What is EN ISO 15848-1:2019?

EN ISO 15848-1:2019 is a technical standard that provides guidelines and requirements for the testing and qualification of valve stem packings for industrial applications. It sets forth the criteria for determining the fugitive emissions performance of these packings when used in valves. This standard helps ensure that the valve stem packings meet specific emission limits, which are crucial for minimizing leaks and preventing environmental pollution.

Importance of EN ISO 15848-1:2019

The release of gases or vapors from industrial equipment, such as valves, can have harmful effects on the environment and human health. Fugitive emissions, which refer to the unintended leakage of fluid or gas through sealing systems, contribute significantly to air pollution. EN ISO 15848-1:2019 plays a vital role in mitigating fugitive emissions by recommending rigorous testing procedures and setting emission limits for valve stem packings. Complying with this standard helps industries reduce their environmental footprint and ensures safer working conditions for employees.

Testing and Qualification Process

To meet the requirements of EN ISO 15848-1:2019, valve stem packings undergo extensive testing to assess their emissions performance. The testing process involves subjecting the packings to different operating conditions, including temperature, pressure, and cycling. Leakage rates are measured using specialized equipment and techniques to determine if the packings comply with the standard's specified emission limit levels. Packings that meet these requirements are qualified for use in industrial valves.

Benefits and Applications

Adhering to EN ISO 15848-1:2019 offers several benefits to both manufacturers and users of valve stem packings. Manufacturers can demonstrate the quality and reliability of their products by obtaining certification to this standard. Users can have confidence in the performance of these packings, knowing that they have been rigorously tested and meet international emission standards. This standard has a wide range of applications across industries such as oil and gas, chemical processing, and power generation, where the control of fugitive emissions is crucial.
