What Is Flash Point Testing?

Flash point testing determines the lowest temperature, under specified laboratory conditions, at which a liquid produces enough vapor to ignite momentarily when exposed to an ignition source.

The flash point is an important physical property used to evaluate the potential fire hazards associated with liquids.

Flash point testing is commonly used for:

• Industrial chemicals and chemical formulations

• Solvents and solvent mixtures

• Petroleum products and fuels

• Paints, coatings, and thinners

• Adhesives and resins

• Cleaning products and degreasers

• Lubricants and industrial oils

• Chemical manufacturing materials

• Waste liquids and hazardous waste characterization

• Research and product development

Flash point data helps manufacturers, safety professionals, and regulatory personnel make informed decisions regarding chemical handling, storage, labeling, transportation, and workplace safety.

ASTM Flash Point Testing Methods

Several standardized ASTM test methods are used to determine the flash point of liquids. The appropriate method depends on the sample's physical and chemical properties, anticipated flash point, and applicable regulatory requirements.

ASTM D93 – Pensky-Martens Closed Cup Flash Point Testing

ASTM D93 is a widely used method for determining the flash point of petroleum products and other liquids using a Pensky-Martens closed cup apparatus.

This method is commonly applicable to materials such as petroleum products, certain fuels, lubricating oils, and other suitable industrial liquids.

Closed cup testing is frequently used when evaluating flammability hazards and supporting product classification.

ASTM D56 – Tag Closed Cup Flash Point Testing

ASTM D56 uses a Tag closed cup apparatus to determine flash point for liquids within the method's specified applicability.

This method is commonly associated with suitable low-viscosity petroleum products and other applicable liquids.

ASTM D92 – Cleveland Open Cup Flash and Fire Point Testing

ASTM D92 determines flash point and fire point using a Cleveland open cup apparatus.

It is commonly applied to petroleum products with relatively high flash points, including certain lubricants and oils.

Flash point and fire point are different properties. Flash point identifies momentary ignition under the test conditions, while fire point indicates the temperature at which sustained burning occurs under the specified procedure.

ASTM D3278 – Small Scale Closed Cup Flash Point Testing

ASTM D3278 is a small scale closed cup flash point method used for suitable liquid products, including certain paints, coatings, solvents, and related materials.

This method may be useful when relatively small sample quantities are available.

Important: Method selection depends on the material, applicable test standard, and intended regulatory use. Contact EMSL to confirm which methods and sample types are currently supported before submitting samples.

Closed Cup vs. Open Cup Flash Point Testing

Flash point testing is generally performed using either closed cup or open cup procedures.

Closed Cup Flash Point Testing

Closed cup methods evaluate the ignition of vapor within a controlled, enclosed test apparatus.

These methods generally produce lower flash point values than open cup methods for the same material because vapors are more effectively retained.

Closed cup methods are frequently specified for regulatory classification and chemical hazard assessment.

Open Cup Flash Point Testing

Open cup testing exposes the liquid surface to the surrounding atmosphere during the procedure.

These methods are often used for certain petroleum products, lubricants, and industrial oils.

Because the testing configurations differ, results from open cup and closed cup methods should not be considered interchangeable.

Why Is Flash Point Testing Important?

1. Fire and Explosion Hazard Evaluation

Flash point testing helps identify liquids that may present fire hazards during storage, processing, transportation, and use.

2. OSHA Hazard Communication

Flash point data may support classification of flammable liquids under OSHA's Hazard Communication Standard, 29 CFR 1910.1200.

3. Department of Transportation Classification

Flash point testing may provide information relevant to the classification of certain liquids for transportation under applicable U.S. Department of Transportation hazardous materials regulations.

4. Hazardous Waste Characterization

Flash point testing may be used to evaluate the ignitability characteristic of certain liquid wastes under EPA hazardous waste regulations, including 40 CFR 261.21.

For regulatory waste determinations, the required method and other applicable criteria must be considered.

5. Safety Data Sheet Information

Flash point results can support the physical and chemical properties and hazard classification information reported in Safety Data Sheets (SDS).

6. Product Development and Quality Control

Manufacturers may use flash point analysis to evaluate product formulations, monitor consistency, and assess the impact of changes in raw materials.

Flash Point Testing for Hazardous Waste

Flash point testing is an important component of certain hazardous waste evaluations.

Under the Resource Conservation and Recovery Act (RCRA), a liquid waste may exhibit the ignitability characteristic if its flash point is below 60°C (140°F), subject to regulatory exceptions and other applicable provisions.

EPA SW-846 Method 1010 and Method 1020 address flash point testing using specified closed cup procedures.

A complete hazardous waste determination may require additional information beyond flash point results.

EMSL can assist customers in discussing analytical requirements for waste characterization projects and identifying appropriate laboratory testing options.

Flash Point Testing for Chemicals and Solvents

Industrial solvents and chemical mixtures may present fire hazards depending on their chemical composition, volatility, and flash point.
