When developing any solvent based liquid such as paint, coating, ink or perfume, it is imperative that the Flash Point is determined and declared in order to meet the stringent transport regulations laid down by governments around the world.
Used to simulate conditions in enclosed atmospheres.
Used to simulate conditions in open un-contained conditions.
Designed specifically for use with low temperature flashpoint liquids.
Flash Point is defined as “the lowest temperature of a liquid at which its vapours will form a combustible mixture with air”. It is a convenient and reliable classification of the “flammability” of many substances.
- Open Cup tests simulate an un-contained condition, for example a spillage.
- Closed Cup tests simulate an enclosed environment, for example storage in a tank or sealed container and are usually specified due to improved precision.
Most industries need to test the Flash Point of raw materials, products or waste to ensure:
Product quality - as a measure of consistency and performance comparison
Compliance testing - to test safety classification for handling, storage, transport and waste
In-service analysis - tests on in-use oils and other substances for contamination / adulteration
General safety - to evaluate hazard potential
Specifications - to check conformance
