Additional information

Justification for classification or non-classification

Explosive screening test, USEPA OPPTS 830.6316: 


the test item had one endothermic peak and two exothermic peaks. The area (heating energy) of the endothermic heat peak was 107.8 J/g (at the temperature of 138.9℃). One area (heating energy) of the exothermic peak was 102.7 J/g (at the temperature of 309.4℃),and the other area (heating energy) of the exothermic peak was 49.54 J/g (at the temperature of 333.5℃).


In accordance with Regulation (EC) No. 1272/2008 section 2.1.4.3 (c), a substance or mixture shall not be classified as explosive if:when the organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 ℃. Therefore, the substance shall not be classified as explosive.
