API Spec 1581 ✓ Most Recent [ Withdrawn ]

This specification established the minimum performance and mechanical requirements and the testing and qualification procedures for aviation jet fuel filter/separators with flow rates ranging up to 9500 liters per minute (2400 gallons per minute). The specification also defines procedures to qualify filter/separators with and without multi-stages. The most significant amendment to the previous edition is the modification of the test fuel chemistries for Category C, M and M100 testing. This publication is an essential reference for all those involved in the supply of jet fuel to aircraft, and also those involved in the design, manufacture and supply of filter/separator elements.
