AQA 24-34 pipeline natural gas

October 2024

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. 

Cost

The cost to participate is:

  • PT study $1,600 
  • PT study with PT sample as a CRM $5,100
  • calibration standard and supply of a PT sample $5,750.

The price includes:

  • goods and services tax (GST)
  • delivery to Australian sites.

You must pay extra for:

  • return freight
  • all international freight and duty charges.
