(c) Substances in which, in a 10 cm sample cube, at 140 °C test temperature, spontaneous combustion or a rise in temperature to over 200 °C is observed within 24 hours shall be assigned to Class 4.2. This criterion is based on the temperature of the spontaneous combustion of charcoal, which is at 50 °C for a sample cube of 27 m3. Substances with a temperature of spontaneous combustion higher than 50 °C for a volume of 27 m3 are not to be assigned to Class 4.2.
