ASTM D56

Flash Point by Tag Closed Cup Tester

Applicability: ASTM D56 is a standard test method used to determine the flash point of liquids, primarily those with low viscosity and flash points below 93°C (200°F). It’s widely applied in industries where safety and compliance are critical, such as in the testing of fuels, solvents, chemicals, and paints. The test method helps classify materials as flammable or combustible, and informs safety regulations for storage, transportation, and handling.

Purpose: The primary purpose is to measure and describe the properties of materials in response to heat and flame, particularly for liquids with low viscosity and flash points below 93°C (200°F). This test is crucial for classifying liquids as flammable or combustible, and for assessing fire risk.
