ASTM E1678 煙氣毒性測試方法 – 標準名稱
ASTM E1678 Standard Test Method for Measuring Smoke Toxicity for Use in Fire Hazard Analysis
ASTM E1678 用于火災(zāi)分析的測量煙氣毒性的標準試驗方法

ASTM E1678 煙氣毒性測試方法 – 適用范圍
本火災(zāi)試驗響應(yīng)標準涵蓋了一種測定材料或產(chǎn)品在暴露于50 kW/m2的輻射熱通量15分鐘后產(chǎn)生的煙霧的致命毒性效力的方法。

本試驗方法僅限于不大于76mm×127 mm（3×5 英寸）、厚度不大于51 mm（2 英寸）的試樣。試樣旨在代表成品材料或成產(chǎn)品，包括復(fù)合材料和組合構(gòu)件。本試驗方法不適用于沒有平面或幾乎平面外表面的最終用途材料或產(chǎn)品。

使用一氧化碳、二氧化碳、氧氣（失效）和氰化氫、氯化氫和溴化氫（如果存在）的燃燒-大氣分析數(shù)據(jù)，預(yù)測與30分鐘暴露相關(guān)的致命毒性效力值。因此，計算方法僅限于那些煙霧毒性可歸因于這些毒物的材料和產(chǎn)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.
