What is BS EN 13497-2:2018+A1:2021

BS EN 13497-2:2018+A1:2021 is a technical standard that specifies the requirements and test methods for the design, construction, and performance of pressure-regulating devices. This standard applies to both manual and automatic pressure regulators used in water supply systems.

Scope and Key Requirements

The scope of BS EN 13497-2:2018+A1:2021 covers pressure regulators used in residential, commercial, and industrial applications. It provides guidance on pressure setting, flow capacity, pressure drop, shut-off accuracy, durability, resistance to elevated temperatures, and other key requirements essential for optimal functionality and safety of pressure-regulating devices.

Testing and Compliance

To ensure compliance with BS EN 13497-2:2018+A1:2021, pressure regulators must undergo rigorous testing processes. These tests include pressure cycle tests, endurance tests, temperature cycling tests, leakage tests, and accuracy tests. Manufacturers need to provide documentation proving their products' compliance, including detailed test reports and technical specifications.

Advantages and Benefits

Adhering to BS EN 13497-2:2018+A1:2021 offers several advantages and benefits. Firstly, it ensures the quality and reliability of pressure-regulating devices, leading to improved performance and longevity. Secondly, compliance with this standard enhances consumer safety by preventing excessive pressures that could damage pipes, appliances, or cause injury. Lastly, regulatory compliance allows manufacturers to demonstrate their commitment to quality and meet legal requirements in various markets.
