标准摘要
[中文适用范围]： 所有用于校准流量计的标准体积计量器的计量容积，均须通过校准测定，而非理论计算得出。容积式计量器具有经认可校准方法确定的精确参考容积；确定该参考容积的技术包括水排法、标准表法及称重法。本标准仅描述水排法校准技术，该方法用于准确测定容积式计量器和罐式计量器的校准容积。 [外文原描述]： All prover volumes used to calibrate meters shall be determined by calibration and not by theoretical calculation. Volumetric provers have an exact reference volume, which has been determined by a recognized method of calibration. Techniques for the determination of this reference volume include the waterdraw, master meter and gravimetric methods of calibration. This standard describes only the waterdraw method of calibration, which is used to accurately determine the calibrated volume of both displacement and tank provers.
