Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- JUSTIFICATION FOR DATA WAIVING
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.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
