Discussion/Rationale for testing exemption:

Explosivity can be defined as the tendency of a substance to undergo violent and rapid decomposition, under appropriate conditions, to produce heat and or gas (ECHA, 2008).

According to the Method A14, Explosive Properties of Council Regulation (EC) No 440/2008 of 30 May 2008,a experimental test, “need not be performed when available thermodynamic information (e.g. heat of formation, heat of decomposition) and/or absence of certain reactive groups in the structural formula establishes beyond reasonable doubt that the substance is incapable of rapid decomposition with evolution of gases or release of heat (i.e. the material does not present any risk of explosion).”

Numerous chemical groups have been associated with explosive properties. Examples of such groups are included in Table 1.

The explosive properties of TMXDI were predicted based on its structure as per Method A14, Explosive Properties of Council Regulation (EC) No 440/2008 of 30 May 2008 and considering the guidance provided in the section R.7.1.11.3 of Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, European Chemicals Agency (ECHA), 2008.The structure of TMXDI was assessed and found not to have functionality or chemical groups associated with explosivity or that could imply explosivity.
