Description of PAS 1188-4:2014 2014

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.

This PAS specifies the method of testing and an allowable leakage rate.

NOTE 1 The PAS test conditions (see Annex B) represent typical conditions that can 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 Flood protection products that conform to this PAS might not be suitable for all locations, exposures and foundation types. Further guidance is set out in Delivering benefits through evidence: Temporary and demountable flood protection guide [2], Six steps to property level flood resilience: Guidance for property owners [9] and guidance can also be obtained from the Flood Protection Association or from the National Flood Forum or Scottish Flood Forum or other qualified professional advisers.

NOTE 4 Extreme loading conditions such as those resulting from turbulent water or static water head (above designated maximum water depth) or debris impact are not covered by testing in this PAS. In these locations the product and system are 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 installation of flood protection products described in this PAS are not intended to provide permanent flood protection. 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 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.
