EffecTech’s Stack Emissions Proficiency Testing Scheme has been described as “excellent all round” and has participants in the UK and Ireland as well as in the rest of Europe and Asia.
2022 SEPTS scheme
- The 2022 scheme is now open for enrolment until Friday 1 April 2022. To enrol, please visit this page to download the form and instructions.
- Alternatively, you could participate in an on-demand proficiency testing scheme, in which gas mixtures are provided for ‘blind’ measurement. On-demand schemes are available for sulphur, hydrocarbons and emissions testing.

|Mixture types||Amount fraction range (%mol/mol)|
|oxygen in nitrogen||2 to 14|
|carbon dioxide in nitrogen||1 to 10|
|Mixture types||Amount fraction range (μmol/mol)|
|sulphur dioxide in nitrogen||10 to 200|
|propane in 10% oxygen / nitrogen||5 to 50|
|nitric oxide in nitrogen||10 to 500|
|carbon monoxide in nitrogen||20 to 500|
|NO/NO2 in nitrogen||Nitric oxide (NO)||20 to 400|
|Nitrogen oxides (NOx)||25 to 500|
Participants are required to report the composition and an estimate of the uncertainty of the gas where appropriate using the reporting template.
Evaluation will be using ISO 17043 approved methods including En ratio and Z scores.
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.
