API Spec 1581 [ Withdrawn ]

This standard specifies 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 lpm (2500 gpm). This specification defines procedures to qualify filter/separators with and without multi-stages. It does not qualify the actual multi-stage device(s). The inclusion of additive packages in this publication is for testing purposes only and does not constitute acceptance or rejection of these additives in jet fuels by API/IP. The performance specifications in this publication are for testing purposes only and do not necessarily constitute recommendations by API/IP for specifications in any application of the filter/separators.
