LCS Laboratory Inc. specializes in Flash Point testing for flammable liquids, following the ASTM D56 procedure to determine the temperature at which flammable vapours ignite. This test is essential for SDS authoring and GHS classification of hazardous materials.
How Flash Point Testing Works
In our lab, 55 mL of the sample liquid is gradually heated in a closed metal cup at a rate of 1°C per minute. Every 30 seconds, a miniature flame is introduced above the liquid. The Flash Point is recorded as the lowest temperature at which vapours ignite.
Flammability Classifications
Flash Point testing supports the classification of flammable liquids, as outlined below:
- Extremely flammable: Flash point < 23°C and initial boiling point ≤ 35°C
- Highly flammable: Flash point < 23°C and initial boiling point > 35°C
- Flammable liquid: Flash point ≥ 23°C and ≤ 60°C
- Combustible liquid: Flash point ≥ 60°C and ≤ 93°C
Note: Regulations vary by country; consult local regulations or GHS standards for precise classification requirements.
