29、ruction 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
30、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 a
31、nd 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
32、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
33、 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
34、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 i
35、ntensive 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). Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 12/01/2011 06:54
36、, Uncontrolled Copy, (c) BSIBS EN 13823:2010EN 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, w
37、hen 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 ha
38、s 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 appli
