This proficiency test is part of our 2024 proficiency testing (PT) program for gas mixtures. The study is covered by our PT provider accreditation (ISO 17043).
Registrations close 1 August 2024.
Study options
Study options available:
- PT study
- PT study with the PT sample as a chemical reference material (CRM)
- calibration standard and supply of a PT sample.
Test materials
We’ll prepare and distribute PT samples in a 5 L gas cylinder with the valve outlet: AS2473 type 20.
We’ll supply these sample cylinders for the:
- PT study at around 25 bar pressure
- PT study with PT sample as a CRM at greater than 80 bar pressure
- calibration standard and supply of a PT sample
- at greater than 80 bar pressure for the CRM
- at around 25 bar pressure for the PT.
Gas samples are based on south-east Australian pipeline natural gas and will contain these components (nominal amounts only):
- Nitrogen, Carbon Dioxide and Propane each at < 2.5 %mol/mol
- Ethane at < 6 %mol/mol
- iso-Butane, n-Butane, iso-Pentane, n-Pentane, and n-Hexane each at < 0.1 %mol/mol
- Methane as balance.
Sample distribution and reporting
We’ll:
- distribute samples by 1 October 2024
- issue the PT report in February 2025.
Once you’ve completed the study you must:
- submit your measurement results by 1 December 2024
- include a brief description of the test method
- include an expanded measurement uncertainty estimate, if applicable.
For both the PT study and the calibration standard and supply of a PT sample, you must then return the sample cylinders by 15 December 2024.
For PT studies with the PT sample as a CRM:
- you don’t have to return the cylinder becomes as it becomes your property
- we’ll give you a CRM certificate after we report the PT results.
