame of the SBI apparatus and the ceiling of the room. It should be possible to move the side plate outwards at the bottom. NOTE 2 The relative position of the frame in the test room depends on the details of the connection between room and frame. kSIST FprEN 13823:2010
