Scope

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.

- 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 standard applies to ERC, ERS or ERT that can be tested independently, as well as part of an appliance or a burner.
NOTE 1 European Standards for burners, appliances or processes which use ERC, ERS or ERT can override the requirements of this standard.
NOTE 2 Provisions for production control are not part of this European Standard.
