1.1 这是火灾测试响应标准。 1.2 本试验方法的目的是通过测量家具样本在通风良好的条件下经受指定的燃烧点火源时的特定火灾试验响应，确定公共场所使用的软垫家具的燃烧行为。 1.3 从特定点火源获得描述燃烧行为的数据，直到所有燃烧停止，经过1小时，或闪络不可避免。 1.4 本试验方法不提供在规定条件以外的火灾条件下软垫家具防火性能的信息。 特别是，本试验方法不适用于香烟的阴燃点火。看见 X1.6 了解更多信息。 1.5 燃烧试样的热释放速率通过耗氧量法测量。看见 X1.6.4 了解更多信息。 1.6 测量遮光烟雾的产生，并确定燃烧气体中某些有毒气体的浓度。看见 X1.6.5 了解更多信息。 1.7 尽可能通过照片或视频记录直观记录燃烧行为。 1.8 裁判裁决中使用的单位制是国际单位制，请参阅 IEEE/ASTM 国际单位制- 10 只有括号中给出的单位仅供参考。 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 防火测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.11 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、健康和环境实践，并确定监管限制的适用性。 1.12 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法提供了一种测量因燃烧软垫家具样本而产生的各种火灾试验响应特性的方法。在使用丙烷气体燃烧器点火后，允许软垫家具样品在通风良好的条件下自由燃烧。 测得的最重要的火灾试验响应特性是热释放速率，它量化了产生的火灾强度。 5.2 热释放速率是根据耗氧量原理测量的。本文讨论了耗氧量热法的假设和局限性 附件A4 ，尤其是 A4.1.2 . 5.3 测量了其他火灾试验响应特性，即烟雾遮蔽和燃烧气体释放，因为它们在作出消防安全决策时也很重要。 5.4 烟雾中最重要的气体成分是碳氧化物，存在于所有火灾中。它们是大气毒性和燃烧完整性的指标。 碳氧化物浓度的测量有两个用途:作为火灾危险评估计算的一部分，并提高热释放测量的准确性。特定于某些材料的其他有毒燃烧气体对确定燃烧完整性不太重要，是可选措施，但火灾危险评估通常需要对其进行测量。 5.5 选择的点火类型（火源）在公共场所的意外和故意火灾中都很常见。因此，本试验方法适用于公共场所的软垫家具。此类设施包括但不限于监狱、监狱、疗养院、医疗保健设施、公共礼堂、酒店和汽车旅馆。 5.6 已经证明，如果气体燃烧器以13升/分钟的流速使用80秒（相当于19.3千瓦），如《加利福尼亚技术公报》（CA TB）133所示，则其近似于座垫上五张皱巴巴的报纸的点火倾向。 5.7 本试验方法规定了丙烷气体的特定流速和气体流动周期。如果点火条件发生变化，则结果将偏离为本测试选择的模型。 5.8 本试验方法不适用于香烟点燃软垫家具。 5.9 本试验方法中使用以下三种试验配置之一: 5.9.1 A- 具有以下尺寸的试验室:3.66 x 2.44 x 2.44 m高。 5.9.2 B- 具有以下尺寸的试验室:3.66 x 3.05 x 2.44 m高。 5.9.3 C- 开放式热量计（或家具热量计）。 5.10 中列出的三种测试配置中的测量值 5.9 对于热释放率低于600 kW的管道中的热释放，已显示出类似的结果（参见 X1.4 ) ( 1. ) . 9 5.11 本试验方法中可选的室内温度、气体浓度和烟雾遮蔽测量取决于房间大小。 5.12 本测试方法旨在详细说明能够按照CA TB 133的要求运行测试的设备的制造和操作方法。 然而，该测试方法比技术公告更通用。

1.1 This is a fire-test-response standard. 1.2 The purpose of this test method is to determine the burning behavior of upholstered furniture used in public occupancies by measuring specific fire-test responses when the specimen of furniture is subjected to a specified flaming ignition source under well-ventilated conditions. 1.3 Data are obtained describing the burning behavior from a specific ignition source until all burning has ceased, a period of 1 h has elapsed, or flashover appears inevitable. 1.4 This test method does not provide information on the fire performance of upholstered furniture in fire conditions other than those conditions specified. In particular, this test method does not apply to smoldering ignition by cigarettes. See X1.6 for further information. 1.5 The rate of heat release of the burning specimen is measured by an oxygen consumption method. See X1.6.4 for further information. 1.6 The production of light obscuring smoke is measured and the concentrations of certain toxic gas species in the combustion gases are determined. See X1.6.5 for further information. 1.7 The burning behavior is visually documented by photographic or video recordings, whenever possible. 1.8 The system of units to be used in referee decisions is the SI system of units, see IEEE/ASTM SI-10 only. The units given in parentheses are for information only. 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 is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.11 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. 1.12 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 provides a means to measure a variety of fire-test-response characteristics resulting from burning a specimen of upholstered furniture. The upholstered furniture specimen is allowed to burn freely under well-ventilated conditions after ignition using a propane gas burner. The most important fire-test-response characteristic measured is the rate of heat release, which quantifies the intensity of the fire generated. 5.2 The rate of heat release is measured by the principle of oxygen consumption. The assumptions and limitations of oxygen depletion calorimetry are discussed in Annex A4 , and in particular in A4.1.2 . 5.3 Other fire-test-response characteristics are measured, namely smoke obscuration and combustion gas release, as they are also important in making decisions on fire safety. 5.4 The most important gaseous components of smoke are the carbon oxides, present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: as part of fire hazard assessment calculations and to improve the accuracy of heat release measurements. Other toxic combustion gases, which are specific to certain materials, are less crucial for determining combustion completeness and are optional measures, but fire hazard assessment often requires their measurement. 5.5 The type of ignition chosen (a flaming source) is common in both accidental and intentional fires in public occupancies. This test method is thus applicable to upholstered furniture in public occupancies. Such facilities include, but are not limited to, jails, prisons, nursing care homes, health care facilities, public auditoriums, hotels, and motels. 5.6 It has been shown that if the gas burner is used at a flow rate of 13 L/min for 80 s (equivalent to 19.3 kW), as is the case in California Technical Bulletin (CA TB) 133, it approximates the ignition propensity of five crumpled sheets of newspaper located on the seating cushion. 5.7 This test method specifies both a particular flow rate of propane gas and a period of gas flow. If the ignition conditions are changed, the results would then deviate from the model selected for this test. 5.8 This test method is not applicable to ignition of upholstered furniture by cigarettes. 5.9 One of the following three test configurations is to be used in this test method: 5.9.1 A— A test room with the following dimensions: 3.66 by 2.44 by 2.44 m high. 5.9.2 B— A test room with the following dimensions: 3.66 by 3.05 by 2.44 m high. 5.9.3 C— An open calorimeter (or furniture calorimeter). 5.10 Measurements in the three test configurations listed in 5.9 have been shown to give similar results for heat release in the duct, for heat release rates lower than 600 kW (see X1.4 ) ( 1 ) . 9 5.11 Measurements of temperatures, gas concentrations, and smoke obscuration in the room, which are optional in this test method, are dependent on room size. 5.12 This test method has been designed to give details for the means to build and operate equipment capable of running tests as required by CA TB 133. This test method is, however, more general than that technical bulletin.
