# Regulation (EC) No 1272/2008 of the European Parliament and of the Council of 16 December 2008 on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No 1907/2006 (Text with EEA relevance), Division 2.1.2.2: Substances, mixtures and articles of this class, which are not classified as an unstable explosive, shall be assigned to one of the following six divisions depending on the type of hazard they present:

Extent: E+W+S+N.I.

(a) Division 1.1 Substances, mixtures and articles which have a mass explosion hazard (a mass explosion is one which affects almost the entire quantity present virtually instantaneously);
(b) Division 1.2 Substances, mixtures and articles which have a projection hazard but not a mass explosion hazard;
(c) Division 1.3 Substances, mixtures and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard:
(i) combustion of which gives rise to considerable radiant heat; or
(ii) which burn one after another, producing minor blast or projection effects or both;
(d) Division 1.4 Substances, mixtures and articles which present no significant hazard:
substances, mixtures and articles which present only a small hazard in the event of ignition or initiation. The effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire shall not cause virtually instantaneous explosion of almost the entire contents of the package;
(e) Division 1.5 Very insensitive substances or mixtures which have a mass explosion hazard:
substances and mixtures which have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions;
(f) Division 1.6 Extremely insensitive articles which do not have a mass explosion hazard:
articles which predominantly contain extremely insensitive substances or mixtures;
and which demonstrate a negligible probability of accidental initiation or propagation.
