 Class 3: Flammable Liquids
Class 3 includes flammable liquids or liquid desensitized explosives.

Flammable liquids refers to liquid, liquid mixture, solution, suspension that emit flammable atmosphere under a flash point under 60¡ÆC in the test using closed cup method. It includes liquid of which flash point is above 60 that is carried at a temperature above its flash point and material that emit flammable atmosphere under the maximum transport temperature which is transported as liquid at a high temperature.
Liquid desensitized explosives refer to stable liquid mixture which is absolved by other liquid or floated to restrain its explosiveness. It consists of UN No. 1204, 2059, 3064 and 3343. The flash point is the lowest temperature at which a liquid will generate enough vapor to form an ignitable mixture at its surface. It refers to the lowest temperature at which flash is observed when certain amount of liquid is heated. The flash point should be measured by closed up method.
Liquid means dangerous material which has a vapour pressure lower than 300kPa at 500C or which is not gaseous at 20¡ÆC and at a standard pressure of 101.3 kPa. Class 3 is classified following three packing groups according to degree of danger.

PG(Packing Group) Flash Point(¡É, c.c.) Initial Boiling Point(IBP)(¡É)
I - ¡Â 35 ¡ÆC
II £¼ 23¡ÆC £¾ 35¡ÆC
III ¡Ã 23¡ÆC ¡Â 60¡ÆC, £¾ 35¡ÆC
