Full title and description
ASTM D92-24 — Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester. Describes procedures for determining the flash point and the fire point of petroleum products using a manual or automated Cleveland open cup apparatus, including required apparatus, test conditions, and interpretation of results.
Abstract
This standard (D92-24) provides a laboratory method to measure both flash point (the lowest temperature at which vapour above a liquid ignites momentarily) and fire point (the temperature at which sustained combustion occurs) for petroleum-derived liquids using the Cleveland open cup technique. It is intended for products with relatively high flash points and is used for product characterization, quality control and regulatory classification.
General information
- Status: Current / Active (D92-24 edition in force, supersedes D92-18).
- Publication date: January 11, 2024 (ASTM designation D92-24).
- Publisher: ASTM International (American Society for Testing and Materials).
- ICS / categories: Ignitability and burning behaviour of materials and products; petroleum products (examples: ICS 13.220.40; petroleum product classifications).
- Edition / version: 2024 edition (designation D92-24), document supersedes the 2018 edition D92-18.
- Number of pages: 11 (typical published length for the D92-24 document).
Scope
The test method is applicable to petroleum products with flash points above about 79 °C (175 °F) and below approximately 400 °C (752 °F), excluding routine fuel-oil flash-point determinations (for which closed-cup methods such as ASTM D93 are generally preferred). The method covers use of both manual and automated Cleveland open cup apparatus and includes notes on precision, temperature control and safety considerations.
Key topics and requirements
- Apparatus: Cleveland open cup apparatus (manual or automated), specified cup, heating control and specified test flame characteristics.
- Test parameters: Defined temperature ramp/control, test-flame application intervals, and criteria for recording flash and fire points.
- Temperature range: Appropriate for samples with flash points generally between ~79 °C and 400 °C; units stated in SI with Fahrenheit conversions provided.
- Sample handling and volume: Specified fill level and specimen preparation instructions to ensure repeatability (typical sample volume ≈ 75 mL for the cup method).
- Precision and limitations: Precision determined for specified ranges; fire-point precision noted as less commonly specified. The method may miss small concentrations of low-flash components that closed-cup methods can detect.
- Safety and environmental notes: Warnings about thermometer types (mercury-containing instruments) and general laboratory safety; users must follow applicable safety data sheets and local regulations.
Typical use and users
Routine and forensic laboratories, refinery and petrochemical quality-control departments, product specification authors, regulatory bodies and transport/shipping compliance personnel use this method to classify flammability, monitor product quality, detect volatile contamination and support safety assessments for petroleum-derived liquids.
Related standards
Commonly referenced and complementary standards include ASTM D93 (Pensky–Martens closed-cup flash point test), ASTM D1310 (Tag open-cup), Test Method D4206 (sustained burning open-cup), and international equivalents/guides (for example ISO methods for flash point). The D92 method is maintained under ASTM Committee D02 (Petroleum Products, Liquid Fuels, and Lubricants).

FAQ
Q: What is this standard?
A: ASTM D92-24 is the 2024 edition of the Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester — a laboratory procedure to determine flash and fire points of petroleum liquids using the Cleveland open cup.
Q: What does it cover?
A: It covers apparatus, specimen preparation, test procedure, temperature control and interpretation of flash and fire points for applicable petroleum products (general applicability ~79 °C to 400 °C), plus notes on precision, limitations and safety.
Q: Who typically uses it?
A: Petrochemical and refinery laboratories, third‑party testing labs, product quality teams, standards writers and regulators use D92 for product classification, QC and safety-related testing.
Q: Is it current or superseded?
A: The D92-24 edition is current and supersedes the prior D92-18 edition (document active as the 2024 ASTM release). Users should always confirm currency with ASTM or their standards provider before use.
