外墙保温用EPS板氧指数的测量不确定度分析

Analysis of measurement uncertainties of oxygen index for EPS on external thermal insulation

通过对建筑材料模塑聚苯乙烯泡沫塑料(EPS)保温板氧指数检测过程的研究,确定了影响检测不确定度的主要原因,并通过试验对EPS材料测量不确定度进行了评价,指出了在检测过程中需注意的问题,旨在减小检验结果的不确定度,提高检验人员在产品质量检验工作中的科学性。

Through the study of measurement uncertainties of oxygen index for moulded polystyrene foam board on external（EPS） thermal insulation,the author confirmed the main reason influencing the measurement uncertainties,evaluated the measurement uncertainties of EPS and pointed out the problems should be noticed in the testing for decreasing the measurement uncertainties of testing results and increasing the scientific nature in the course of testing for inspectors.
