1.1本标准为耐火试验响应标准。 1.2本试验方法提供了一种确定公共场所使用的堆垛椅燃烧行为的方法，方法是在通风良好的条件下，当一堆椅子受到指定的火焰点火源时，测量特定的火灾试验响应。 1.3本试验方法仅限于堆叠座椅。 1.4获得的测试数据描述了应用特定点火源后的燃烧行为，从点火到所有燃烧停止，经过1小时，或在测试条件下出现不可避免的闪络。 1.5本试验方法不提供堆叠座椅在本试验方法规定条件以外的火灾条件下的防火性能信息。 特别是，本试验方法不适用于香烟的阴燃点火。详见5.11。 1.6通过耗氧量法测量燃烧试样的热释放速率。详见5.11.4。 1.7其他测量是产生遮光烟雾和燃烧气体中某些有毒气体的浓度。详见5.11.5。 1.8燃烧行为通过照片或视频记录进行视觉记录。 1.9 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.10产品和材料的防火测试具有固有的危险性，在进行这些测试时，应采取适当的人员和财产保护措施。本试验方法可能涉及危险材料、操作和设备。 1.11在裁判决定中使用国际单位制；见实践E 380。括号中给出的单位仅供参考。 1.12 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This is a fire-test-response standard. 1.2 This test method provides a means of determining the burning behavior of stacking chairs used in public occupancies by measuring specific fire-test responses when a stack of chairs is subjected to a specified flaming ignition source under well ventilated conditions. 1.3 This test method is limited to stacked chairs. 1.4 Test data are obtained describing the burning behavior following application of a specific ignition source, from ignition until all burning has ceased, a period of 1 h has elapsed, or flashover under test conditions appears inevitable. 1.5 This test method does not provide information on the fire performance of stacked chairs under fire conditions other than those conditions specified in this test method. In particular, this test method does not apply to smoldering ignition by cigarettes. See 5.11 for further information. 1.6 The rate of heat release of the burning test specimen is measured by an oxygen consumption method. See 5.11.4 for further information. 1.7 Other measurements are the production of light-obscuring smoke and the concentrations of certain toxic gas species in the combustion gases. See 5.11.5 for further information. 1.8 The burning behavior is documented visually by photographic or video recordings. 1.9 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. 1.10 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. This test method may involve hazardous materials, operations, and equipment. 1.11 Use the SI system of units in referee decisions; see Practice E 380. The units given in parentheses are for information only. 1.12 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 and health practices and determine the applicability of regulatory limitations prior to use.
