Household and similar electrical appliances - Safety - Part 2-42: Particular requirements for commercial electric forced convection ovens, steam cookers and steam-convection ovens

Deals with the safety of electrically operated commercial forced convection ovens, steam cookers, steam-convection ovens and, exclusive of any other use, steam generators, not intended for household use. The rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. Appliances within the scope of this standard are typically used in restaurants, canteens, hospitals and commercial enterprises such as bakeries, butcheries, etc. The electrical part of appliances making use of other forms of energy is also within the scope of this standard.

Gospodinjski in podobni električni aparati - Varnost - 2-42. del: Posebne zahteve za komercialne električne pečice s prisilnim kroženjem zraka, parne kuhalnike in pečice s kroženjem pare (IEC 60335-2-42:2002) (vsebuje popravek AC:2007)

Standard obravnava varnost električno upravljanih komercialnih pečic s prisilnim kroženjem zraka, parnih kuhalnikov, pečic s kroženjem pare in generatorjev pare (ki so namenjeni izključno tej uporabi), ki niso namenjeni gospodinjski uporabi. Nazivna napetost mora biti manjša od 250 V za enofazne aparate, priključene med fazo in nevtralni vodnik, in 480 V za ostale aparate. Aparati, ki spadajo v področje uporabe tega standarda, se običajno uporabljajo v restavracijah, menzah, bolnišnicah in komercialnih podjetjih, kot so pekarne, mesnice itd. Tudi električni del aparatov, ki uporabljajo druge vire energije, spada v področje uporabe tega standarda.

An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 73/23/EEC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown that
the risks are mainly of electrical origin and consequently this directive is not applicable. However, the
relevant essential safety requirements of the Machinery Directive are covered by this standard together
with the principal objectives of the Low Voltage Directive.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including ind
