1.1 This test method measures the flammability characteristics of mattress edge bindings and sewing threads during and after exposure to an open flame ignition source. 1.1.1 This test method is used to evaluate these components either independently or in combination for use in mattresses designed with a fire barrier fabric. 1.1.1.1 The test method is used to evaluate mattress edge binding and sewing thread when the design requires the use of these components. 1.1.2 This test method can be used as a screening test method to determine how sewing thread and mattress edge binding component combinations will perform. 1.2 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but 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. 1.3 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method evaluates the edge binding assembly used to determine how well the two external elements along the mattress edge, essentially, the edge tape and FR sewing thread, behave after exposure to an open flame and a hot air oven. These data can be used to confirm that either the mattress or foundation, or both will pass when tested using 16 CFR1633. Evaluation of raw material components is a vital and ongoing part of any manufacturing operation, especially when each item can contribute to the technical performance of the final product. 5.2 Inherently flame resistant (FR) sewing thread is used as shown in Fig. 1 , Fig. 2 , and Fig. 3 to secure and encapsulate the following elements: FIG. 1 Mattress Edge Bound Sample – Profile FIG. 2 Before Trimming – Profile FIG. 3 After Trimming – Profile 5.2.1 Test method measures the behavior of mattress edge binding tape that joins and closes the assembly of either the mattress or the box spring foundation, or both, and sewing thread during and after exposure to an open flame ignition source. 5.2.2 Test method can be used to determine if the encapsulated multilayer assembly of mattress cover, fire barrier, and foam (when used) work together to prevent entry of open flame to mattress interior. 5.3 Flame resistance of the components used to close the perimeter of a mattress is an important factor in limiting the potential of a bedding fire by preventing the chance for seam failure. 5.4 Data which show a correlation of behavior for both the sewing thread and edge binding tape, when tested as a subassembly according to this test method, and also when tested using a full scale composite mattress burn test, such as 16 CFR 1633, can provide the manufacturer with important information. These data can be valuable when selecting components to be used in the manufacture of its products which are designed to use mattress edge binding and sewing thread. 5.5 The level of performance required for these components is (1) that they do not support the afterflame, and (2) that these components demonstrate post flame exposure characteristics which contribute to retaining the structural integrity of the subassembly. 5.6 In case of a dispute arising from differences in reported results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. The test specimens should then be sent to each laboratory for testing. The average results from the two laboratories should be compared using Student's t -test and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results with consideration of known bias.
