What is BS EN 13564-3 –Quality assurance of anti-flooding devices for buildings about? 
Anti-flooding devices are installed either directly in the pipework of a drainage system or incorporated in a floor gully intended to protect buildings from internal flooding, i.e. rooms which are below the flood level.
BS EN 13564 is a series of European Standard that discusses anti-flooding devices for buildings. BS EN 13564-3 is the third part of the BS EN 13564 series, which aims to provide quality assurance for anti-flooding devices for buildings.
BS EN 13564-3 specifies the requirements for anti-flooding devices for buildings to ensure conformity of these products with EN 13564-1.
Who is BS EN 13564-3 - Quality assurance of anti-flooding devices for buildings for?  
BS EN 13564-3 on quality assurance of anti-flooding devices for buildings form is relevant to: 
- Manufacturers of anti-flooding devices
- Architects
- Product designers
- Quality control and testing personnel 
- Inspection authorities
- Local bodies
Why should you use BS EN 13564-3 - Quality assurance of anti-flooding devices for buildings? 
BS EN 13564-3 provides guidance on type testing and factory production control when it comes to the manufacturing of anti-flood devices for buildings. The purpose of factory production control is to ensure constantly, that production of anti-flooding devices is in conformity with the technical requirements of EN 13564-1.
Reference standards for test methods to demonstrate conformity to requirements of materials, dimensions, tightness and appearance is also provided in BS EN 13564-3.
Third party control is also discussed in BS EN 13564-3. The purpose of the third party control is to demonstrate the ability of the manufacturer to manufacture products which continuously meet the requirements of EN 13564-1 and to give independent certification to these products.
Thus, if you are a manufacturer of anti-flooding devices, compliance with BS EN 13564-3 requirements can help demonstrate the reliability and performance of your products. Devices satisfying the requirements are deemed to be durable and hence can be used for a longer period of time.
