EN 13611:2019, Clause 1 is replaced by the following: This document specifies the safety, design, construction and performance requirements, and testing for electronic fuel/air ratio control systems (ERC), electronic fuel/air ratio supervision systems (ERS) and electronic fuel/air ratio trim systems (ERT) intended for use with burners and appliances burning gaseous or liquid fuels. It also describes the procedures for evaluating these requirements and specifies information necessary for installation and use. This document is applicable to: – closed loop fuel/air ratio control systems, see 3.101; – fuel/air ratio supervision systems, see 3.102; – closed loop fuel/air ratio trim systems, see 3.103; and does not differentiate into classification by heat input. NOTE The documents for burners, appliances or processes which use ERC, ERS or ERT can override the requirements of this document.
