量块是一种高精度端面实物量具,它可以将国家的长度基准按照一定的规范逐级传递到机械产品制造环节,实现量值统一。在长度计量中作为长度标准又可以标定计量仪器、量规和量具的示值误差等。而对量块检定又是在恒温实验室中进行,在国际通用规则中对恒温实验室的测量环境空气温度,有着严格的要求,它的好坏对于日常的量块计量检定、校准有着至关重要的作用,它不仅影响所测数据 Measuring block is a kind of high-precision end physical measuring tools, it can be the length of the national benchmarks in accordance with certain standards and gradually passed to the manufacturing process of mechanical products, to achieve a unified value. In the length of the measurement as a standard length can be calibrated measuring instruments, gauges and gauges and other indication error. The block test is carried out in a constant temperature laboratory, in the international common rules for constant temperature laboratory air temperature measurement environment, there is a strict requirement, it is good or bad for the daily measurement of the measurement block, the calibration has a Important role, it not only affects the measured data
