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

Description of key information

In accordance with the column 2 of REACH Annex VII, the study does not need to be conducted for solids, if the substance has a melting point ≤ 160°C.

Moreover, the substance decomposes under test conditions due to Self-Accelerating Decomposition and not due to an oxidative self-heating. The relevant parameter for thermal stability is the Self-Accelerating Decomposition Temperature (SADT). Self-Accelerating Decomposition Temperature (SADT) of [1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is 80°C (reference SADT: CLP regulations 2.15.2.3 and UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 5th revised edition, sub.sections 28.1, 28.2, 28.3 and Table 28.3).
