当检定平行平尺直线度和平行度时,检定人员一般并不对所得数据进行验证,也不判断检定结果可靠与否。实践证明多数平行平尺两工作面检定结果均呈凸状,而用千分尺检定平行度时,平尺中部厚度并不大于甚至明显小于两端厚度,致使平行度误差与直线度误差两者实际形状不符,尤其是轻工 When testing the parallel flat-foot straightness and parallelism, the verification staff generally do not verify the data obtained, nor to determine the reliability of the test results. Practice has proved that the majority of parallel flat-foot two face test results were convex, and with a micrometer test parallelism, the central flat-foot thickness is not greater than or even significantly less than both ends of the thickness, resulting in parallelism error and straightness error of the actual shape of both Does not match, especially light industry
