ASTM D4206 Sustained Burning Testing

Pentyl Labs performs ASTM D4206 sustained burning testing to determine whether liquid mixtures are capable of sustaining combustion after ignition. This test is commonly used alongside flash point testing to support transportation classification, SDS preparation, regulatory compliance, and product safety evaluations for mixtures containing both flammable and nonflammable liquids.

ASTM D4206 Test

The ASTM D4206 Test determines whether a liquid mixture will sustain burning after ignition under controlled laboratory conditions. Pentyl Labs performs ASTM D4206 testing to help manufacturers evaluate flammability characteristics, support transportation classification, prepare Safety Data Sheets (SDSs), and meet regulatory requirements.

Unlike flash point testing, which determines the lowest temperature at which a liquid produces ignitable vapors, the ASTM D4206 Test evaluates whether a product continues to burn after the ignition source has been removed. This distinction is important because some liquid mixtures may ignite briefly but will not sustain combustion under the conditions specified by the standard.

The ASTM D4206 Test is commonly performed alongside flash point methods such as ASTM D93, ASTM D56, or ASTM D3828 to provide a more complete understanding of a product’s fire hazards and transportation classification.


What is ASTM D4206 Testing?

ASTM D4206, Standard Test Method for Sustained Burning of Liquid Mixtures Using the Small Scale Open-Cup Apparatus, evaluates whether a liquid mixture is capable of sustaining combustion after being ignited.

The test is particularly useful for products that contain both flammable and nonflammable components, including water-based formulations, solvent blends, and specialty chemical products. Results from the ASTM D4206 Test may be used during product development, hazard assessments, regulatory submissions, and shipping classifications.


Why ASTM D4206 Testing Matters

The ASTM D4206 Test provides information that flash point testing alone cannot. Some products may have a relatively low flash point but fail to sustain combustion once the ignition source is removed.

Determining sustained burning characteristics helps manufacturers better understand product hazards and can support regulatory decision-making.

Common applications include:

  • Transportation classification
  • Safety Data Sheet (SDS) preparation
  • Hazard communication
  • Product safety evaluations
  • Research and development
  • Product reformulation
  • Quality assurance testing

How ASTM D4206 Testing Works

During the ASTM D4206 Test, a measured volume of the liquid sample is placed into a standardized small-scale open-cup apparatus. The sample is ignited under controlled laboratory conditions using the procedure specified by ASTM.

Following ignition, the analyst observes whether the sample continues burning after the ignition source has been removed. The sustained burning behavior is then evaluated according to the ASTM D4206 acceptance criteria.

Pentyl Labs provides clear, regulatory-ready reports documenting the outcome of the ASTM D4206 Test.

ASTM D4206 Test FAQs

What does the ASTM D4206 Test measure?

The ASTM D4206 Test determines whether a liquid mixture continues burning after an ignition source has been removed under standardized laboratory conditions.

How is the ASTM D4206 Test different from flash point testing?

Flash point testing determines the temperature at which vapors ignite. The ASTM D4206 Test evaluates whether the product will sustain combustion after ignition.

What products can be tested?

The ASTM D4206 Test is suitable for many liquid chemical products, including solvent blends, cleaners, coatings, industrial chemicals, adhesives, and specialty formulations.

When should ASTM D4206 testing be performed?

ASTM D4206 testing is commonly performed during product development, transportation classification, regulatory submissions, SDS preparation, and flammability evaluations.
