| Abstract: | In the paper, according to GB/T17657-1999, uncertainty of formaldehyde release rate in density fireboard by acetylacetone spectrophotometry was studied. The mathematic model for measurement was established. The factors affecting the measurement result wre analyzed and evaluated in details. The combined standard uncertainty and the expand uncertainty were given. |
