  • Edition: 2nd

Overview:

EI 1533 provides essential quality assurance requirements and recommendations for the manufacture of synthetic (jet fuel) blending components (SBC), (in accordance with ASTM D7566), their export and import, blending with conventional jet fuel/jet fuel components to produce semi-synthetic jet fuel (also known as Sustainable Aviation Fuel), co-processing to produce semi-synthetic jet fuel, and the export/import of semi-synthetic jet fuel from its point of origin through to delivery to airports.

EI 1533 is a supplement to, and intended to be read in conjunction with, EI/JIG Standard 1530.

Some of the main changes in this second edition are:

  • Inclusion of references to, and information regarding, ASTM D7566 Annex A8 alcohol to jet synthetic kerosene with aromatics (ATJ-SKA).
  • Repositioning of information on co-processing to a stand-alone chapter, to reflect recent and potential future changes to percentage limitations in governing jet fuel specifications.
  • Inclusion of specific references to jet fuel specification GB 6537.
  • Inclusion of requirements for SBC tank settling time prior to release.
  • Inclusion of requirements for change of grade cleaning procedures for road tankers/rail tank cars for the transportation of SBCs.
  • Inclusion of requirements for testing of static stock.
  • The removal of reference to Parts 1 and 2 of ASTM D7566 Table 1, as the two parts have been merged with Table 1 in the latest version of ASTM D7566.
  • Inclusion of soak testing requirements for facilities handling SBCs.

This second edition has been prepared by a broad collaboration of quality assurance specialists who have defined the mandatory provisions considered essential for the maintenance of SBC and semi-synthetic jet fuel quality from its point of manufacture through distribution systems to airports. EI 1533 is intended to assist in the large-scale deployment of semi-synthetic jet fuel globally.

The information contained in this publication will be of significant interest to SBC manufacturers, semi-synthetic jet fuel manufacturers, all those involved in existing jet fuel supply chains, including at airports, through to aircraft operators.
