| Abstract: | Indoor coating materials with formaldehyde purification function have been widely used in interior decoration.In this paper,according to the test method of formaldehyde purification performance in JC/T 1074-2008,the factors influencing the test results and their interaction relationship during the test are analyzed,and the uncertainty of the measurement results is evaluated.The results show that the relative expanded uncertainty of formaldehyde concentration is 0.0226,and the relative expanded uncertainty of formaldehyde purification efficiency is 0.0592,k=2(including interval of 95%). |
