BG 29/2020 is the sixth edition of this popular guide, replacing BG 29/2012.

	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. System contaminants such as mill scale, jointing compound and building debris will inevitably be found in newly fabricated heating and cooling pipework systems. If allowed to remain in the system in sufficient quality, these contaminants will make the system prone to blockages at strainers, control valves and small-bore heat exchangers. They may also initiate further corrosion and encourage the growth of microorganisms.
