EI revises handbook on aviation fuel cleanliness

Released on 19/11/2014

The Energy Institute (EI) today has published EI 1550 Handbook on equipment used for the maintenance and delivery of clean aviation fuel (2nd edition), updating one of the key information resources for the aviation fuel supply industry.

The first edition, published in 2007, became one of the most widely distributed EI publications and was cited by the International Civil Aviation Organization in its Doc 9977 Manual on civil aviation jet fuel supply.

The second edition continues to provide an overview of the technical requirements from the series of EI aviation fuel filter specifications, which is specifically intended for filter users (rather than equipment manufacturers), and it goes on to define good practice in the implementation and operation of filtration systems.

The updated EI 1550 handbook has been produced to take into account key developments in aviation fuel filtration in recent years. A significant development to the publication is the provision of new information on the measurement and monitoring of the differential pressure across a filter vessel. This is the primary means by which a filtration system alerts an operator to a fuel contamination event (by particulate matter/free water), or the failure of a filtration system. This critical activity has been explained in some detail, to provide an educational resource for use by operating companies.

In addition, five completely new chapters have been added which cover:

  • differential pressure: its measurement, monitoring and correction
  • de-rating filter monitor vessels with blank/dummy elements and filter/water separators with blinds/caps
  • filtration system installations (fixed facilities)
  • management of change
  • manufacturer’s model codes for filter elements

The information provided in EI 1550 has been drawn from, and reviewed by, filter manufacturers, global operators and other leading industry specialists, and is closely aligned with the requirements of operational standards such as ATA 103 (published by Airlines for America) and Joint Inspection Group (JIG) Standards.

This second edition will assist anyone responsible for designing, purchasing, operating, maintaining or inspecting aviation fuel filtration systems, whether they are positioned at refineries, in distribution systems or at airports.
