The new standard differs from PAS 1188 in several important ways. For example:
• The term ‘resistance’ (rather than ‘protection’) has been used to reflect the scope of the standard better and align it with the new Code of Practice and guidance for Property Flood Resilience (PFR) from the Construction Industry Research and Information Association (CIRIA).
• The designated maximum water depth (DMWD) has been removed so products that can meet greater depths can be tested.
• Additional testing requirements have been introduced to make sure products are exposed to simulated real-life conditions such as cycling testing, dynamic impact testing and overflow testing.
Commercially, the new standard creates new opportunities. In the UK, certification to BS 851188 is supported by The Environment Agency, sponsors of PAS 1188, and it is likely to increase the confidence of buyers.
