标准范围

规定的仪器不得用于在试验温度下表压蒸汽压力高于1.4 MPa(绝对蒸汽压力1.5 MPa)的材料。本文描述了替代校准程序,但只有使用经认证的比重计的校准程序适用于测定密度,以用于监管转移或财政目的的质量计算。

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.
