29/2012 now replaces BG 29/2011

BSRIA has announced the release of the new edition of its guide: Pre-Commissioning Cleaning of Pipework Systems, which it claims is a revised and updated edition, and replaces BG 29/2011. The guide, (BG 29/2012) reflects new British and European standards and clarify certain points that have been raised over the last year, and provides the industry with the latest guidelines and good practice cleaning techniques for commercial hot and cold water services systems in buildings, it added.

According to BSRIA, In particular, the new edition of the guide aims to clarify the roles and responsibilities of the parties, improve the exchange of information between them and provide consistency between service offerings of the pre-commission cleaning contractors.

Pointing out that thorough pre-commission cleaning of pipework systems continues to be important with the adoption of energy-efficient controls strategies that may result in low flow rates, particularly in terminal units with very small orifices in control valves, BSRIA said that pre-commission cleaning is achieved through a process of flushing and chemical cleaning (where required) followed by the addition of biocides and inhibitors. Systems designed and cleaned in accordance with BSRIA’s guidance are far less likely to experience operating problems, it claimed.

BSRIA has listed the contents included in the guide:

• Design considerations
• Inspection and witnessing
• Installation considerations
• System dynamic flushing
• Chemical cleaning procedure
• Connections between new and existing systems

BSRIA has provided the following information: Hard copies of the guide are now available for purchase at £60 or £30 to BSRIA members. Pdf versions are also available for £60 + VAT or free to download for BSRIA members.
