我省某建筑工程质检站反映:该站使用300kN水泥压力试验机检测水泥抗压强度,将其检测数据与兄弟单位比对,同样一组试块的抗压强度明显偏高,便怀疑其试验机示值超差。于是笔者便使用数字式标准测力仪对该台试验机及用于比对工作的另外一台试验机进行了检定,结果两台设备均合格且 A construction project in our province quality inspection station reflects: The station uses 300kN cement pressure testing machine to test the compressive strength of cement, the test data compared with the fraternal units, the same block a significant high compressive strength, it is suspected Tester showed tolerance. So I use the digital standard dynamometer on the test machine and for the comparison of the work of another test machine was tested, the results of both devices are qualified and
