Brand: BSRIA

The current edition of BSRIA’s Pre-commission Cleaning guide is BG 29/2021. It was revised in partnership with the CSCA with input from an industry steering group, members of which are listed in the guide. It supersedes all previous editions of the guide. It is BSRIA’s intention that, in normal circumstances, BG 29/2021 should be used in preference to any superseded editions of the guide. Superseded versions of the guide are still available (see Revision History above) as they provide useful reference information for older projects. Users of BG 29/2021 should be aware that it is a guide, not a regulation. It is for individual project teams to decide whether to follow the guidance, and this should be made clear in project documentation.

This guide has been superseded by BG 29/2021 Pre-Commission Cleaning of Pipework Systems amended 6th edition.

Pre-commission cleaning is the process of bringing a closed heating or cooling system to a satisfactory state for commissioning and ongoing maintenance of water quality.

Changes from BG 29/2012 to BG 29/2020 include guidance on topics that were not previously covered including:

cleaning precautions for thin-walled carbon steel pipes,
closed-loop pre-treatment cleaning (CPC) procedures,
pre-treatment options described in German directive VDI 2035,
corrosion monitoring solutions,
heat networks and low carbon systems.

Example design diagrams showing flushing and cleaning provisions have been updated to include common features of modern variable-flow heating and chilled water systems.

Furthermore, section 3 of the guide has been revised to give greater clarity at the inspection and witnessing stages. Onus is placed on cleaning specialists to produce a sampling and analysis plan with target limits for various water quality parameters based on their knowledge of system materials, fill water and the ongoing water treatment regime
