Specifies particular safety requirements for approval and test purposes. It is to be read in conjunction with AS/NZS 3350.1:1994. This Standard is technically equivalent to and reproduced from IEC 335-2-61:1992.

This clause of part 1 is replaced by:This standard deals with the safety of thermal storage room heaters for household and similar purposes which are intended to heat the room in which they are located, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.So far as is practicable, this standard deals with the common hazards presented by appliances which are encountered by all persons in and around the home.This standard does not in general take into account:- the use of appliances by young children or infirm persons without supervision;- playing with the appliance by young children.NOTES1 Attention is drawn to the fact that:- this standard only applies to self-contained thermal storage room heaters, however it may be used as a guide, in so far as it reasonably applies, to determine the requirements and test specifications for other thermal storage room heaters;- for heaters incorporating direct acting heating elements IEC 335-2-30 is also applicable;- for heaters intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;- for heaters intended to be used in tropical countries, special requirements may be necessary;- in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.2 This standard does not apply to:- heaters designed exclusively for industrial purposes; - heaters incorporated in the building structure;- central heating systems; - installations for heating floors; - heaters for saunas (IEC 335-2-53);- heaters intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
