Safety and control devices for gas burners and gas burning appliances - Part 3: Pressure and/or flow rate regulators for inlet pressures up to and including 500 kPa, electronic types

This technical document establishes specific safety and control requirements for electronic pressure and/or flow regulators designed for gas burners and gas appliances. It specifically addresses systems where the inlet pressure does not exceed 500 kilopascals, ensuring operational stability and user safety under defined conditions. The scope covers electronic control mechanisms intended to maintain optimal gas flow and pressure levels during combustion processes. Detailed provisions outline performance criteria, testing methodologies, and conformity assessment procedures necessary for the manufacturing and verification of such devices. Compliance with these specifications ensures that the equipment functions reliably within the specified pressure limits while mitigating potential risks associated with gas supply fluctuations. The document serves as a harmonized reference for manufacturers and regulatory bodies, providing clear guidelines on technical implementation. It focuses exclusively on the electronic types of regulators, distinguishing them from other mechanical or pneumatic control systems. Adherence to these technical requirements supports the overall safety framework for gas appliance installations in various environments.
