(2,4-dioxo-1,3-benzoxazin-7-yl) ethyl carbonate

Auto flammability

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:

The melting point of the substance is very close to the cut-off for data waiving (177.4°C).
During the melting point study, the temperature was raised up to 372°C. During this study, decomposition and/or reaction of the substance occurred and a brown molten residue remained. No ignition of the substance was observed.
Additionally, the self-heating study performed at temperatures up to 140°C showed no self-ignition of the substance.
Therefore, the substance is considered to have no self-ignition temperature.

yes

Test procedure:

100 mm sample cube at 140°C

Max. temp. reached:

140

Induction time (h):

24

Result:

negative outcome (no effect observed)

Interpretation of results:

GHS criteria not met

Conclusions:

Self-heating of CH02672 was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.
From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that CH02672 is not a self-heating substance.
