What is the difference between Cleveland open cup flash point and closed cup flash point test?

Flash point is measured using either an open cup or closed cup flash point tester. Open cup tests are required in some specifications and regulations, and are intended to mimic conditions in open spaces, whereas closed cup tests are closer to most situations, where space is restricted.

What is the limitation of Abels closed cup apparatus?

1. It lacks precision. 2. It gives a higher flash point than a closed cup as it allows free loss of vapours to the atmosphere.
