What is EN ISO 15848-2:2015 ?

EN ISO 15848-2:2015 is a critical technical standard that aims to minimize the risk of fugitive emissions from industrial valves used in hazardous fluid processes. The standard provides guidelines for testing and evaluating valve packing, ensuring the safety and efficiency of various industries. In this article, we will provide a comprehensive overview of EN ISO 15848-2:2015, including its scope, mandatory requirements, and implementation and compliance strategies.

Scope and Application

EN ISO 15848-2:2015 is a global technical standard that applies to the design, manufacture, and testing of valve stem packings used in process equipment. The standard is relevant to various industries, including oil and gas, chemical, and petrochemical sectors, where the use of hazardous fluids may pose a risk to human health and the environment.

To comply with the requirements of EN ISO 15848-2:2015, valve manufacturers must implement effective design, material selection, and testing procedures. They must also account for factors such as temperature variations, pressure differentials, and media compatibility when designing and manufacturing valves. The goal is to ensure that valves can effectively seal off any potential leaks, preventing fugitive emissions from escaping and causing harm.

Mandatory Requirements

EN ISO 15848-2:2015 lays out several mandatory requirements for valve manufacturers, including the following:

* Leakage rate testing: Valve manufacturers must conduct a thorough leakage rate testing to ensure that their products do not allow any fugitive emissions to escape.

* Packaging design: Valve manufacturers must design their valves to minimize the risk of fugitive emissions.

* Material selection: Valve manufacturers must select materials that are compatible with the media used in the process and minimize the risk of corrosion or leaching.

* Testing: Valve manufacturers must conduct thorough testing to verify that their products meet the requirements of EN ISO 15848-2:2015.

Implementation and Compliance

To implement the requirements of EN ISO 15848-2:2015, manufacturers must perform the following steps:

* Conduct a thorough review of the standard to ensure compliance.

* Identify potential sources of fugitive emissions and implement strategies to minimize their risk.

* Conduct leakage rate testing to ensure compliance with the standard.

* Select compatible materials for their valves and ensure that they are tested for compatibility with the media used in the process.

* Conduct thorough testing to verify that their products meet the requirements of EN ISO 15848-2:2015.

* Document their testing results and their compliance with the standard.

Conclusion

EN ISO 15848-2:2015 is a critical technical standard that applies to the design, manufacture, and testing of valve stem packings used in hazardous fluid processes. By understanding the requirements of this standard, manufacturers can ensure their products meet the necessary criteria to achieve certification, minimizing the risk of fugitive emissions and protecting the health and welfare of workers and surrounding communities.
