Reference Materials

40 CFR 1090 Accuracy and Precision Reference Materials

ASTM Reference Materials are an excellent resource to help you comply with US EPA fuels regulations under 40 CFR 1090. We offer a variety of reference materials, valid as check standards per ASTM D6299, to support your laboratory’s ongoing precision and accuracy demonstration per 40 CFR 1090.1375. Implementing reference materials with reliable accepted reference values allows you to confirm compliance in real-time, reducing the risk and liability of unqualified data being reported to customers and agencies. Our available options provide ARVs in the fuel matrices being tested across a wide range of results, including those at or slightly below the applicable standards, to satisfy 40 CFR 1090.1375(c)(2):

• Vapor Pressure of Gasoline in neat and oxygenated matrices, with ARVs from 5.5 psi to 14.5 psi, including numerous batches at or below the summer season maximum RVP per gallon standards detailed in 40 CFR 1090.215(a)

• Benzene in Gasoline from 0.2 vol % to 1.1 vol %, including options at or below the benzene average standard of 0.62 vol % per 40 CFR 1090.210(a)

Octane and Cetane Reference Materials

Demonstrate control and build confidence by implementing ASTM’s combustion characteristic reference materials as part of your QC program. Our selection of combustion characteristic reference materials are ideal for ensuring and monitoring the validity of results to customers and accrediting bodies. Octane and Cetane reference materials are available in typical finished gasoline and diesel product matrices. Octane Number reference materials are available with reliable ARVs across the range from subgrade to midgrade including RON from 85 to 94 and MON 79 to 87. Cetane Number and Derived Cetane Number reference materials are available from 40 to 52.

Compositional GC Reference Materials

Validate your compositional gas chromatography instrumentation and methodology with ASTM’s composition reference materials. Shipped in packages of 8 x 5-mL ampoules, and in gasoline or naphtha matrices, our multi-ARV reference materials are a reliable way to confirm precision and accuracy of hydrocarbon group reporting and performance. Reference materials are available with ARVs for:

Distillation Reference Materials

ASTM offers a wide selection of reference materials to validate distillation measurement systems using atmospheric, vacuum, micro, simulated, and high-temperature simulated methodologies. Our distillation reference materials are in sample matrices similar to those your laboratory tests, rather than synthetic blends of multiple pure components, offering confidence for real-world testing of wide boiling ranges. Confirm instrument performance and analyst technique with our catalog of reference materials with ARVs covering the boiling range of typical petroleum and refined products, and the narrow boiling range of high purity chemicals:
