BS 851188-1:2019

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.Cross References:BS EN 12600:2002BS 493:1995+A1:2010BS EN 124BS EN 1191 BS EN 12046-1BS EN 12046-2Equality Act 2010BS 85500Construction, Design and Management Regulations 2015Fire Safety (Scotland) Regulations 2006Gas Safety (Installation and Use) Regulations 1998BS EN 13564-1BS EN 12056-1Regulatory Reform (Fire Safety) Order 2005BS 851188-2Fire Safety Regulations (Northern Ireland) 2010BS 7775BS EN ISO/IEC 17025Disability Discrimination Act 1995 (Northern Ireland)BS 6349-1-2
