19、eet the performance requirements of this standard. A test for electrical resistance of the complete fire blanket is given to ensure that in the event of use where live electrical equipment is concerned, the potential for an electrical shock is minimized. In addition to the performance requirements s

20、pecified in this standard it is recommended that fire blankets be suitably treated where necessary to give adequate resistance to attack by micro-organisms and insects throughout the design life. 1 Scope This standard specifies requirements for fire blankets which are not re-useable and that are int

21、ended for use by one person. It is applicable to fire blankets primarily intended for extinguishing cooking oil fires. NOTE. It is anticipated that they can also be used on fires involving personal clothing. 2 Definitions For the purposes of this European Standard the following definition applies. F

22、ire blanket A flexible sheet of material intended to be used to extinguish small fires by smothering. 3 Construction 3.1 A fire blanket shall be formed of one sheet of material, or two or more sheets of material each of a size equal to the overall size of the fire blanket, which are stitched togethe

23、r. The two sides shall be similar in performance. There shall be no seams in the fire blanket except as follows if required: a) where the hand-holding devices are fixed; and b) at any edge. 3.2 Hand holding devices shall not comprise loops, they shall not be flammable, and shall not become detached

24、from the fire blanket during any of the testing specified in this standard. 3.3 Fire blankets shall be rectangular or square and no edge shall be less than 0,9 m or more than 1,8 m. 3.4 The total mass of any fire blanket shall not exceed 4,5 kg. 3.5 Fire blankets shall be capable of being rolled com

25、pletely around a (50 + 2) mm diameter bar, and along any axes parallel to adjacent sides, without permanent deformation. 3.6 When stowed or packed in accordance with the manufacturers instructions, it shall be possible for a fire blanket to be taken from the stowed position, unfolded, and held ready

26、 for use in not more than 4 s. The force required to remove the fire blanket shall not exceed 80 N. 3.7 When tested in accordance with annex B, the electrical resistance of the blanket material shall be not less than 1 MV at any point. 3.8 The edges of the fire blankets shall not fray or tear during

27、 any of the tests specified in annexes A to C. 4 Fire performance 4.1 When tested in accordance with annex C, the fire blanket shall be capable of extinguishing the cooking oil fire as described in annex C using the (345 5) mm diameter tray, see figure C.1 for details. 4.2 The fire blanket shall rem

28、ain whole and not ignite during the test. 5 Marking 5.1 Each blanket shall be indelibly marked with the manufacturers or suppliers name and address, the number EN 1869 and year of this standard and the model or type number. 5.2 The container shall be marked with the following in white lettering on a

29、 red background. These markings shall be visible when the container is fixed in position. a) The words FIRE BLANKET in letters not less than 20 mm high. b) Model or type number. c) The instruction DISCARD AFTER USE. d) Instructions for use incorporating pictograms and including an instruction to cov

30、er burning material completely, switch off heat and leave covered until cool. 5.3 Either the reverse of the container or a leaflet shall be marked with the following. a) The number of this European Standard. b) Instructions prescribing an annual service. c) Blanket size in metres by metres. d) Foldi

31、ng instructions.Page 4 EN 1869 : 1997 BSI 1997 1) Published by the Joint Food and Agricultural Organization of the United Nations/World Health Organization, Codex Alimentarius Commission, Via Del Terme Di Caracalla 1-00100 Roma, Italy. Annex A (normative) Test requirements A.1 Except where otherwise

32、 specified, tests shall be carried out at a temperature of (20 10) C. A.2 All tests shall be carried out using a single thickness of the fire blanket. Each fire blanket shall be tested separately. A.3 A minimum of three fire blankets shall be tested. Identify and mark the blankets as 1 to 3 and the

33、two sides as a or b. Two of the blankets shall be tested on side a, and one on side b. A.4 The fire blanket shall be conditioned in air at (20 10) C, at a relative humidity of (60 10) % for 48 h before testing. After this period of time, the fire blanket shall not be exposed to a different atmospher

34、e for more than 5 min. A.5 The fire blankets shall be stored for testing in their containers or stowage position for a minimum of 24 h immediately prior to testing. Annex B (normative) Electrical resistance test B.1 Principle The electrical resistance of the blanket fabric is measured between a nega

35、tive electrode formed by a metal table top and positive electrode formed by a flat rectangular conducting plate. B.2 Apparatus B.2.1 Table, with metal top to be negative electrode. B.2.2 Megohmeter 500 V d.c. B.2.3 Flat conducting rectangular plate, 450 mm3 150 mm incorporating an insulated handle a

36、nd having a total mass of (5,0 0,25) kg. NOTE. A stainless steel plate will be adequate. B.3 Procedure Arrange the apparatus as shown in figure B.1. Lay the blanket flat on the table and measure its electrical resistance using the megohmeter in accordance with the manufacturers instructions. Move th

37、e electrode and blanket as necessary to test the whole of the blanket. Annex C (normative) Fire performance test NOTE. Attention is drawn to the necessity for taking precautions to safeguard the health of personnel conducting the test against the risk of fire, spillage of the hot oil and the inhalat

38、ion of smoke or toxic products of combustion. C.1 Materials and apparatus C.1.1 Fuel. The fuel shall be an edible cooking oil, free from additives, with an auto-ignition temperature in the range of 350 C to 370 C. 3 l of fresh fuel shall be used for each test. NOTE. Edible Soya bean oil which confor

39、ms to CODEX STAN 20-1981 or a Rapeseed oil which conforms to CODEX STAN 24-1981. 1) C.1.2 Fuel tray, of internal diameter (345 5) mm and depth (100 5) mm, and free from residue from previous tests. C.1.3 Table, 0,8 m high, and larger than the fire blanket size. C.1.4 Tray support stand, see figure C

40、.1. C.2 Procedure C.2.1 Place the test tray centrally on the tray support stand, which shall itself be placed on the table equidistant from two opposite sides, and so that the distance from one of the other sides to the far edge of the tray is (650 5) mm. See figure C.1. C.2.2 The fire performance t

41、est shall be conducted in a room free from draughts, and with sufficient ventilation to allow the fire to develop freely and to remove products of combustion. The ambient temperature shall be between 0 C and 30 C. C.2.3 Place the fuel in the tray and, using a gas burner centrally positioned under th

42、e tray, heat the oil so that its temperature, measured centrally, increases at about 10 C/min and self-ignites within 25 min to 35 min. Turn off the gas supply. Allow the fire to burn freely for 2 min after ignition, and then position the fire blanket fully opened over the tray, so that the centre p

43、oint of the fire blanket is close to the centre of the tray. Subsequently adjust the position of the blanket as seems necessary from any side of the table. Remove the blanket 17 min after ignition and observe whether the fire is extinguished. The fire is considered to be extinguished if there are: n

44、o visible flames after removal of the blanket; and no re-ignition within 3 min of removal of the blanket. Some fuel shall remain at the end of the test, i.e. the fire shall be extinguished and not merely starved of fuel. Annex D (informative) Bibliography CODEX STAN: 20-1981 Codex standard for edibl
