The price for participation of a single test team in the Hydrogen Chloride & Water Vapour Proficiency Testing Scheme is £1,500.00 + VAT. Participants can either operate a single or individual sampling trains for HCl and water vapour.

Participants will be required to provide offline analysis results within 20 working days of the measurement taking place.

Participants will also be able to make real-time continuous measurements of HCl and water vapour from a single instrument, if they desire.

The total maximum sample gas extraction rate per participating team must not exceed 40 litres per minute.

Participants will be invited to set up instrumentation the day before testing, between 4pm and 6pm only.
