Specifies general safety requirements for approval and test purposes for ignition transformers for gas and oil burners. This Standard is an adoption with national modifications and contains the full text of IEC 61558-2-3:1999.

Replacement:This International Standard deals with all aspects of safety such as electrical, thermal and mechanical aspects.This part of IEC 61558 AS/NZS 61558 applies to fixed single-phase air-cooled (natural or forced) associated transformers (incorporated or not) used in the ignition system of gas and oil burners, having a rated supply voltage not exceeding 1 000 V a.c. and a rated frequency not exceeding 500 Hz. The rated output current does not exceed 500 mA a.c.NOTE 1 Due to the national safety law, in Japan the rated output current does not exceed 50 mA.The no-load output voltage and the rated no-load output voltage does not exceed 15 000 V a.c.This standard applies to transformers where double or reinforced insulation between circuits is not required by the installation rules or by the appliance specification.NOTE 2 The transformers are intended to be associated with equipment to provide voltages different from the supply voltage for the functional requirement of the equipment. The safety insulation may be provided (or completed) by other features of the equipment, such as the body.This standard is applicable to dry-type transformers. The windings may be encapsulated or non encapsulated.NOTE 3 For transformers filled with liquid dielectric or pulverised material, such as sand, additional requirements are under consideration.NOTE 4 Attention is drawn to the fact that for transformers intended to be used in tropical countries special requirements may be necessary; for the purposes of this standard, Australia and New Zealand are not considered to be tropical; in locations where special environmental conditions prevail, particular requirements may be necessary.This standard also applies to transformers incorporating electronic circuits. This standard does not apply to external circuits and their components intended to be connected to the input and output terminals or socket-outlets of the transformer.NOTE 5 Electronic ignition transformers are under consideration.
