阶段法与参考基准法联用在建材气味强度评价中的应用

The application of combination of the 1-butanol reference method and the five-points scale method in odor intensity evaluation of indoor building materials

本文利用气味强度的幂律模型,建立了五阶段法气味强度等级和参考基准法正丁醇溶液浓度的转化关系.计算出了五阶段法气味强度等级对应的正丁醇浓度,并将其应用于五阶段法评价气味等级的过程中.与传统阶段法相比,该方法具有更好的精密度和重复性,适用于评价建材产品的气味强度等级.

This study established a transforming relationship between the 1-butanol reference method and the fivepoints scale method by the power law model and the combination of the two methods was achieved.Compared with the traditional five-points scale method,the method has higher precision and repeatability and is suitable for evaluating the odor intensity level of building materials.
