Standard Test Method for Determining the Flammability Characteristics of Nonrigid Solid Plastics
SIGNIFICANCE AND USE
5.1 The test results represent the afterflame and afterglow times, in seconds, for a material under the conditions of the test.
5.2 The afterflame and afterglow times and other burning phenomena will vary with thickness. Test data shall only be compared with data for material of the same comparable thickness.
5.3 The effect of material thickness, colors, additives, deterioration, and possible loss of volatile components is measurable.
5.4 The results serve as a reference for comparing the relative performance of materials and can be an aid in material selection.
5.5 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it will not always be possible by or from this test method to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire-test exposure conditions described in this test method.
SCOPE
1.1 This fire-test-response test methods describe small-scale laboratory procedures for determining the comparative burning characteristics of solid plastic materials that, due to specimen thinness and nonrigidity, distort, shrink, and/or are consumed up to holding clamp when tested using Test Method D3801. A flame is applied to the base of specimens held in a vertical position and the extinguishing times are determined upon removal of the test flame.
1.2 The classification system described in Appendix X1 is intended for quality assurance and the preselection of component materials for products.
1.3 This standard measures and describes 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.
Note 1: This standard is equivalent to ISO 9773, IEC 60695-11-10, and UL 94 (Section 11).
Note 2: For rate of burning of nonrigid solid plastics in a horizontal position, formerly Test Method B of this test method, see Test Method D635.
1.4 This test method is not intended to cover plastics when used as materials for building construction or finishing.
1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.6 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. For specific hazard statements, see 6.1.1.
1.7 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.
