SUBPART 8Self-reactive Substances and Mixtures

Definitions

Marginal note:Definitions

 The following definitions apply in this Subpart.

as packaged

tel qu’il est emballé

as packaged means packaged in the form and condition described in test series B, D, G and H of Part II of the Manual of Tests and Criteria. (tel qu’il est emballé)

explosive properties

propriétés explosives

explosive properties means the properties of a self-reactive substance or mixture that, in laboratory testing according to test series A, C or E of Part II of the Manual of Tests and Criteria, make the substance or mixture liable to detonate, deflagrate rapidly or show a violent effect when heated under confinement. (propriétés explosives)

self-reactive

autoréactif

self-reactive means, in relation to a thermally unstable liquid or solid product, mixture or substance, liable to undergo a strongly exothermic decomposition, having a heat of decomposition equal to or greater than 300 J/g, even without participation of oxygen. (autoréactif)
