1 Scope This 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 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, therein, the pipe heat insulation materials shall adopt the methods specified in Annex H. 2 Normative References The following normative documents contain provisions which, through reference in this standard, constitute provisions of this standard. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest editions of these documents are applicable. For undated references, the latest edition of the normative document referred to applies. GB/T 16839.1 Thermocouples-Part 1: Reference Tables (GB/T 16839.1, idt IEC 584-1:1995). GB/T 6379.1-2004 Accuracy (Trueness and Precision) of Measurement Methods and Results-Part 1: General Principles and Definitions (ISO 5725-1: 1994, IDT) GB/T 6379.2-2004 Accuracy (Trueness and Precision) of Measurement Methods and Results-Part 2: Basic Method for the Determination of Repeatability and Reproducibility of a Standard Measurement Method (ISO 5725-2: 1994, IDT) ISO 13943 Fire Safety-Vocabulary EN 13501-1 Fire Classification of Construction Products and Building Elements-Part 1: Classification Using Test Data from Reaction to Fire Tests EN 13238 Reaction to Fire Test for Building Products-Conditioning Procedures and General Rules for Selection of Substrates 3 Terms and Definitions For the purposes of this standard, the terms and definitions in ISO 13943 and EN 13501-1 apply, together with the following. 3.1 Backing board Calcium silicate panel used to back the specimen that can be placed directly against a free-standing test specimen or at a distance from it. 3.2 Specimen Piece of a product, which is to be tested. Note: This can include the mounting technique used in its end-use application. This also can include an air gap and/or a substrate where appropriate. 3.3 Substrate Product which is used immediately beneath the product about which information is required. 3.4 THR600s Total heat release from the specimen in the first 600s of exposure to the main burner flames. 3.5 LFS Lateral flame spread on the long specimen wing. Note: The LFS is defined in more detail in 8.3.3. 3.6 TSP600s Total smoke production from the specimen in the first 600 s of exposure to the main burner flames. 3.7 FIGRA0.2 MJ Maximum of the quotient of heat release rate from the specimen and the time of its occurrence using a THR-threshold of 0.2 MJ. Note: The FIGRA0.2 MJ is described in more detail in A.5.3. 3.8 FIGRA0.4 MJ Maximum of the quotient of heat release rate from the specimen and the time of its occurrence using a THR threshold of 0.4 MJ. Note: The FIGRA0.4 MJ is described in more detail in A.5.3. 3.9 SMOGRA Smoke growth rate. The maximum of the quotient of smoke production rate from the specimen and the time of its occurrence. Note: The SMOGRA is described in more detail in A.6.3. 3.10 Sustained flaming Persistence of flame on or over a surface for a minimum period of time. 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 1470mm wide and 2450mm 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 0.05m2. 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.
