The Jet A-1 Proficiency Test (PT) Scheme helps laboratories demonstrate ongoing competence and support accreditation by comparing results against a global participant base, aligned with test methods used in Defence Standard 91-091 and ASTM D1655.
Frequency: Bi-annual (two rounds per year).
Sample source: Jet A-1 fuel sourced from a supply network serving UK airports and terminals, providing a true representation of Jet A-1.
Why take part?
What you’ll receive
Each participating laboratory receives a detailed report including:
Statistical processing: Results are processed using statistical procedures in BS EN ISO 4259-1 & 4259-3. Data is pre-screened using GESD in accordance with ISO 4259-1; any outliers removed after review are clearly indicated and excluded from the dataset.
Sample handling and integrity: All operations are carried out at Stanhope-Seta’s ISO 17025 & ISO 17034 accredited Richardson Laboratory.
