Key result
Parameter:
other: decomposition energy
Remarks on result:
other: No sufficient heat release detected to indicate explosive properties up to 500 °C
Remarks:
Energy (J/g): -190

No sufficient heat release has been detected to indicate explosive properties up to 500 °C. Testing according to UN-MTC*) procedure is not necessary.

Interpretation of results:
GHS criteria not met
Conclusions:
No sufficient heat release has been detected to indicate explosive properties up to 500 °C. Therfore Solvent violet 36 can be classified as not explosive. Testing according to UN-MTC*) procedure is not necessary.
Executive summary:

A screening DTA (based on DIN 51007) was made in order to rule out a decomposition of Solvent violet 36. A sample of the test item in a sealed glass ampoule was heated up in a DTA oven with a linear rate of 3 K/min up to 500 °C. A sample of aluminum oxide was heated in the same oven as comparison. The temperature difference of both sample were recorded electronically. From these differences the heat flow of transformation of the test item was calculated electronically. The result was plotted as time/heat-flow diagram. Integration gives the heat release of the transformation. The test was made twice. No sufficient heat release has been detected to indicate explosive properties up to 500 °C. Therfore Solvent violet 36 can be classified as not explosive. Testing according to UN-MTC*) procedure is not necessary.

Description of key information
