Flashpoint and flash point testing

Flashpoint temperature

Flashpoint is the lowest temperature at which a liquid will form an explosive vapour under normal atmospheric conditions. It is an important measure of volatility and allows appropriate safety measures to be taken when transporting, storing or handling flammable liquids. Under CLP, liquids are classified on the basis of flash point measurement thus: Category 1 - flashpoint <23 °C and initial boiling point ≤35 °C Category 2 - flashpoint <23 °C and initial boiling point >35 °C Category 3 -  flashpoint ≥23 °C and ≤60 °C Combustible liquids with a flashpoint above 60 °C Where liquids are used or stored in the workplace at elevated temperature above their flashpoint, a fire and explosion hazard can exist similar to that presented by Category 1 or 2 flammable liquids.

Flash point test apparatus

Our UK based laboratory offers Setaflash, Pensky-Martens open cup, Pensky-Martens closed cup, Abel, Tag open & closed and Cleveland open cup flash point testing  to a variety of test standards and methods - see table below.
