8、ish Standard has been prepared by Subcommittee FSH/2/13 and is the English language version of EN 1869 : 1997 Fire blankets published by the European Committee for Standardization (CEN). EN 1869 was produced as a result of international discussion in which the United Kingdom took an active part. EN
9、1869 : 1997 supersedes the requirements of BS 6575 : 1985 covering light-duty fire blankets. The scope of BS 6575 : 1985 is currently being revised to cover heavy-duty fire blankets only. On publication of the revised standard, BS 6575 : 1985 will be withdrawn. Compliance with a British Standard doe

21、of materials which meet 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 perfor
22、mance requirements specified 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-usea
23、ble and that are intended 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 d
24、efinition applies. Fire 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
25、are stitched together. 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
26、not become detached 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
27、 of being rolled completely 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, unfo
28、lded, and held ready 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
29、 fray or tear during 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 (3455) mm diameter tray, see figure C.1 for details. 4.2 The fir
30、e blanket shall remain 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 w
31、hite lettering on a 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
32、 instruction to cover 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
33、by metres. d) Folding instructions.

34、us Commission, Via Del Terme Di Caracalla 1-00100 Roma, Italy. Annex A (normative) Test requirements A.1 Except where otherwise specified, tests shall be carried out at a temperature of (2010) C. A.2 All tests shall be carried out using a single thickness of the fire blanket. Each fire blanket shall
35、 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 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 (2010) C, at a relative humidity of
36、 (6010) % for 48 h before testing. After this period of time, the fire blanket shall not be exposed to a different atmosphere 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 (no
37、rmative) Electrical resistance test B.1 Principle The electrical resistance of the blanket fabric is measured between a negative 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 electr
38、ode. B.2.2 Megohmeter 500 V d.c. B.2.3 Flat conducting rectangular plate, 450 mm 3 150 mm incorporating an insulated handle and having a total mass of (5,00,25) 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
39、 table and measure its electrical resistance using the megohmeter in accordance with the manufacturers instructions. Move the 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 precaution
40、s to safeguard the health of personnel conducting the test against the risk of fire, spillage of the hot oil and the inhalation 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 temper
41、ature 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 conforms 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 (3455) mm and depth (1005) mm, and free from residue fr
42、om 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.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 dis
43、tance from one of the other sides to the far edge of the tray is (6505) mm. See figure C.1. C.2.2 The fire performance test 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 temperatu
44、re 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 the 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 b
45、urn freely for 2 min after ignition, and then position the fire blanket fully opened over the tray, so that the centre point 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 mi
46、n after ignition and observe whether the fire is extinguished. The fire is considered to be extinguished if there are: no 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 exti
47、nguished and not merely starved of fuel.
