Scope

This PAS specifies requirements for the designation, testing, factory production control, installation documentation and marking for different types and configurations of flood protection products. This PAS is applicable to flood protection products intended for use in the temporary sealing of building apertures and entrances to properties, in the event of static flood water rising up to a level between 600 mm and 900 mm above ground level, except where they are designed to completely cover or replace small apertures, such as air-bricks or air vents. This PAS is intended for use in the UK or locations with similar exposures, i.e. where there is a temperate climate and advanced warning of flooding is available. This PAS specifies the method of testing and an allowable leakage rate. The range of building aperture sizes covered is a nominal width of up to 2 400 mm. NOTE 1 The hydrostatic pressures exerted by floodwater can cause sudden or long-term structural damage and undermine the foundations of a building or cause leakage through the walls, floor or sub-floor, unless the building is specifically designed to withstand such stresses. The actual water level that can be safely retained by the external walls will depend upon the construction, type, form, age and condition of the walls. It is recommended that a suitably qualified building surveyor, architect or structural engineer inspects the external walls, before any flood protection product for building apertures is installed. NOTE 2 Flood protection products are not normally intended to prevent water more than 600 mm to 900 mm above the level of the ground surrounding the property from entering the building. NOTE 3 The PAS test conditions represent typical conditions that can be experienced during a flood. This includes testing the flood protection product for leakage under static water levels, waves up to 0.1 m high and parallel currents up to 1.0 m/s. NOTE 4 This PAS does not cover testing with contaminated or saline water, however, product manufacturers are required to provide information about the performance of their products in these conditions (see Annex C). NOTE 5 Conformance of the flood protection product does not mean it is suitable for all situations. If the user is in any doubt as to the suitability of a flood protection product they should seek further guidance as set out in Preparing for floods: Interim guidance for improving the flood resistance of domestic and small business properties [1], or from the Flood Protection Association(www.floodprotectionassociation.org) or other professional advisers. NOTE 6 Extreme loading conditions such as those resulting from turbulent water or from debris impact are not covered by testing in this PAS. If required in these locations, the flood protection product needs to be specifically designed and/or tested to withstand such stresses. NOTE 7 The flood protection products described in this part of PAS 1188 are not intended for installations providing permanent flood protection, and attention is drawn to the need to ensure a safe evacuation of persons in the event of an emergency and to access and egress for persons with impaired movement. These flood protection products are installed or activated in the event of an imminent flood and removed or deactivated as soon as danger from flooding is over. This PAS is not applicable to the testing of foam products, such as those composed with composite polyurethane. This PAS is not applicable to flood protection products for installation around buildings; these are covered by PAS 1188-3. This PAS is not applicable to temporary or demountable flood protection products which are designed to be installed away from and not attached to buildings, including flood protection products intended for installation across driveway entrances and gateways at property boundaries. These are covered by PAS 1188-2 and PAS 1188-4.
