DIN EN 12067-2:2015-12

This European Standard specifies the safety, construction and performance requirements for electronic fuel/air ratio control (ERC), electronic fuel/air ratio supervision (ERS) and electronic fuel/air ratio trim (ERT) intended for use with burners and appliances burning gaseous or liquid fuels. It also describes the test procedures for evaluating these requirements and specifies information necessary for installation and use. This European Standard is applicable to - closed loop fuel/air ratio controls, 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. This European Standard applies to ERC, ERS or ERT that can be tested independently, as well as part of an appliance or a burner.
