标准摘要
[中文适用范围]： 该方法的原理是将称重的测试部分放入坩埚中并进行干馏。 残渣在一段固定的剧烈加热时间内发生裂化和焦化反应。 在规定的加热期结束时，将含有碳质残留物的测试坩埚在干燥器中冷却并称重。 剩余的残留物计算为原始测试部分的质量百分比。 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)范围内的碳残留物的量。 [外文原描述]： 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.
