What is BS EN ISO 5208:2021?

BS EN ISO 5208:2021 is a technical specification that sets out the requirements for industrial valves used in various applications. This standard, developed by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO), provides manufacturers, purchasers, and users of valves with guidance on their design, materials, testing, and documentation.

Scope and Application

The scope of BS EN ISO 5208:2021 covers the classification, design, and qualification of valves for use in different industries, such as oil and gas, chemical, and power generation. It applies to valves used for isolation, control, and safety functions. The standard also provides guidelines for the selection and identification of valve types, based on their intended application and performance requirements.

Requirements and Testing

BS EN ISO 5208:2021 defines specific requirements for valve manufacturers related to design criteria, materials, dimensions, marking, and documentation. It emphasizes the need for reliable and safe valve operation. The standard also outlines various testing procedures to validate the performance and integrity of valves. These tests include pressure testing, leakage testing, and endurance testing, among others.

Benefits and Compliance

Compliance with BS EN ISO 5208:2021 ensures that valves meet international standards of quality, safety, and reliability. Manufacturers who adhere to this standard demonstrate their commitment to producing valves that have undergone rigorous testing and validation. By using valves that comply with BS EN ISO 5208:2021, end-users can have confidence in the performance and durability of their industrial systems. Additionally, compliance with this standard enables easier market access, as it is recognized globally.
