This is a NEW ASTM test.  If you have a problem passing this test we have a cold flow additive located on the Store Page.

Cold Soak Filtration Analysis: The time in seconds it takes for cold soaked biodiesel to pass through two 0.8 micron filters and the amount of particulate matter expressed in mg/l collected on the filter.
For Producers/Blenders: Poor filtration can be related to choice of feedstock, as well as incomplete glycerin removal during processing. It may also indicate the B100 product was subjected to low temperatures (below pour point). It is not sufficient to warm to ambient- product must be heated to 100F to liquefy all molecules present.
For Distributors/End users: High filtration times indicate the potential for fuel filter plugging. In freezing climates, consider heat trace on storage tanks, blend and piping equipment. End users may look to install heated filter housings.
