1、Designation: D4151 10D4151 18Standard Test Method forFlammability of Blankets1This standard is issued under the fixed designation D4151; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenth
2、eses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method provides a means to identify blanket fabrics which ignite easily and propagate flame across the surface.1.2 This test method specifies
3、the procedures described in the “Voluntary Blanket Flammability Standard” which has been usedby the blanket industry in the United States since 1972.1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame undercontrolled conditions, but
4、does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials,products or assemblies under actual fire conditions.NOTE 1This test method is not identical to 16 CFR Part 1610, Flammability of Clothing Textiles.

13、TM standard an indication of what changes have been made to the previous version. Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current versionof the standard as published

16、 terms used in this test method, refer to Terminology D123.4. Summary of Test Method4.1 Specimens cut from the blanket fabric are prepared by brushing if they have a raised fiber surface and by drying. The driedspecimen is held in a special apparatus, a standardized flame is applied to the surface f
17、or a specified time under controlledconditions, and burning, charring, or discoloration of a paper monitor is noted. Two classes of flammability are described.4.1.1 Aburn of sufficient intensity to discolor a paper monitor in specified contact with the surface of the test specimen indicatesignition
18、of the blanket surface (see 11.4.1).5. Significance and Use5.1 This test method for the determination of the flammability of blankets is considered satisfactory for acceptance testing ofcommercial shipments of blankets since this test method has been used extensively in the trade for acceptance test
19、ing.5.2 This test method is used to evaluate electric blanket fabric, but tests should be performed on the fabric itself intended toevaluate fabrics used in electric blankets without the resistance heating wires inserted.wires.5.3 All fabrics made of natural or regenerated cellulose, as well as many
20、 made from other natural or synthetic fibers, arecombustible. Some combustible Fabrics are potentially combustible. Some fabrics when used for blankets are potentiallydangerous to the user because ofdepending on the ease of ignition, rapidity, and intensity of burning. The first characteristic canbe
21、 judged with the aid of the flammability tester.This test method addresses some of these characteristics.6. Apparatus and Materials6.1 Flammability Tester, as shown in Figs. 1-4 and described in A1.1.1, A1.1.2, and A1.1.9 of Test Method D1230.6.1.1 The test cabinet shall be equipped with a system to
22、 control the time of flame impingment on the specimen to 1 6 0.05s. A system found to be suitable is:6.1.1.1 Adjustable electronic timer controlling a burner solenoid to activate the burner mechanism.FIG. 1 Flammability TesterD4151 1826.1.1.2 Electronic Counter (digital clock reading to 0.01 s), sta
23、rted by a switch that is activated by the burner mechanism whenthe burner is in the position to impinge flame on the specimen and is stopped when the burner retracts from the specimen.FIG. 2 Flammability Tester (Cabinet Details)FIG. 3 Flammability Tester (Additional Cabinet Details)D4151 183NOTE 3A
24、flammability tester made for use in Test Method D1230 has to be modified when used with Test Method D4151 by changing the burner,specimen holder, and timing mechanism.6.2 Specimen Holder and Base, as shown in Figs. 5 and 6.FIG. 4 Flammability Tester ArrangementFIG. 5 Specimen Holder AssemblyD4151 18
