Administrative data

Endpoint:
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:
JUSTIFICATION FOR DATA WAIVING
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 dark brown sticky high viscous resin in clumps in different sizes to solid (see endpoint 4.1) and is is flowable at approximately 80°C(see endpoint 4.4, Laus,2018). Then, the substance is considered as totally molten below 160°C and the determination of the relative self-ignition temperature is not required.
Considering 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).
