New Standard for Flood Protection

The end of 2019 saw the publication of the world’s first national standard BS851188 for flood protection products. It built on the previous Publicly Available Standard (PAS1188) that has been developing since its launch in 2003 and also from commercial standards such as FM2510, which are often used in US and Asia.

The ongoing development of standards is essential as the industry continues to innovate. Back in 2003, no one was considering flood doors; it was all manually attached barriers then. But as the industry evolved to meet the needs of property owners and insurers, the drive for automatic, passive or normally closed solutions became apparent.

While manufacturers have been investing in these new solutions, the standard has lagged behind the innovation until this new publication, which sees a number of important changes.

There have been several key changes to the standard:
Products are now classified as either Part 1 or Part 2. Part 1: Building products incorporating building aperture products, building skirts and wall sealant systems. Part 2: Perimeter barrier systems incorporating temporary and demountable barrier products.
The maximum height of the designated maximum water depth (DMWD) has been removed to allow products that are capable of meeting greater design depths to be tested where testing facilities exist. This means that for the first time, commercial clients can demand BS certification to meet the specification of their design.
Maximum leakage rates in both parts 1 and 2 remain unchanged. This means that the BS requires superior leakage performance of building aperture products compared with FM2510. However, there are additional test requirements which have been incorporated to ensure that the primary function of products are considered and to simulate exposure to real life condition, and to harmonise with existing standards for these types of product.
These include:

Cycle testing and operating forces for flood doors and windows.
Dynamic impact testing for doors, windows, building aperture barriers and temporary and demountable barriers.
Overflowing testing for temporary and demountable barriers to ensure the safety of these products in these conditions.
Standards in the flood resistance market are important as they drive up the quality of flood protection products offered and Aquobex will be the first company to retest its existing range of certified products such as Floodguard Clip-in Barrier, Floodguard Screw-in Barrier and Floodguard uPVC Door.
