60335-2-16:2003+A2:2012 EN 60335-2-16:2003+A2:2012 (E) INTRODUCTION It has been assumed in the drafting of this International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturer's instructions It also covers abnormal situations that can be expected in practice and takes into account the way in which electromagnetic phenomena can affect the safe operation of appliances This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility with the wiring rules when the appliance is connected to the supply mains However, national wiring rules may differ If an appliance within the scope of this standard also incorporates functions that are covered by another part of IEC 60335, the relevant part is applied to each function separately, as far as is reasonable If applicable, the influence of one function on the other is taken into account When a part standard does not include additional requirements to cover hazards dealt with in Part 1, Part applies NOTE This means that the technical committees responsible for the part standards have determined that it is not necessary to specify particular requirements for the appliance in question over and above the general requirements This standard is a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject NOTE Horizontal and generic standards covering a hazard are not applicable since they have been taken into consideration when developing the general and particular requirements for the IEC 60335 series of standards For example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surfaces, are not applicable in addition to Part or part standards An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by these requirements An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard Licensed copy: University of Auckland Library, University of Auckland Library, Version

2-16: Particular requirements for food waste disposers Scope This clause of Part is replaced by the following This International Standard deals with the safety of electric food waste disposers for household and similar purposes, their rated voltage being not more than 250 V Appliances not intended for normal household use but that 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 As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home However, in general, it does not take into account ! – persons (including children) whose • physical, sensory or mental capabilities; or • lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction; – children playing with the appliance " NOTE 101 Attention is drawn to the fact that – for appliances intended to be used in vehicles or on board ships or aircraft, additional 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, the national water supply authorities, and similar authorities; – the installation of food waste disposers may be restricted or not allowed NOTE 102 – This standard does not apply to portable food waste disposers; – food waste disposers of the incinerator type; – appliances intended exclusively for industrial or commercial purposes; – appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas) Normative references This clause of Part is applicable Definitions This clause of Part is applicable except as follows Licensed copy: University of Auckland Library, University of
