These are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (e.g. paints, varnishes, lacquers, etc., but not including substances which, on account of their other dangerous characteristics, have been included in other classes) which give off a flammable vapour at or below 61 deg C (141 deg F) closed cup test (corresponding to 65.6 deg C (150 deg F) open cup test), normally referred to as the flashpoint.
Class 3 also includes:
Liquids offered for transport at temperatures at or above their flashpoint; and
substances transported or offered for transport at elevated temperatures in a liquid state which give off a flammable vapour at temperatures equal to or below the maximum transport temperature.
However, the provisions of the IMDG Code need not apply to such liquids with a flashpoint of more than 35 deg C (95 deg F) which do not sustain combustion. Liquids are considered to be unable to sustain combustion for the purposes of the Code if:
they have passed the suitable combustibility test (see the Sustained Combustibility Test prescribed in Part III, chapter 32.5.2 of the United Nations Manual of Test and Criteria); or
their fire point according to ISO 2592:1973 is greater than 100 deg C; or
they are water-miscible solutions with a water content of more than 90%, by mass
“Inflammable” has the same meaning as “flammable”, Poisonous” has the same meaning as “toxic”. Where the flashpoint is indicated for a volatile liquid it may be followed by the symbol “c.c.”, representing determination by a closed cup test, or by the symbol “o.c.”, representing an open cup test. Liquid desensitized explosives are explosive substances which are dissolved or suspended in water or other liquid substances, to form a homogeneous liquid mixture to suppress their explosives properties. Entries in the Dangerous Goods List for liquid desensitized explosives are: UN 1204, UN 2059, UN 3064 and UN 3343.
