Scope of standard

This part of IEC 61558 deals with the safety of ignition transformers for gas and oil burners. Ignition transformers incorporating electronic circuits are also covered by this standard. Unless otherwise specified, from here onward, the term transformer covers ignition transformers for gas and oil burners. This part applies to fixed single-phase air-cooled (natural or forced) associated dry-type transformers used in the ignition systems of gas and oil burners. The windings may be encapsulated or non-encapsulated. The rated supply voltage does not exceed 1 000 V a.c., and the rated supply frequency and the internal operational frequency do not exceed 500 Hz. The rated short-circuit output current does not exceed 500 mA a.c. The no-load output voltage or the rated output voltage does not exceed 15 000 V a.c. This part is not applicable to external circuits and their components intended to be connected to the input and output terminals or socket-outlets of the transformers. Transformers covered by this part are used in applications where double or reinforced insulation between circuits is not required by the installation rules or by the end product standard.
