标准范围

规定方法的原理是将称重的试样置于坩埚中，并进行破坏性蒸馏。渣油在一段固定的剧烈加热期内发生裂化和结焦反应。在规定的加热期结束时，在干燥器中冷却并称重含有碳质残留物的试验坩埚。剩余残渣按原始试验部分的质量百分比计算。该方法可用于测定蒸发和热解后留下的0,01%（m/m）至30,0%（m/m）范围内的碳残留物量。

The principle of the method specified is placing a weighed test portion in a crucible and subjecting to destructive distillation. The residue undergoes cracking and coking reactions during a fixed period of severe heating. At the end of the specified heat period, the test crucible containing the carbonaceous residue is cooled in a desiccator and weighed. The residue remaining is calculated as a mass percentage of the original test portion. The method may be used to determine amounts of carbon residues in the range of 0,01 % (m/m) to 30,0 % (m/m), left after evaporation and pyrolysis.
