Summ

23、ary of Test Method4.1 Sewing thread is evaluated for break strength before andafter exposure to air at an elevated temperature.4.2 Flame resistance of edge binding tape is determined bychar length measurements.4.3 Specimens of fire barrier fabrics which are securedusing sewing thread and edge bindin

Significance and Use5.1 Evaluation of raw material components is a vital andongoing part of any manufacturing operation, especially wheneach item can contribute to the technical performance of thefinal product.5.2 Thi

25、s test method measures the behavior of mattress edgebinding and sewing thread during and after exposure to an openflame ignition source.5.3 Flame resistance of the components used to close theperimeter of a mattress is an important factor in limiting thepotential of a bedding fire by preventing the

26、chance for seamfailure.5.4 Data which show a correlation of behavior for both thesewing thread and edge binding tape, when tested as asubassembly according to this test method, and also whentested using a full scale composite mattress burn test, such asCalifornia TB 603, can provide the manufacturer

27、 with impor-tant information. These data can be valuable when selectingcomponents to be used in the manufacture of its productswhich are designed to use mattress edge binding and sewingthread.5.5 The level of performance required for these componentsis (1) that they do not support the afterflame, an

28、d (2) that thesecomponents demonstrate post flame exposure characteristicswhich contribute to retaining the structural integrity of thesubassembly.5.6 In case of a dispute arising from differences in reportedresults when using this test method for acceptance testing ofcommercial shipments, the purch

29、aser and the supplier shouldconduct comparative tests to determine if there is a statisticalbias between their laboratories. Competent statistical assis-tance is recommended for the investigation of bias. As aminimum, the two parties should take a group of test speci-mens which are as homogeneous as

30、 possible and which arefrom a lot of material of the type in question. The testspecimens should then be sent to each laboratory for testing.The average results from the two laboratories should becompared using Students t-test and an acceptable probabilitylevel chosen by the two parties before testin

31、g is begun. If a biasis found, either its cause must be found and corrected or thepurchaser and the supplier must agree to interpret future testresults with consideration to the known bias.3American Association of Textile Colorists and Chemists, PO Box 12215,Research Triangle Park, NC 27709.Availabl

Subassembly8.1 Select a fire barrier fabric which has been tested usingTest Method D7140.88.1.1 Make samples using the sewing thread shown tocomply to Section 5 and edge binding tape shown to comply toSection 6.8.1.1.1 Select the edge binding tape havin

One section shall repre-sent the fire barrier fabric used on the top panel of the mattress;one section shall represent the fire barrier fabric used on theside panel of the mattress.8.1.2.1 Sew the fa

42、bric sections together using the sameseam closing techniques used to manufacture mattresses.7The time and temperature requirements of Test Method 1534 were developedusing data originally developed by the U.S.Air Force in 1968. These data were usedto determine the melting point of synthetic fibers wh

43、ich would be made into yarnsfor fabrics and sewing threads and then used to manufacture protective clothingworn by military pilots, tank crew personnel, shipboard personnel, and space suitsworn by astronauts. The testing threshold used to evaluate fibers was established asa benchmark for a wide arra

44、y of textile products. Sewing threads which melt whenexposed to high temperatures do not demonstrate any retained break strength. Thosesewing threads which are able to withstand exposure at this elevated temperatureretain measurable strength characteristics between 65 to 85 % of the original breakst

45、rength.8Fire barrier fabrics are made using a variety of technologies. In addition tofabrics made of inherently flame resistant fibers, these structures can be made ofmultifiber hybrids and also treated fabrics. The fabrics are manufactured as bothwoven and nonwoven structures. The synergy of the se

46、wing thread and edge bindingtape is intended to work in conjunction with every type of fire barrier fabric whichcan be used to successfully pass the requirements of an open flame test, such asTechnical Bulletin 603.FIG. 1 Mattress Edge Bound SampleFront ViewD7016/D7016M 0938.1.3 Samples measure a mi

The seam with the mattress edge bindingshould be horizontal and approximately midway between thetop and bottom edge.8.2.3 When evaluating specimens which are made using afire barrier fabric, dress cover fabric, and foam, remove thefoam layer except for that foam which is encapsulated by theedge binding and sewing thread. (See Figs. 4-6.)98.2.3.1 The perimeter of cut specimens which have anunfinished raw edge shall be finished using the same sewingthread as evaluated in Section 5.
