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 March 2024.

Study options

The study options available are:

  • 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 each PT sample in a 5 L gas cylinder with 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 will contain these components (nominal mole fractions only):

  • Carbon Dioxide at ≤ 40 %
  • Methane at ≤ 15 %
  • Ethane at ≤ 5 %
  • Carbon Monoxide at ≤ 200 ppm
  • Nitrogen as balance.

Reference values for the comparison are traceable to the SI (International System of Units) registered in the KCDB (Key Comparison Database). 

Sample distribution and reporting 

We’ll:

  • distribute samples by 1 April 2024
  • issue the PT report in August 2024.

Once you’ve completed the study you must:

  • submit your measurement results by 1 June 2024
  • include a brief description of the test method.

For both the PT study and the calibration standard and supply of a PT sample, you must then return the sample cylinders by 15 June. 

For PT studies with the PT sample as a CRM: 

  • you don’t have to return the sample cylinder 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 $1,450
  • PT study with PT sample as a CRM $3,600
  • calibration standard and supply of a PT sample $4,200.

The applicable price includes:

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

You must pay extra for:

  • return freight
  • all international freight and duty charges.
