For many years, EN 746-2 was the key reference standard for combustion safety in industrial furnaces across Europe. With the introduction of ISO 13577, the regulatory framework has significantly evolved.
This is not simply a formal update, but a shift from component-based safety toward a system-wide approach covering the entire installation: the furnace, auxiliary equipment, control architecture, and operator interface.
Many furnaces originally designed under EN 746-2 today show typical limitations, such as safety logic embedded within the process PLC, insufficient separation between control and safety functions, or incomplete software documentation. ISO 13577 requires a more structured risk assessment and a clearer, more robust control architecture.
As a result, compliance often involves more than software adjustments. It frequently requires rethinking the overall system design.
When managed properly, the transition becomes an opportunity to modernize the control system, improve combustion stability, and integrate advanced energy monitoring tools.
With strong expertise in industrial furnace automation and combustion systems, we support this transition in a structured way, turning regulatory compliance into measurable technical improvement.
