1.1本标准为耐火试验响应标准。 1.2这些试验方法旨在评估软垫家具组件在特定条件下暴露于阴燃香烟后的燃烧阻力。 1.3试验适用于软垫家具组件 — 覆盖织物、内部织物、贴边线绳、铺面材料、阻隔材料和填充或填充材料，包括但不限于:天然或人造纤维的板条、泡沫或多孔填充材料、天然或人造纤维的弹性垫和松散颗粒填充材料（如聚氨酯碎片或羽毛和羽绒）。 1.4单独试验方法及其适用的材料如下: 1.4.1 覆盖织物测试 — 适用于外壳织物（见第11节和第12节）。 1.4.2 内部织物测试 — 适用于与外部织物紧密接触的内部织物（见第13节和第14节）。 1.4.3 贴边线测试 — 适用于贴边线绳（见第15节和第16节）。 1.4.4 填充/填充组件测试 — 适用于座椅或内部垂直壁（内臂和内背）的覆盖织物下使用的弹性材料（见第17节和第18节）。 1.4.5 铺面材料试验 — 适用于松散垫层下甲板中使用的弹性材料（见第19节和第20节）。 1.4.6 阻隔材料试验 — 适用于用作覆盖织物和传统聚氨酯泡沫之间屏障的材料（见第21节和第22节）。 1.5以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.6 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。 1.7 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。对于特定的危险声明， 见第7节。 ====意义和用途====== 这些测试方法旨在评估软垫家具在暴露于阴燃香烟的条件下的性能。 这是通过测试家具组件来实现的。然而，生产家具中组件之间的相互作用不一定通过组件组装测试来预测。 这些试验方法不是为了测量软垫家具在明火暴露条件下的性能，也不是为了表明家具在严重火灾暴露下是否能够抵抗火焰传播，或者以与试验标准显著不同的方式进行试验时是否能够抵抗火焰传播。 根据这些测试方法，在实体模型中测试材料组件所获得的结果不一定表明相同材料组件在其他几何配置中的性能，例如在全尺寸家具中的性能。

1.1 This is a fire-test-response standard. 1.2 These test methods are designed for the assessment of the resistance of upholstered furniture component assemblies to combustion after exposure to smoldering cigarettes under specified conditions. 1.3 The tests apply to upholstered furniture components — cover fabrics, interior fabrics, welt cords, decking materials, barrier materials, and filling or padding materials including but not limited to: battings of natural or man-made fibers, foamed or cellular filling materials, resilient pads of natural or man-made fibers, and loose particulate filling materials (such as shredded polyurethane or feathers and down). 1.4 The individual test methods and the materials to which they apply are as follows: 1.4.1 Cover Fabric Test — Applies to outer cover fabrics (see Sections 11 and 12). 1.4.2 Interior Fabric Test — Applies to interior fabrics used in intimate contact with outer fabrics (see Sections 13 and 14). 1.4.3 Welt Cord Test — Applies to welt cord (see Sections 15 and 16). 1.4.4 Filling/Padding Component Test — Applies to resilient materials used under the cover fabric in seats or in inside vertical walls (inside arm and inside backs) (see Sections 17 and 18). 1.4.5 Decking Materials Test — Applies to resilient materials used in the deck under loose cushions (see Sections 19 and 20). 1.4.6 Barrier Materials Test — Applies to materials that are intended to serve as a barrier between cover fabric and conventional polyurethane foam (see Sections 21 and 22). 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 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. 1.7 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. For specific hazard statements, see Section 7. ====== Significance And Use ====== These test methods are intended to estimate the performance of upholstered furniture under conditions of exposure to a smoldering cigarette. This is accomplished by testing furniture component assemblies. However, interactions between components in production furniture are not necessarily predicted by component assembly testing. These test methods are not intended to measure the performance of upholstered furniture under conditions of open flame exposure and do not indicate whether the furniture will resist the propagation of flame under severe fire exposure or when tested in a manner that differs substantially from the test standard. The results obtained with a material component tested in mock-up, in accordance with these test methods, do not necessarily indicate the performance of the same material component in other geometric configurations, such as in full-size furniture.
