| Abstract: | Taken the measurement standard sample impact value level 28.6J,81.9J,127.1J and 224.5J as examples,and according to the technique and method which are recommended by JJF1059-1999(Measuring uncertainty evaluation and representation) and CSM 01 01 02 01-2006,the reason for uncertainty during measuring process has been analyzed.Furthermore,the A class and B class evaluation method have been used for evaluating the uncertainty component,composition uncertainty and extending uncertainty caused by various factors... |
