- 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
Australian Standard AS 1940 — The storage and handling of flammable and combustible liquids ; or - has a flash point of not more than 93°C
Globally Harmonised System for the classification and labelling of chemicals (GHS) .
- 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
4 Categories of Flammable Liquids
According to the Globally Harmonised System for the classification and labelling of chemicals (GHS) a flammable liquid is classified in one of four categories for this class according to the following;
| GHS category | Criteria |
|---|---|
| 1 | Flash point < 23°C and initial boiling point ≤ 35°C |
| 2 | Flash point < 23°C and initial boiling point >35°C |
| 3 | Flash point ≥ 23°C and ≤ 60°C |
| 4 | Flash point > 60°C and ≤ 93°C |
