Offering a range of reference fuels to support refinery analytical testing protocols for many years. The reference fuels are supplied compatible to the required ASTM standards. Our experience and commitment to safety provides you the confidence in the critical quality needed for reference fuels.

Providing the reference fuels as per the need of individual application such as high purity primary reference fuels (PRF) required to measure the motor octane number (MON) and Research Octane Number (RON) of gasoline fuels for engine knocking meeting the specifications outlined in ASTM D-2699 and D-2700  for use in a CFR test engine to determine knock ratings

• PRF Isooctane (2,2,4 trimethylpentane), which has an octane rating of 100,
• PRF n-Heptane, which has an assigned octane rating of 0 as primary reference fuels for calibration checks.
• certified blends of PRF Isooctane and PRF n-Heptane equivalent to octane ratings between 80-98 in increments of two
• Toluene Reference Fuel grade for fuel rating needs which has an octane rating of 116, for fit for use qualification testing
• certified blends of Reference Fuel grade Toluene, PRF Isooctane, and PRF n-Heptane as referenced in ASTM D-2699 and ASTM D-2700 with octane number values of 89.3, 93.4, 96.9, and 99.8 for secondary calibration against the primary reference fuels.
• blend of PRF Isooctane + 6.0 mls/Gal Tetraethyl lead (TEL) for octane testing needs above 100 octane.

All toluene standardization fuel (TSF) blends of reference fuel grade toluene, PRF isooctane, and PRF n-heptane can also be provided for all octane number accepted reference value ranges noted in the test methods instead of self-blending.
