Pensky-Martens Cup

The Pensky-Martens cup is a testing device used to determine the flash point of flammable liquids, which is the lowest temperature at which vapors can ignite. Essentially, it heats a sample of the liquid gradually while periodically introducing a small flame. If the vapor ignites, the temperature is recorded as the flash point. This test helps assess the flammability and safe handling temperatures of fuels, solvents, and chemicals, ensuring proper safety measures in storage, transportation, and use. The Pensky-Martens cup is a standardized and widely accepted method for such safety testing.
