New guidance document provides information on anticipated changes to the next edition of EN 15004-1

Since its initial publication in 2008, the EN 15004-1 standard (Fixed firefighting systems - Gas extinguishing systems - Part 1: Design, installation and maintenance) has been largely based on ISO 14520-1. The text of the  2022 edition of ISO 14520-1, will be the basis of a proposed revision to EN 15004-1. A new guidance document prepared by Euralarm’s Extinguishing Section identifies the key changes that are expected to appear in the revised EN 15004-1. The guidance is designed to prepare specifiers, insurers, systems designers, and end users an early indication of what to expect once the revision to EN 15004-1 is completed.

While designed to provide guidance on the revision to EN 15004-1, they key changes follow exactly the amendments/additions made in ISO 14520-1. The key changes proposed concern agent safety information, actuator placement indication, enclosure pressure venting, effects of noise in sensitive areas, clarification of hazard classification, scaling factors, and evaluation criteria for new agents.

The Euralarm Extinguishing Section believes the changes to EN 15004-1 are important enhancements and welcomes the improvements to the safety and efficacy of gaseous fire extinguishing systems that will arise from the revision to EN 15004-1.
