Frequency and Benefits

This global proficiency testing scheme is run annually in May.

See below for the suite of gas mixtures available.

Companies with multiple teams need only purchase one set of gases and can submit multiple sets of results per round for a small additional fee per team. In addition, after the initial purchase, each participant will only pay for cylinder refilling for future rounds and EffecTech will carry out cylinder re-tests when required so there are no additional responsibilities or costs for the customer. The analysis takes place at a time and location suitable to the participants (within the timescale of the scheme) so there is no need for overnight stays or equipment transport.

Reporting


Participants are required to report the composition and an estimate of the uncertainty of the gas where appropriate using the reporting template.

Evaluation


Evaluation will be using ISO 17043 approved methods including En ratio and Z scores.

Confidentiality


As mandated by ISO 17043, all data including participants and performance will be kept strictly confidential.  Only the submitting laboratory will receive feedback on their performance.  Performance data will be reported to the whole group anonymously.
