This advanced system delivers a safe, dependable, and fully automated testing solution for laboratories and industrial quality control applications. It supports accurate classification of flammable and combustible liquids while ensuring efficient compliance testing and consistent performance across routine analysis workflows.

What Is Flash Point Testing?

Flash point testing determines the lowest temperature at which a material releases sufficient vapor to ignite in air when exposed to an ignition source. It is a key safety and performance indicator used to evaluate the flammability characteristics and classification of fuels, oils, solvents, and other volatile substances.

Flash point results are widely used for:

• Classifying and labeling hazardous materials

• Meeting transport, handling, and safety regulations

• Quality control in petroleum refining, lubricants, chemicals, and coatings industries

Pensky-Martens Closed Cup Method – ASTM D93

The ASTM D93 standard defines the Pensky-Martens Closed Cup method for determining flash point in liquids with viscosity above 5.5 mm²/s (cSt) at 40°C, as well as materials containing suspended solids or those prone to forming surface films.

This method is commonly applied to:

• Fuel oils (diesel and biodiesel blends)

• Lubricating oils

• Solvents

• Paints and varnishes

• Other viscous or semi-solid liquids

ASTM D93 Test Procedures

The standard includes three testing procedures:

• Procedure A: Suitable for fuels and liquids with flash points ranging from 40°C to 360°C

• Procedure B: Designed for samples prone to surface film formation or skin development

• Procedure C: Used for biodiesel blends and defined fuel mixtures
