BS 851188

On 27 March 2019 the British Standards Institution (BSI) opened a public consultation exercise to gather feedback on the draft of the newly formed BS 851188. This is expected to replace the existing Publicly Available Specification PAS 1188 standards for flood resistance products.

Drafts of both of these new standards are currently live for public comment and consultation through the BSI’s website. These can be accessed at:

The public consultation phase was expected to be open until 28 May 2019.

These standards look at a series of products for flood resistance, which seek to manage water entry into a building, allowing for appropriate conditions. With a wide range of products now available on the market including both active measures (requiring manual implementation in the event of a flood) and passive measures (not requiring manual implementation in the event of a flood outside of normal everyday use), this standard will help identify products that have met an industry recognised British Standard.
