标准摘要
[中文适用范围]： 规定的设备不得用于在试验温度下表计蒸气压高于 1.4 MPa（绝对蒸气压 1.5 MPa）的材料。 描述了替代校准程序，但只有使用经过认证的比重计的校准程序才适合确定密度，以用于贸易交接或财务目的的质量计算。 [外文原描述]： The prescribed apparatus shall not be used for materials having gauge vapour pressures higher than 1,4 MPa (absolute vapour pressure 1,5 MPa) at the test temperature. Alternative calibration procedures are described, but only the one using a certified hydrometer is suitable for the determination of density to be used in calculations of qualities for custody transfer or fiscal purposes.
