标准范围

与沸点在30°C至300°C范围内的液体（不包括石油产品）有关，在大气条件下蒸馏时稳定。还指定了蒸馏设备。该原理包括a）在仔细定义的条件下蒸馏测试部分，以确定与定义的冷凝液体积相对应的温度（绘制温度作为体积的函数），或b）在相同的条件下，当温度计指示每个指定的蒸馏温度时，确定冷凝液体积（绘制体积作为温度的函数）。

Relates to liquids (excluding petroleum products) having a boiling point in the range 30 °C to 300 °C and are stable during distillation in atmospheric conditions. Specifies also the distillation apparatus. The principle consists in a) distillation of a test portion under carefully defined conditions in order to determine the temperature corresponding to the condensate volumes defined (plotting temperature as a function of volume) or b) under the same conditions to determine the volume of condensate when the thermometer indicates each of the distillation temperatures specified (plotting volume as a function of temperature).
