The evaluation of uncertainty for formaldehyde content measurement in school uniforms
This paper analyzes the uncertainty of formaldehyde content in school uniforms combined with the mathematical model and evaluates each uncertainty component and analyzes the main sources of uncertainty based on GB/T 2912.1-2009 Textiles-Determination of formaldehyde-Part1:Free and hydrolyzed formaldehyde(water extraction method).As can be seen from the eval-uation,the most influential factor in formaldehyde content determination in school uniforms is the uncertainty introduced by the formaldehyde concentration of the standard solution.
