20、lame but the commitke consider that this should not restrict the use, for the purposes described here, of materials which meet the performance requirements of this siandard A test for electrid resistance of the complete fire blanket is given to ensure that in the event of use where live electrical e

21、quipment is concerned, the potential for an electrical shock is minimized. in addition to the performance requirements specified in this standard it is recommended that re blankets be suitably treated where necessary to give adequate resistance to attack by micro-organisms and insects throughout the

22、 design Me. 1 scope This standard specifies requirements for re blankets which are not re-useable and that are intended for use by one person. It is applicable to fire blankets primarily intended for extinguishmg cooking oil fres. NUE. It is anticipated that they can also be used on fires involving

23、personal clotung. 2 Definitions For the purposes of this European standard the foiiowing definiton applies. Fire blanket A flexible sheet of material intended to be used to extinguish smal fires by smothering. 3 Construction 3.1 A fire blanket shall be formed of one sheet of maeriai, or two or more

24、sheets of material each of a size equal to the overall size of the fire blanket, which 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 xd, and b) at any edge. 3.2 Han

25、d holding devices shall not comprise loops, they shall not be flammable, and shall not become detached from the fire blanket during any of the testing specified in this standard. 3.3 Fire blankets shal be rectangular or square and no edge shal be less than 0,9 m or more than 1,8 m. 3.4 The total mas

26、s of any fire blanket shail not exceed 4,5 kg. Page 3 EN 1869 : 1997 36 Fire blankets shali be capable of bei rolled completely around a (50 + 2) mm diameter bar, and along any axes parallel to eacent sides, without permanent deformation. 3.6 When stowed or packed in accordance with the manufacturer

27、s instnictions, it shall be possible for a fire blanket to be taken from the stowed position, unfolded, and held ready for use in not more than 4 s. The force required to remove the ire blanket sha not exceed 80 N. 3.7 When tested in accordance with annex B, the electrical resistance of the blanket

28、material shall be not less than 1 Mil at any point. 3.8 The edges of the fire blankets shall not 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 extinguishuig the cookjng oilfreasdes

29、cribedinannexCusingthe (345f5)mm diameter tray, see figure C.l for details. 4.2 The fire blanket shall remain whole and not ignite during the test. 6 Marking 6.1 Each blanket shal be indelibly marked with the mufacturers or suppliers name and address, the number EN 1869 and year of this standard and

30、 the model or type number. 6.2 The container shal be marked with the following in white lettering on a red background. These markings shall be visible when the container is xed in position. a) The words FIRE BLANKET in letters not less b) Model or type number. c) The instruction DISCARD AF”IER USE.

33、s shall be carried out at a temperatwe of (20 f 10) “C. A2 Ail tests shall be carried out using a single thickness of the re blanket. Each re blanket shall be testedseparately. A3 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. T

34、wo of the blankets shail be tested on side a, and one on side b. A.4 The fire blanket shali be conditioned in air at (20 f 10) OC, at a relative humidity of (60 f 10) % for 48 h before testing. After this period of time, the re blanket shail not be exposed to a dinerent atmosphere for more than 5 mi

35、n. A6 The fie blankets shall be stored for testing in their containem or stowage position for a minimum of 24 h immediately prior to testing. Annex B (normative) Electrical resistance test B.l Principle The electrid resistance of the blanket fabric is measured between a negative eleclmde formed by a

36、 metai table top and positive electrode formed by a fiat rectangular conducting plate. B.2 Apparatus B.2.1 Tdk, with metai top to be negative electrode. B.2.2 Megohmeer 500 V d.c. B.2.3 fit conducting rectangular plute, 450 mm X 150 mm incorporating an insdated handle and having a total mas of (5,O

37、f 0,26) kg. B.3 Procedure Arrange the apparatus as shown in fgure B.l. Lay the blanket flat on the table and measure its electrical resistance using the megohmeter in accordance with the manufacturers hsbuctions. Move the electrode and blanket as necessary to test the whole of the blanket. NOTE. A s

38、talliless steel plate wiii be aequate. Annex C (normative) Fire performance test NOTE. Atention is drawn to the necessity for taking precautions to safeguard the health of personnel conducting the test against the risk of re, spillage of the hot oil and the inhalation of smoke or toxic products of c

39、ombustion. C.l Materials and apparatus C.l.l M. The fuel shall be an edible cooking oil, free from additives, with an auto-ignition temperature in the range of 350 OC to 370 OC. 3 1 of fresh fuel shall be used for each test. NOTE. Edible Soya bean oil which conforms to CODEX STAN 20-1981 or a Rapese

40、ed oil which conforms to CODEX STAN 241981.) C.1.2 Fue+? trug of internal diameter (345f5) mm and depth (100 f 5) mm, and free from residue from previous tests. C.1.3 Tdk, 0,8 m high, and wer than the fire blanket size. C.1.4 Tray support stand, see figure C.1. C.2 Procedure C.2.1 Place the test tra

41、y cenWy on the tray support stand, which shal 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 f 5) mm. See figure C.1. C.2.2 The fire performance test shall be conducted in a room free from dr

42、aughts, and with sufficient ventilation to allow the fire to develop freely and to remove products of combustion. The ambient temperature shall be between O “C and 30 OC. C.2.3 Place the fuel in the tray and, using a gas burner centdly positioned under the m, heat the oil so that its temperature, me

43、asured centsally, increases at about 10 “CM and self-ignites wihh 25 min to 35 min Turn off the gas supply. Allow the h-e to burn freely for 2 min after ignition, and then position the re blanket fully opened over the tray, so that the centre point of the fire blanket is close to the centre of the t

44、ray. Subsequently aust 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: - no visible flames after removai of the blanket; and - no

45、reignition within 3 min of removal of the blanket. Some fuel shail remain at the end of the test, Le. the fire shall be extjnguished and not merely starved of fuel.
