ASTM E1678 Standard Test Method for Measuring Smoke Toxicity for Use in Fire Hazard Analysis
ASTM E1678 用于火灾分析的测量烟气毒性的标准试验方法

ASTM E1678 烟气毒性测试方法 – 适用范围
本火灾试验响应标准涵盖了一种测定材料或产品在暴露于50 kW/m2的辐射热通量15分钟后产生的烟雾的致命毒性效力的方法。

本试验方法仅限于不大于76mm×127 mm（3×5 英寸）、厚度不大于51 mm（2 英寸）的试样。试样旨在代表成品材料或成产品，包括复合材料和组合构件。本试验方法不适用于没有平面或几乎平面外表面的最终用途材料或产品。

使用一氧化碳、二氧化碳、氧气（失效）和氰化氢、氯化氢和溴化氢（如果存在）的燃烧-大气分析数据，预测与30分钟暴露相关的致命毒性效力值。因此，计算方法仅限于那些烟雾毒性可归因于这些毒物的材料和产品。

This fire-test-response standard covers a means for determining the lethal toxic potency of smoke produced from a material or product ignited while exposed to a radiant heat flux of 50 kW/m2 for 15 min.

This test method is limited to test specimens no larger than 76 by 127 mm (3 by 5 in.), with a thickness no greater than 51 mm (2 in.). Specimens are intended to be representative of finished materials or products, including composite and combination systems.

Lethal toxic potency values associated with 30-min exposures are predicted using calculations that use combustion atmosphere analytical data for carbon monoxide, carbon dioxide, oxygen (vitiation) and, if present, hydrogen cyanide, hydrogen chloride, and hydrogen bromide. The predictive equations are therefore limited to those materials and products whose smoke toxicity can be attributed to these toxicants. An animal check determines the extent to which additional toxicants contribute to the lethal toxic potency of the smoke.
