Flashpoint and flash point testing

Flashpoint temperature

Flash point 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. Liquids are classified on the basis of flash point measurement: extremely flammable, having a flash point lower than 0oC and a boiling point less than 35oC; highly flammable, having a flash point below 21oC; flammable, having a flash point between 21oC and 55oC. A liquid with flashpoint in the range 32oC - 55oC may not require as many precautions in use as it will not form an explosive atmosphere unless it is stored at elevated temperature.

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.
