NOTE 1 The PAS test conditions (see Annex B) represent typical conditions that can be experienced during a flood. This includes testing the flood protection 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 polluted 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 can be obtained from the Flood Protection Association, the National Flood Forum, 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 flood protection product and system are specifically designed and/or tested to withstand such stresses.

NOTE 5 Temporary flood protection products are normally installed in conjunction with a pumping arrangement to remove any excessive water.

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.
