Main Revisions
The newly added CNS 15030-29 “Classification and Labelling of Chemicals – Desensitized Explosives” defines “desensitized explosives” as “solid or liquid explosive substances or mixtures that have been desensitized to suppress explosive properties, preventing mass explosions and rapid combustion, and thus are excluded from the hazard classification ‘explosives.'”
