BG 29/2012 provides the latest guidance on pre-commission cleaning reflecting new British and European standards.
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.
This guide provides the latest thinking and good practice cleaning techniques. It 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.
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.
Contents include: - Design considerations - Inspection and witnessing - Installation considerations - System dynamic flushing - Chemical cleaning procedure - Connections between new and existing systems
