This PAS specifies requirements for the designation, testing, factory production control, installation documentation and marking for different types and configurations of flood protection products
intended to be demountable, for use away from buildings, but may be sealed against structures or buildings at section ends, 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.
NOTE 1 The PAS test conditions represent typical conditions that may be experienced during a flood. This includes testing the product on a concrete base for leakage and structural failure under static water levels,
random waves up to 0.1 m high and parallel currents up to 1.0 m/s.
NOTE 2 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 3 Conformance of the product does not mean it is suitable for all locations, exposures and foundation types. If the user is in any doubt as to the suitability of a product to any specific location, they should seek further guidance as set out in Temporary and demountable flood protection:
Interim guidance on use [1] or from the Flood Protection Association (www.floodprotectionassociation.org) or other professional advisers.
NOTE 4 Extreme loading conditions such as those resulting from turbulent water or from debris impact are not covered by testing in this PAS. In these locations the product should be specifically designed and/or tested to withstand such stresses.
NOTE 5 Demountable flood protection products are normally installed in conjunction with a pumping arrangement to remove any excessive leakage.
NOTE 6 The flood protection products described in this part of PAS 1188 are not intended for permanent installation, and attention is drawn to the need to ensure a free passage to persons in the event of an emergency
and to access and egress for persons with impaired movement. These products should only be installed in the event of an imminent flood and should be removed as soon as danger from flooding is over.
This PAS is not applicable to flood protection products for installation across building apertures such as individual doors, windows, air-bricks and air vents or around buildings; these are covered by PAS 1188-1
and PAS 1188-3.
This PAS is not applicable to temporary flood protection products which are not location specific in their use, are intended to be wholly installed during a flood event and wholly removed afterwards; these are covered by PAS 1188-2.
This PAS does not specifically test flood protection products for coastal conditions. Where flood protection products are intended for coastal conditions, advice on suitability should be obtained from the manufacturer.
