Standard Test Method for Flash Point by Pensky-Martens Closed Cup Tester

The Standard Test Method for Flash Point by Pensky-Martens Closed Cup Tester measures the lowest temperature at which a liquid produces enough vapor to ignite momentarily when exposed to a flame. In this test, a small sample of the liquid is gradually heated in a sealed container while a test flame is periodically brought near the surface. The temperature at which the vapor ignites is recorded as the flash point. This measurement helps assess the flammability and safe handling temperature of combustible liquids, ensuring proper safety measures in storage and transportation.
