AQA 24-31 workplace and mine safety

April 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 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.
