| Significance and Use | ||||||||
|
5.1?This test method determines the response of textiles to a standard ignition source, deriving measurement values for afterflame time, afterglow time, and char length. 5.2?The vertical flame resistance, as determined by this test method, only relates to a specified flame exposure and application time. 5.3?This test method maintains the specimen in a static, draft-free, vertical position and does not involve movement except that resulting from the exposure. 5.4?Test Method D6413 has been adopted from Federal Test Standard No. 191A method 5903.1, which has been used for many years in acceptance testing. The between-laboratory precision of this test method has not been established. Refer to Section 14 for single-laboratory precision. 5.4.1?If there are differences or practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, the test samples used should be as homogeneous as possible, that are drawn from the material from which the disparate test results are obtained, and that are assigned randomly in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration on the known bias. |

1.1?This test method is used to measure the vertical flame resistance of textiles. 1.1.1?As a part of the measure of flame resistance, afterflame and afterglow characteristics are evaluated. 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 is inherently hazardous. 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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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. |
