标准范围

本文件规定了评估防水材料（如沥青或聚合物膜、涂料或油漆）中氡扩散系数的方法，以及测试期间将满足的假设和边界条件。本文件中描述的测试方法允许估计10-5 m2/s至10-12 m2/s[8][9]范围内的氡扩散系数，相关不确定性为10%至40%。

This document specifies the method intended for assessing the radon diffusion coefficient in waterproofing materials such as bitumen or polymeric membranes, coatings or paints, as well as assumptions and boundary conditions which will be met during the test.The test method described in this document allows to estimate the radon diffusion coefficient in the range of 10-5 m2/s to 10-12 m2/s^[8][9] with an associated uncertainty from 10 % to 40 %.
