General Information:

ISO 17034 Freezing Point of Aviation Fuels Certified Reference Materials (CRM) intended to be used for verification of measuring equipment, method validation, method verification, or other quality control processes used to determine freezing point, applicable for the test method ASTM D2386, or test methods IP 16, ISO 3013, or other applicable methods.
The freezing of an aviation fuel is an index of the lowest temperature of its utility for certain applications. Solid hydrocarbon crystals can restrict the flow of fuel in the fuel system of the aircraft. The temperature of the fuel in the aircraft tank normally decreases during flight depending on aircraft speed, altitude, and flight duration. The freezing point of the fuel must always be lower than the minimum operational fuel temperature. Petroleum blending operations require precise freezing point measurements. Typical freezing point of aviation fuels is in the range −40°C to −65°C.
ARO's Freezing Point of Aviation Fuels Certified Reference Materials have been characterized in accordance with ASTM D2386 or equivalent test method. Manufacturing, testing and certification has been performed in accordance with ARO's accreditation to ISO 17034, UKAS CAB No. 27393.
