测量不确定度在工程施工类试验检测机构中的应用

Application of Measurement Uncertainty Degree in the Testing & lnspection Institutes for Engineering Construction

按照CNASRL07—2011《测量不确定度的要求》,检测实验室应有能力对每项有数值要求的测量结果进行测量不确定度评估。介绍测量不确定度定义和计算步骤,以混凝土抗硫酸盐类侵蚀防腐剂比表面积测量结果的不确定度评定为例,介绍工程施工类试验检测机构一些常规项目和参数的测量不确定度的计算、报告的编制和评定方法。

According to CNAS RL07—2011＂Requirements of Measurement Uncertainty Degree＂ , the inspection laboratories should have the capacity to evaluate the measurement uncertainty degree for each of the measurement results that should be expressed by values. The paper introduces the definition of measurement uncertainty degree and the calculation procedures. By taking the measurement uncertainty degree evaluation of the specific surface area measurement result of the preservatives to protect concrete from sulfate corrosion , the author introduces the calculation of measurement uncertainty degree of some common items and parameters , the composition of reports and the evaluation methods suitable for testing inspection institutes for engineering construction.
