Cleanliness quality class
The BSRIA guide to 'Commissioning Air Systems' (BG 49/2024), written by by Keith Barker and published by BSRIA in March 2024, explains how to commission ducted air distribution systems in buildings. It was originally published in 2013, then 2015 with the latest update in 2024.
It defines cleanliness quality class for the purposes of the guide as: ‘A quantifiable level of duct cleanliness that should be achieved prior to handover. It should be specified as high, medium or low prior to contract commencement based on a British & European Standard.’
