LCS Laboratory Inc., measures the Flash Point of flammable liquids using the ASTM D56 procedure. The test is typically used to classify the flammability of a material for SDS authoring or GHS classification.
During the test, 55ml of a liquid sample is heated at a steady rate of 1 degree per minute in a closed copper cup. Every 30 seconds a miniature flame source is immersed into the air above the tested liquid. The lowest temperature when flammable vapor ignites is called the Flash Point of the liquid.
There are different classifications of flammable liquids based on their flash point and boiling point. A simplified classification is shown 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
Your country may have different standards. Please check your domestic regulation or the GHS standard for the proper classification of your product.
