This proficiency test is part of our 2024 proficiency testing (PT) program for gas mixtures. The study is covered by our accreditation as a PT provider (ISO 17043).
Registrations close 1 October 2024.
Test materials
We’ll prepare and distribute each PT sample in a 0.5 L constant pressure cylinder (CPC).
Liquefied petroleum gas (LPG) samples will contain these components (nominal mole fractions only):
- Propane: 60% to 80%
- n-Butane: 15% to 25%
- iso-Butane: 15% to 25%
- Ethane: ≤ 2 %
- Pentane: ≤ 2 %.
Reference values for the comparison are traceable to the SI (International System of Units) registered in the KCDB (Key Comparison Database).
