This updated guide incorporates industry feedback from nearly twenty years of flushing and cleaning using BSRIA's Pre-Commission Cleaning of Pipework guides. It is a revised edition of Application Guide AG 1/2001.1 (2004), 2nd edition, containing all the recommendations for design, installation, system flushing and chemical cleaning of pipework systems and a section dealing with the issues raised when connecting new pipework to existing pipework. The Guide is intended for designers and installers of recirculating heating and cooling systems and does not apply to hot and cold water supplies. Includes tests for pseudomonas. In particular, 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-commissioning cleaning contractors. Note that additional guidance on the sampling and analysis of system water, including during the pre-commissioning phase of the building life-cycle, will be included in a new British Standard.
