What is BS EN 15848

BS EN 15848 is a technical standard that specifies the requirements and testing procedures for industrial valves used in petroleum, petrochemical, and natural gas industries. It sets out the performance levels and defines the criteria for the selection of materials and design to ensure the safe and efficient operation of these valves.

Key Requirements of BS EN 15848

The standard focuses on controlling fugitive emissions from valve packing components, such as stem seals and bonnet gaskets. Fugitive emissions refer to the unintended release of gases or volatile organic compounds (VOCs) into the atmosphere. By reducing fugitive emissions, BS EN 15848 aims to minimize environmental pollution and health hazards that can result from the leakage of hazardous substances.

To meet the requirements of BS EN 15848, valve manufacturers must use specific materials and technologies for the packing and sealing systems. These materials should have low permeability and be capable of withstanding high temperatures and pressures, ensuring a tight seal and preventing any leaks.

Testing Procedures

BS EN 15848 outlines a series of rigorous tests that valves must undergo to ensure compliance with the standard's requirements. These tests evaluate various parameters, including fugitive emissions, pressure and temperature resistance, and durability under different operating conditions.

One of the commonly performed tests is the helium leak test, which measures the amount of helium gas that escapes through the sealing surfaces of the valve. This test helps determine the valve's ability to contain fugitive emissions, as helium has extremely low molecular size and is difficult to trap.

Other tests include high-pressure gas cycling, thermal cycling, and fire-safe testing, all designed to assess the valve's performance in different scenarios and potential emergency situations.

Benefits and Impact

The adoption of BS EN 15848 brings several benefits. Firstly, it promotes environmental sustainability by controlling and reducing fugitive emissions, contributing to a cleaner atmosphere and improved air quality.

Secondly, it enhances the safety of industrial operations by ensuring reliable performance of valves, minimizing the risk of leaks or failures that can lead to accidents. By meeting the requirements of BS EN 15848, valve manufacturers demonstrate their commitment to producing high-quality products that meet international standards.

Lastly, compliance with BS EN 15848 allows businesses to expand their market reach. More industries and organizations worldwide are recognizing the importance of using environmentally friendly and safe equipment, making certification to this standard a valuable asset for valve manufacturers.

In conclusion, BS EN 15848 is a technical standard that sets out the requirements and testing procedures for industrial valves in industries dealing with petroleum, petrochemicals, and natural gas. It aims to minimize fugitive emissions, ensure safe operation, and improve environmental sustainability. Compliance with this standard demonstrates the commitment of valve manufacturers to producing reliable and high-performing products.
