Scope: 1 Scope This British Standard specifies requirements for the designation, testing, factory production control , installation manual, deployment instructions, user manual and marking for different types and configurations of flood resistance products . This British Standard is applicable to flood resistance products intended for use in the temporary sealing of building apertures and entrances to properties, including boards, skirt and wall sealant systems , and flood doors, in the event of static flood water rising above a minimum level of 540 mm above aperture threshold level, except where they are designed to completely cover or replace small apertures, such as airbricks or air vents. The flood resistance products are expected to be effective at flood heights from ground level to the designated maximum water depth (DMWD). It covers wall aperture closure systems and foam products. Skirt and wall sealant systems are used in the temporary sealing of the above or below ground external faces of buildings and properties. This British Standard specifies the method of testing and product performance. The range of building aperture sizes covered is a nominal width of up to 6 000 mm. For skirt and sealant systems the range of building sizes covered is governed by the system constraints, but theoretically the system could be installed to provide protection to any size of building. NOTE 1 The hydrostatic pressures exerted by floodwater can cause sudden or long-t...
