5、 appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2. Terminology2.1 Definitions For the purpose of this specification, thefollowing definition applies:2.1.1 fire blanket, nflexible sheet(s) of material intendedto be used to extinguish sma
6、ll fires by smothering.3. Physical Properties3.1 Size and ShapeCooking fire suppression blankets shallbe rectangular or square, with no edge less than 0.91 6 0.05 m(36 6 2 in.).3.2 MassCooking fire suppression blankets shall have amass not exceeding 2 kg (4.4 lb).3.3 Hand Holding Devices:3.3.1 Hand
7、holding devices, if provided, shall consist ofsewn in straps on both sides of the blanket to facilitate quickrelease. The strap length shall not be less than 100 mm (3.9 in.)or more than 200 mm (7.8 in.) in length, and easily grasped andreleased when applying the blanket over a cooking fire. Thestra
8、ps may be made of any high strength material and shall beof contrasting color from the blanket itself.3.3.2 Attention shall be paid to the design of any holdingdevice to ensure ease of handling and hand release.3.4 Appearance and Bi-Lateral UseThe two sides of a fireblanket shall be of identical app
9、earance, finish or color andshall give the equivalent results when tested for compliancewith Section 4.NOTE 1It is important not only that either side of fire blanket can beexposed to the fire or other hazard with equal effectiveness, but also thatno doubt be created in the mind of the user at the m
10、oment of emergencyuse as to which side of the fire blanket to apply to the hazard.3.5 Resistance to Fraying or TearingThe edges of cook-ing fire suppression blankets shall not fray or tear duringtesting for compliance with 4.3.1, 4.3.2, 4.4.4, and 4.5.1.5.4. Test Methods4.1 Sampling and Sequence of
11、Testing:4.1.1 A minimum of nine cooking fire suppression blanketsis required. Identify and mark the cooking fire suppressionblankets as No. 1 to 9 and the two sides as (a) and (b).4.1.1.1 Cooking fire suppression blankets which contain aseam shall be tested both on and off the seam and, where thesea
12、m is tested, in the most unfavorable condition. Tests shall becarried out using a single thickness of cooking fire suppressionblankets.4.1.2 Use any fire blanket as required for the nondestructiveexaminations required in Section 4. Use cooking fire suppres-sion blankets No. 1, 2, and 3 for testing t
13、o 4.5.1 in the sequenceof 1(a), 2(b), 3(a). Use cooking fire suppression blankets 4, 5and 6 for testing to 4.4 in sequence of 4(a), 5(b), and 6(a). Usecooking fire suppression blankets 7, 8 and 9 for testing to 4.5.2in sequence of 7(a), 8(b), and 9(a).4.2 Conditioning:4.2.1 Condition cooking fire su
14、ppression blankets for test-ing for 48 h so that they are in equilibrium with air at 20 6 5Cand at a relative humidity of 50 to 70 %. After conditioning, donot expose the blanket to air at different temperature or relativehumidity for longer than 5 min before testing. Keep the fireblanket in a seale
15、d plastic bag or other conditioning containeruntil testing if it is necessary to transport it any distance to thetest site.1This specification is under the jurisdiction of ASTM Committee F15 onConsumer Products and is the direct responsibility of Subcommittee F15.46 on FireSuppression Towels.Current
