| Abstract: | According to national standards GB/T14074-2006, the free formaldehyde content in urea-formaldehyde resin was measured by titrimetry and the various factors affecting measurement were analyzed. The uncertainty of measurement results was also evaluated. It was found that repeatability contributed to the uncertainty relatively larger in the measurement process. |
