Description of key information

Not explosive with regard to heat or shock (DSD criteria).
Testing according to CLP criteria waived, based on chemical structure.

Key value for chemical safety assessment

Additional information

A key study was provided according to EC A14 method with regard to influence of a flame and shock.

Despite the substance HMD is a mass crystallised solid at ambient temperature, it is intended to be handled and used always in liquid form at around 80°C. Therefore, testing with regard to friction was judged unnecessary.

No chemical groups associated with explosive properties present in the molecule, therefore the acceptance procedure for Class 1 explosives shall not apply.

Justification for classification or non-classification

Based on experimental testing, hexamethylene diamine is not classified as explosive with regard to heat or shock, according to Directive 67/548/EEC criteria.

Based on chemical structure, hexamethylene diamine is not considered as a potential explosive, according to Regulation N°1272/2008 criteria.
