What is flash point?
Flash Point is the lowest temperature at which the vapor of a volatile material will ignite when an ignition source is applied. Flash Point is used to classify materials as flammable or combustible. The classification of your material will affect many requirements including labeling, storage requirements, shipping requirements and disposal.
What are the GHS classifications for flash point?
The Globally Harmonized System (GHS) of Classification and Labelling of Chemicals categorizes the flammable liquid criteria according the following flash point ranges:
|Criteria||GHS Category||Transport Class/ Packing Group|
|Flash Point < 73°F (23°C) & Initial boiling point ≤ 95°F (35°C)||1||3, I|
|Flash Point < 73°F (23°C) & Initial boiling point > 95°F (35°C)||2||3, II|
|Flash Point ≥ 73°F (23°C) & ≤ 140°F (60°C)||3||3, III|
|Flash Point > 140°F (60°C) & ≥ 200°F (93.3°C)||4||Combustible liquid, III|
Dynalene utilizes a Setaflash Series 8 closed cup flash point testing to determine the flashpoint of your material. With its small sample size requirements, rapid heating, and digital accuracy, we can test your material quickly and efficiently.
