Class 3 Flammable Liquids
Comprises liquids or mixtures of liquids or
liquids containing solids in solution or in suspension ( like my previous
examples ), but not including substances otherwise classified on account of
their dangerous characteristics) which give off a flammable vapour at
temperatures of not more than 60°C closed-cup test or not more than 65.6°C
open-cup test normally referred to as the flash point.
This hazard class has no subdivisions.

Packing Groups
How to Assign a Packing Group for any Flammable liquid ?
Some dangerous goods (Class 1, Class 2, Division 6.2 and Class 7) are not assigned into 3 packing groups I, II and III based on the degree of danger they present.
The remaining dangerous goods classes are assigned into 3 packing groups (also known
as UN Packing Group) in accordance with the degree of danger they present.
The packaging requirements for dangerous goods assigned to UN packing group I are much higher than the dangerous goods assigned to packing group II and III.
In this article, we will show you how to assign packing groups for dangerous goods class 3 Flammable liquids.
This table explain the scope of initial boiling points and flash points for each packing group :
Packing Group I: High danger
Assigned to flammable liquids with an initial boiling point less-than-or-equal-to 35°C
Examples: carbon disulphide, isopropylamine.
Packing Group II: Medium danger
Assigned to flammable liquids with a flash point less-than-23°C and an initial boiling point of greater than 35°C.
Examples: petrol, isopropyl alcohol, acetone.
Packing Group III: Low danger
Assigned to flammable liquids with a flash point greater-than-or-equal-to 23°C but less-than-or-equal-to 60°C and an initial boiling point of greater than 35°C.
Examples: kerosene, tea tree oil.
