Flash Point Testing – ASTM D3828
Flash Point Testing – ASTM D3828 (Setaflash Small Scale)
ASTM D3828 flash point testing uses the Setaflash closed-cup method to rapidly determine the ignition temperature of small-volume liquid samples. Ideal for screening volatile cosmetics, solvents, and specialty chemicals.

ASTM D3828 Flash Point Testing | Setaflash Small Scale Method
Pentyl Labs provides ASTM D3828 flash point testing using the Setaflash Small Scale Tester. This method measures the temperature at which a liquid or semisolid material releases vapors that ignite in air. Because the test uses a small closed cup and a very small sample size, it offers fast, reliable, and efficient flash point results.
What the ASTM D3828 Method Measures
The Setaflash method heats a 2–4 mL sample in a sealed cup. At specific temperature intervals, the tester introduces a small ignition source. When a brief flash appears above the sample, that temperature is recorded as the flash point. This quick, controlled approach helps manufacturers evaluate flammability even when only limited material is available.
ASTM D3828 applies to volatile liquids, formulated products, solvents, cleaners, oils, cosmetic ingredients, and specialty chemicals. Because it requires so little material, the method works well for screening, research, and routine quality control. It is also an excellent option when speed is important.
Procedures A and B
ASTM D3828 includes two procedures:
-
Procedure A (Rapid Equilibrium): Used when a fast result is needed.
-
Procedure B (Non-Equilibrium): Used for broader material types and wider temperature ranges.
Both procedures offer accurate and repeatable results from –30 °C to 300 °C. As a result, laboratories and manufacturers use this method for regulatory labeling, shipping classification, batch release, and R&D evaluations.
Regulatory and Safety Relevance
Flash point plays an important role in hazard communication. OSHA defines it as the lowest temperature at which a liquid forms an ignitable vapor–air mixture. Because ASTM D3828 aligns with this definition and with ISO 3679, the data supports both U.S. and international documentation requirements.
For cosmetics and consumer products, FHSA classifies materials using flash point values:
-
Extremely Flammable: ≤ 20 °F (–6.7 °C)
-
Flammable: > 20 °F (–6.7 °C) and < 100 °F (37.8 °C)
-
Combustible: ≥ 100 °F (37.8 °C) and ≤ 150 °F (65.6 °C)
Therefore, D3828 results support compliance with OSHA HazCom, DOT transport rules, FHSA labeling, and FDA MoCRA requirements. Agencies such as the EPA and Health Canada often rely on this method when evaluating flammability risks for volatile materials.
