This guide has been superseded by BG 29/2021 Pre-Commission Cleaning of Pipework Systems amended 6th edition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