ISO 21687:2007规定了测定生坯和煅烧石油焦及类似固体材料(如电极)密度的方法。ISO 21687:2007也适用于高温沸腾范围内的碳氢化合物和其他固体材料。
这种方法不适用于石墨化材料。
ISO 21687:2007 specifies a method for the determination of the density of green and calcined petroleum coke and similar solid materials (e.g. electrodes). ISO 21687:2007 is also suitable for hydrocarbons with a high-temperature boiling range and for other solid materials.
This method is not suitable for graphitized material.
