| Abstract: | According to the technical specification for the evaluation and expression of measurement uncertainty, measurement uncertainty evaluation on specific surface area determined with gas adsorption method and pore size distribution of porous material were conducted. Combined standard uncertainty and expanded uncertainty were obtained by evaluating each main uncertainty quantity, and the main effect factors on the uncertainty of measurement results had been found. |
