Compliance with is essential for several reasons: BS EN 772-1:2011+A1:2015 - BSI Knowledge

In the UK, under the Construction Products Regulation (CPR), if you install a drainage channel that does not comply with BS EN 7721, you may be found liable in the event of structural failure or personal injury.

The standard details several critical steps to ensure accuracy and repeatability across different laboratories:

If you are a specifier or purchaser, do not just ask for a – ask for the manufacturer’s Test Report and Declaration of Performance . Follow these steps:

The procedure for BS EN 772-21 is straightforward:

These standards are critical for a wide range of professionals in the construction industry, including:
