ASTM D4054 Service
Aviation OEMs allow new SAF types to be used with their equipment by implementing the ASTM D4054 standard practice for the evaluation and approval of new aviation turbine fuels. This practice is data intensive. The EU SAF Clearing House provides everything needed for a SAF technology developer to have their product undergo ASTM D4054.
The main elements of our ASTM D4054 Service Pillar are:

One-Stop-Shop
A hyper-efficient impartial one-stop-shop connection between the SAF technology developer and the OEMs.
The EU SAF Clearing House offers to manage the relationship such that the information needed is complete, fit for purpose and in line with OEMs' expectations, facilitating a "right first time" outcome.

Fuel Testing Data
A large quantity of data acquired by specified test methods is required for implementation of ASTM D4054, and this data must be reputable.
Our D4054 Service Pillar provides comprehensive fuel testing data, ensures data quality, efficiency of service, and research report writing.

Linking Services
The EU SAF Clearing House links SAF technology developers and SAF producers with key stakeholders as appropriate; OEMs, US & UK Clearing Houses, European Union Aviation Safety Agency (EASA), Federal Aviation Administration (FAA), Joint Inspection Group.

Guidance & Support with Costs
The EU SAF Clearing House encourages those who seek to valorise new feedstocks to SAF, and those who seek to introduce innovative conversion technologies into the market.
Depending on the details of the feedstock and conversion technology, a SAF producing technology may be compatible to an existing Annex of ASTM D7566 and UK Defence Standard 91-091. In other cases, those details will indicate a new type of SAF, which will require regulatory evaluation & approval by the implementation of ASTM D4054.
The EU SAF Clearing House will make this interpretation and if necessary, involve the additional expertise of our stakeholding partners through our Linking Services.
Where ASTM D4054 is required, the EU SAF Clearing House has already arranged all the services needed, and will work with the SAF technology developer to make these available. In cases where a strong benefit to the ReFuelEU Aviation mandates is apparent, the EU SAF Clearing House may be able to assist with the costs associated with ASTM D4054.

Streamlines Processes
The ASTM D4054 standard practice is a necessary barrier to approve new SAF types for use, but it is a high barrier.
Working under the direction of the OEMs and in collaboration with the US & UK Clearing Houses, the EU SAF Clearing House leads a number of projects to improve & streamline the practice, and build open access capabilities to make the evaluation & approval barrier less effort to surpass (e.g. complete ASTM D4054 testing capacity in the EU, standardised reporting templates, etc.).

ASTM D4054 Prescreening Service
“Prescreening” is early-stage expert advice on SAF candidate compatibility with conformity to an existing annex of ASTM D7566 or to positive ASTM D4054 evaluation. Prescreening is outside the ASTM D4054 process, designed as an initial lower barrier gateway for SAF evaluation requiring only very small volumes of SAF candidate.
Prescreening tools and procedures enable early estimates of critical fuel properties followed by direct measurement of these properties to guide fuel processing development utilising very small volumes of fuel only. This service minimises cost, program risk and time requirements.
As prescreening occurs before the fuel enters the formal ASTM D4054 evaluation process, it allows feedback to the SAF producer to further develop or fine-tune their production process to be confident of a positive evaluation in ASTM D4054, saving time and cost.
Test Centres
The EU SAF Clearing House maintains an open collaboration with testing facilities around Europe. All test centres interested in becoming part of the EU SAF Clearing House are invited to contact us.
