Hazmat Class 1 Explosives are divided to 6 hazmat divisions 1.1,1.2,1.3,1.4,1.5 and 1.6 . in this article on Aviation Professional you will read about each hazmat division and identify explosives DG placards.
In this Hazmat Class 1 Explosives there are Six Divisions, see the table below :

After you get an idea
about the names of the six divisions in dangerous class 1, it is important to know
the meaning of the letters which always written beside the division number {Example
1.4S}. the letter [s] mean the compatibility group [s].
Compatibility Groups
Dangerous Goods Class 1 are assigned to one of six hazmat divisions, depending on the type of hazard they present and to one of thirteen compatibility groups which identify the kinds of explosive articles and substances that are deemed to be compatible.
Now, let us start with the first hazmat division 1.1

Note :
Only explosives in Division 1.3, compatibility groups C and G are permitted on
a cargo aircraft.
Dangerous Goods Class 1 - Division 1.4
Articles and
substances presenting no significant hazard. This division comprises articles
and substances which present only a small hazard in the event of ignition or
initiation during transport. 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 must not cause virtually instantaneous explosion of almost the
entire contents of the package.

Division
1.4 is
subdivided into various compatibility groups. The compatibility groups are
shown by a letter at the end of the code, for example S. The letter shown on
the label
may be B,C,D,E,G or S.
Note 1 : Only explosives in
Division 1.4, compatibility group S are permitted on a passenger
aircraft.
Note 2 : Only explosives in Division 1.4, compatibility groups B, C, D, E, G and S are permitted on a cargo aircraft only.
Dangerous Goods Class 1 - Division 1.5
Very insensitive
substances having a mass explosion hazard. which are so insensitive that there
is very little probability of initiation or of transition from burning to
detonation under normal conditions of transport.

of accidental initiation or propagation.
