not thermal sensitive if heated under defined confinement

There was no fragmentation of tube in all tests. In any case there was a profusion of fire and smoke.

Interpretation of results:
GHS criteria not met
Conclusions:
Trimethylamine-N-oxide is not considered having explosive properties (thermal sensitivity).
Executive summary:

The explosive properties of Trimethylamine-N-oxide was tested in an EU A.14 assay (thermal sensitivity).

It is not considered having explosive properties (thermal sensitivity).

Description of key information

Method equivalent to UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating

to explosives of Class 1: EN52633 - Sensitivity to friction and EN52634 - Impact sensitivity. Not GLP but ISO/IEC 17025.

TMAO is not sensitive to friction using a friction load of 360 N and not sensitive to impact using an impact energy of 56 J.

It is not considered having explosive properties (friction/impact sensitivity).

EU Method A.14 (Explosive properties):

Thermal sensitivity - Koenen test: diameter of the orifice plate series with a 6.0 and 2.0

mm diameter orifice plate: There was no fragmentation of tube in all tests. In any case there was a profusion of fire and smoke. TMAO is not considered having explosive properties (thermal sensitivity).
