Proficiency Test Scheme

Jet A-1 Proficiency Test Scheme

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?
  • Strengthen Quality Control and confidence in routine Jet A-1 test results using independent inter-laboratory comparison
  • Support audits and accreditation goals
  • Clear performance metrics to identify strengths, trends and opportunities for improvement
  • Cost-effective and globally representative, drawing on an established international user base
