20、ISO 9239 provide a basis for estimating one aspect of fire exposure behaviour of floorings. The imposed radiant flux simulates the thermal radiation levels likely to impinge on the floor of a corridor whose upper surfaces are heated by flames or hot gases or both, during the early stages of a develo

21、ping fire in an adjacent room or compartment under wind-opposed flame-spread conditions. DIN EN ISO 9239-1:2010-11 EN ISO 9239-1:2010 (E) 4 WARNING The possibility of a gas-air fuel explosion in the test chamber should be recognized. Suitable safeguards consistent with sound engineering practice sho

22、uld be installed in the panel fuel supply system. These should include at least the following: a gas-feed cut-off which is immediately activated when air and/or gas supply fail; a temperature sensor or a flame detection unit directed at the panel surface that stops fuel flow when the panel flame goe

23、s out. The attention of all persons concerned with managing and carrying out this test is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful gases may be evolved during the test. Operational hazards may also arise during the testing of spec

24、imens, such as the possibility of an explosion, and during the disposal of test residues. An assessment of all the potential hazards and risks to health should be made and safety precautions should be identified and provided. Written safety instructions should be issued. Appropriate training should

25、be given to relevant personnel. Laboratory personnel should ensure that they follow written instructions at all times. 1 Scope This part of ISO 9239 specifies a method for assessing the wind-opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radian

26、t gradient in a test chamber, when ignited with pilot flames. Annex A gives details of assessing the smoke development, when required. This method is applicable to all types of flooring, e.g. textile carpet, cork, wood, rubber and plastics coverings as well as coatings. Results obtained by this meth

27、od reflect the performance of the flooring, including any substrate if used. Modifications of the backing, bonding to a substrate, underlay or other changes of the flooring may affect test results. This part of ISO 9239 is applicable to the measurement and description of the properties of floorings

28、in response to heat and flame under controlled laboratory conditions. It should not be used alone to describe or appraise the fire hazard or fire risk of floorings under actual fire conditions. Information on the precision of the test method is given in Annex B. DIN EN ISO 9239-1:2010-11 EN ISO 9239

38、d radiant panel inclined at 30 where it is exposed to a defined heat flux. A pilot flame is applied to the hotter end of the specimen. The test principle is illustrated in Figure 1. Following ignition, any flame front which develops is noted and a record is made of the progression of the flame front
