Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
Justification for type of information:

If the heat developed either by a reaction of the substance with oxygen or by exothermic decomposition is not lost rapidly enough to the surroundings, self-heating leading to self-ignition occurs. Self-ignition therefore occurs when the rate of heat-production exceeds the rate of heat loss.

Testing does not appear scientifically necessary for lead metal on the basis of other existing data for this substance: testing for flammability yieled a result of "not flammable", and no exothermic decomposition was reported during DSC analysis up to a temperature of 600 °C. Furthermore, no self-ignition properties have been observed throughout long-term industrial handling of the substance. Therefore, it can be surmised that lead metal powder and lead metal massive are not ignitable or auto-flammable; futther testing is not required and classification does not apply.
