Gas/air ratio controls for gas burners and gas burning appliances - Electronic types1 Scope This European Standard specifies the safety, construction and performance requirements for electronic gas air ratio control systems (GARCs) intended for use with gas burners and gas burning appliances. It also describes the test procedures for evaluating these requirements and specifies information necessary for installation and use. This standard is only applicable to closed loop gas air ratio controls (see 3. 1) and does not differentiate
