Testing Services: Cold Flow

Method	Test	Test Details	Volume	Price ($US)
D 97	Pour Point	D 97 / Pour Point The D97 Pour Point method determines approximately the lowest temperature at which a fuel can be pumped. This test is appropriate for materials with freezing points above -52°C	50 mL	$53.00
D 2500	Cloud Point	D 2500 / Cloud Point The D2500 Cloud Point method determines the temperature at which fuel particles begin to visibly form a cloud of crystalline fuel molecules, but fuel flow is not yet completely restricted. For diesel and diesel blends, the Cloud Point gives an indication of where the Cold Filter Plug Point (D6371) may be, which is typically only a few degrees lower than the Cloud Point. At the Plug Point temperature, fuel flow is restricted. This test is suitable for biodiesel, diesel, and diesel blends.	50 mL	$38.00
D 6371	Cold Filter Plug Point	D 6371 / Cold Filter Plug Point The D6371 Cold Filter Plug Point method measures the temperature at which the fuel has produced enough crystalline structure (freezing) to restrict flow. This test is suitable for biodiesel, diesel, and diesel blends.	50 mL	$44.00
D 7501	Cold Soak Filterability	D 7501 / Cold Soak Filterability The D7501 Cold Soak Filtration method gives an approximation for the cold weather performance of a B100 product. The sample is chilled, warmed back to room temperature, and then timed for how long it takes to pass through a filter. The test is designed to check for particulates that may come out of solution at colder temperatures. The test is designed for B100, although the test can be performed for diesel and diesel blends.	350 mL	$53.00

*Our goal is to provide results for standard samples within 72 hours of receipt of sample, and RUSH service within 24 hours for most tests. Turnaround time goals reflect normal business hours of 8am-4pm Monday through Friday, excluding weekends and observed holidays. RUSH service is available at 2X normal price. For RUSH service, please contact us ahead of time to reduce any delays.

**Prices are valid December 31, 2024 - February 28, 2025
