标准范围

给出了一种测定电容器、变压器、断路器和充油型电缆中所用透明和浅色碳氢化合物液体数量的方法。本方法适用于指数在1.33至1.7范围内且温度在20至30摄氏度的液体。在规定的精度范围内，如果液体的泡点与试验温度非常接近，以至于在发生实质性劣化之前无法获得读数，则不适用。

Gives a method for the determination of this quantity of transparent and light-coloured hydrocarbon liquids such as are used in capacitors, transformers, circuit breakers and in cables of the oil-filled type. This method is applicable to liquids having indices in the range 1,33 to 1,7 and at temperatures of 20 to 30 degrees centigrade. It is not applicable, within the accuracy stated of liquids having bubble points so close to the test temperature that a reading cannot be obtained before substantial deterioration takes place.
