标准范围

真空脱气后，在25℃下用比重瓶法测量密度。煅烧焦炭可以用不同类型的油处理，以避免在装载和运输过程中形成灰尘。本方法不适用于样品中可能存在的微量油的测定。

The density is meassured at 25 degrees centigrade by a pyknometric method after degassing under vacuum. Calcined coke may be treated with different types of oil in order to avoid the formation of dust during loading and transportation. The present method does not provide for this elemination of traces of oil which may be present in the sample.
