| Popis: | The objective of this paper is to present a methodology for the measurement of the uncertainty in the calculation result in the shear strength test. Is intended with this work is to gather subsidies to justify the adoption of the measurement of the uncertainty in calculation procedure as a regulatory requirement and part of the report of wood characterization tests. The motivation for submitting this proposal is due to the difficulty in reaching some technical requirements specified by the rules, especially the requirement on "quality assurance testing and calibration results". The proposed methodology consolidates the procedures necessary to obtain the individual measurement uncertainty of the failure stress and the mean result of the uncertainty of failure stress. This methodology meets the requirements of a quality management system. The uncertainty values of the individual results of failure stress were negligible indicating a high-quality equipment and good calibration of them. The uncertainty of the measurement of the mean failure stress was considerable, indicating the importance of their consideration in the safety of wooden structures. |
