| Abstract: |
| The simply supported beam notched impact strength of ABS was determined according to GB/T 1043.1-2008. The source of measurement uncertainty was analyzed. The evaluation method of measurement uncertainty was determined. The uncertainty introduced from systematic errors of impact tester and vernier caliper was evaluated by type B evaluation of uncertainty; the uncertainty introduced from random errors of determination was evaluated by type A evaluation of uncertainty. Combined uncertainty was calculated with relative uncertainty, and expanded uncertainty was calculated too. The result of expanded uncertainty accorded with the measurement precision described in annex B of GB/T1043.1-2008. |
