Vapour pressure

Administrative data

Endpoint:

vapour pressure

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the melting point is above 300°C

Applicant's summary and conclusion

Conclusions:

According to the Annex VII of the REACH Regulation (EC 1907/2006), the study on vapour pressure does not need to be conducted if the melting point is above 300 °C.
In a DSC analysis on target substance, no melting point was reported up to 600 °C, prior to the exothermic decomposition of the test item, starting at around 205 °C.
