BS ISO 13344:2015提供了一种估算火灾污水致命毒性的方法 由暴露在物理火灾模型的特定燃烧条件下的材料产生。 致死毒性效力值与所选火灾模型、暴露场景特别相关 并对材料进行了评估。通过计算预测与大鼠30分钟暴露相关的致死毒性效力值 利用燃烧大气中一氧化碳（CO）、二氧化碳（CO2）的分析数据， 氧气（O2）（腐蚀）和氰化氢（HCN）、氯化氢（HCl）、氢气（如果存在） 溴化物（HBr）、氟化氢（HF）、二氧化硫（SO2）、二氧化氮（NO2）、丙烯醛和 甲醛。试样的化学成分可能表明存在额外燃烧 要量化和包含的产品。如果火灾流出物的毒性不能归因于 分析毒物（附录A），这表明必须考虑其他毒物或因素。本国际标准适用于火灾污水致命毒性的评估 在实验室条件下生产的材料或组件 不应单独用于描述或评估材料、产品的毒性危害或风险 或实际火灾条件下的组件。然而，该试验的结果可作为试验的要素 火灾危险评估，考虑了与火灾危险评估相关的所有因素 特定最终用途的火灾危险；参见ISO 19706。消防安全工程计算的预期用途是预测人的生命安全，并且 最常见的是时间间隔略短于30分钟。这是跨物种的推断 暴露间隔不在本国际标准的范围内。本国际标准并非旨在解决与其相关的所有安全问题 使用本国际标准的使用者有责任制定适当的安全和环境标准 健康实践。在购买ISO时，所有ISO ACT702和ISO 135702的最新修订版均包含在ISO 2001:702的采购中。

BS ISO 13344:2015 provides a means for estimating the lethal toxic potency of the fire effluent produced from a material while exposed to the specific combustion conditions of a physical fire model. The lethal toxic potency values are specifically related to the fire model selected, the exposure scenario and the material evaluated.Lethal toxic potency values associated with 30-min exposures of rats are predicted using calculations which employ combustion atmosphere analytical data for carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) (vitiation) and, if present, hydrogen cyanide (HCN), hydrogen chloride (HCl), hydrogen bromide (HBr), hydrogen fluoride (HF), sulfur dioxide (SO2), nitrogen dioxide (NO2), acrolein and formaldehyde. The chemical composition of the test specimen may suggest additional combustion products to be quantified and included. If the fire effluent toxic potency cannot be attributed to the toxicants analysed (Annex A), this is an indication that other toxicants or factors must be considered.This International Standard is applicable to the estimation of the lethal toxic potency of fire effluent atmospheres produced from materials, products or assemblies under controlled laboratory conditions and should not be used in isolation to describe or appraise the toxic hazard or risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire hazard assessment that takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use; see ISO 19706.The intended use of fire safety-engineering calculations is for life-safety prediction for people and is most frequently for time intervals somewhat shorter than 30 min. This extrapolation across species and exposure intervals is outside the scope of this International Standard.This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices.Cross References:ISO 13571ISO 13943:2008ISO 19701ISO 19702ISO 19706Toxic Substances Control ActAll current amendments available at time of purchase are included with the purchase of this document.
