期间核查是检测实验室设备是否保持良好状态的重要手段,能够保证拉力试验机在使用条件下计量特性无明显变化,满足实验室检测要求。拉力试验机在使用过程中,受到震动,冲击,环境变化,难免会影响其计量性能,从而影响到实验室检测结果的准确可靠。因此,拉力试验机除了必须定期进行检定或校准之外,还需要进行期间 Verification during the test is an important means of testing whether the laboratory equipment is in good condition, to ensure that the tensile testing machine under the conditions of use without significant changes in measurement to meet the testing requirements of the laboratory. Tensile testing machine in use, by the vibration, impact, environmental changes, will inevitably affect its measurement performance, thus affecting the accuracy and reliability of laboratory test results. Therefore, the tensile testing machine in addition to regular verification or calibration, but also the need for the period
