- Executive summary:
The thermal behaviour of test item was assessed using the DSC analysis, according to the OECD guideline 113. The test item was weighed into the glass crucible under an inert atmosphere (nitrogen). Two samples with about 7 mg of the test item were used in the test. The upper end of the crucible was sealed by melting with an oxyhydrogen flame. The crucible was then reweighed with an accuracy of 0.01 mg. As reference crucible, a glass crucible with aluminiumoxide was used.
The determination of the thermal stability of a substance was performed via Differential Scanning Calorimetry (DSC). The prepared crucibles (crucible with test item and reference crucible) were placed in the DSC apparatus. Both crucibles were heated up from room temperature to 500 °C with a heating rate of 3 K/min. For the determination of the thermal stability, two investigations were performed.
The test item showed a first exothermic effect from 220 °C with an average energy release of -20 J/g. An endothermic effect was detected from 240 °C. This effect led into an exothermic effect, starting from 260 °C with an average energy release of -350 J/g.
Due to the decomposition energy being below the threshold of -500 J/g, further tests for explosive properties should not be performed.
Conclusion
Due to the fact that the energy of the exothermic decomposition was below the threshold of -500 J/g, further tests for explosive properties had not to be performed.
Reference
The test item shows a first exothermic effect from 220 °C with an average energy release of -20 J/g. An endothermic effect is detected from 240 °C. This effect leads into an exothermic effect, starting from 260 °C with an average energy release of -350 J/g. Due to the fact that the energy of the exothermic decomposition was below the threshold of -500 J/g, further tests for explosive properties had not to be performed.

Justification for classification or non-classification
According to the CLP Regulation (EC) 1272/2008, 2.1.4.2. Screening procedure section, the screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release. If the screening procedure identifies the substance or mixture to be a potential explosive, the acceptance procedure (section 10.3 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria) has to be performed.
Screening procedure failed to evidence any reason for concern, on the basis that the enthalpy of decomposition of Direct Yellow 142: the test item shows a first exothermic effect from 220 °C with an average energy release of -20 J/g. An endothermic effect is detected from 240 °C. This effect leads into an exothermic effect, starting from 260 °C with an average energy release of -350 J/g.
In conclusion, the substance can be considered non explosive, according to the CLP Regulation (EC) 1272/2008.
