Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

Administrative data

relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
Justification for type of information:
In accordance with column 2 of REACh Annex VII, the study does not need to be conducted if the substance is a solid having a melting point <=160°C.
In addition, in the ECHA endpoint specific guidance on information requirements (R.7a, v6.0, July 2017, §R.7.1.12), "solids are considered under self heating substances" and "the UN Test N.4 is preferable to generate the information for this endpoint."
The substance is described as a off-white powder (see endpoint 4.1) and according to the melting point reported in endpoint 4.2, the substance melts below 160°C. Therefore the determination of the relative self-ignition temperature was not required.
As the substance is described as a solid, self-heating properties (and UN Test N.4) was also considered in this dossier (see endpoint 4.13).
Reason / purpose for cross-reference:
