规定方法的原理是将称重的油样小份置于玻璃瓶中，在惰性（氮气）气流下以受控方式加热至500°C，持续特定时间，清除惰性气体反应过程中形成的挥发物，称量剩余的含碳残留物。该方法可用于测定蒸发和热解后留下的0,10%（m/m）至30,0%（m/m）范围内的碳残留物量。对于可能产生低于0.10%（m/m）残炭的材料，在分析前，按照ISO 3405中所述的程序制备10%（V/V）蒸馏残炭。

The principle of the method specified is placing a weighed aliquot of the oil sample in a glas vial, heating it to 500 °C under an inert (nitrogen) gas stream in a controlled manner for a specific time, sweeping away the volatiles formed during the reactions by the inert gas, weighing the carbonaceous residue remaining. The method may be used to determine amounts of carbon residues in the range of 0,10 % (m/m) to 30,0 % (m/m), left after evaporation and pyrolysis. On materials, which may yield a carbon residue below 0,10 % (m/m), a 10 % (V/V) distillation residue is prepared by the procedure described in ISO 3405 before analysis.
