EN 230:2005 (E) 4 Introduction Whilst this document is written primarily for Automatic Oil Burner Control Systems used on or in appliance for cooking, heating, hot water production, refrigeration, lighting or washing and having, where applicable, a normal water temperature not exceedi
21、ng 105 C, it may be usefully quoted, as a whole or in part, by standards for other equipment. The functional characteristics of the automatic burner control systems, programming units, and their associated flame detector devices, in so far as they are not laid down in this document, are given by the
22、 standards for the appliances for which the automatic burner control systems are intended. This document deals with immunity aspects of Electromagnetic Compatibility (EMC) only. Since automatic burner control systems are intended for use as an integrated or incorporated part of an appliance, further
23、 EMC tests (both immunity and emission) may be required for the intended use. EN 230:2005 (E) 5 1 Scope This document specifies the requirements, operating conditions and test methods for burner control systems for automatic and semi-automatic oil burners with or without fans. It also applies to dua
24、l fuel burners, for use with either oil or gaseous fuels, when operating on oil. This document covers type testing only. This document also applies to automatic burner control systems, programming units or flame detector devices that include additional functions. Automatic burner control systems uti
