The comments were discussed during the Edinburgh meeting in May 1997 and during the Fehraltorf meeting in october 1997, when it was decided to submit a new draft for EN 60335-2-6 to the formal vote. This draft was circulated in August 1998 and was ratified by CENELEC as EN 60335-2-6 on 1999-04-01. This European Standard replaces EN 60335-2-6:1990 + corrigendum June 1991 and its amendments A2:1992, A51:1993 + corrigendum May 1993, A3:1993, A52:1995, A53:1995 and A54:1997. The following dates are applicable: This standard has to be used in conjunction with EN 60335-1, Safety of household and similar electrical appliances, Part 1: General requirements. It was established on the basis of the 1994 edition of that standard. Amendments and revisions of Part 1 have also to be taken into account and the dates when such changes become applicable will be stated in the relevant amendment or revision of Part 1. This Part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the European Standard: Safety requirements for stationary cooking ranges, hobs, ovens and similar appliances. When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies as far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. Subclauses, figures and tables which are additional to those in Part 1 are numbered starting with 101. There are no special national conditions causing a deviation from this European Standard, other than those listed in Annex ZA to EN 60335-1. National deviations from this European Standard are listed in Annex ZB and are in addition to those in EN 60335-1. NOTEThe following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman type. Words in bold in the text are defined in clause 2. When a definition of Part 1 concerns an adjective, the adjective and the associated noun are also in bold. Foreword to amendment A1 The text of amendment 1:2000 to the International Standard IEC 60335-2-6:1997, prepared by the IEC Technical Committee 61, was submitted to the Unique Acceptance Procedure and was approved by CENELEC as amendment A1 to EN 60335-2-6:1999 on 2001-09-01.

If the product has mechanical moving parts, a risk assessment in accordance with the Machinery Directive, 89/392/EEC, 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. 1 Scope This clause of Part 1 is replaced by: This standard deals with the safety of stationary electric cooking ranges, hobs, ovens and similar appliances for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances. NOTE 1Examples of appliances which are within the scope of this standard: stationary grills; stationary griddles; pyrolytic self-cleaning ovens; induction hobs; steam ovens; the electrical part of appliances supplied with energy other than electricity. So far as 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. NOTE 2Attention 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; for appliances 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, the national water supply authorities and similar authorities. NOTE 3This standard does not apply to appliances intended exclusively for industrial 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); portable cooking appliances (IEC 60335-2-9); microwave cooking appliances (IEC 60335-2-25); commercial electric ranges, ovens and hob elements (IEC 60335-2-36); commercial electric griddles and griddle grills (IEC 60335-2-38); commercial electric forced convection ovens, steam cookers and steam convection ovens (IEC 60335-2-42). NOTE 4Requirements for combination microwave ovens are under consideration; meanwhile IEC 60335-2-25 may be used in conjunction with this standard. NOTE Z1For appliances which are supplied with gas, EN 30 is also applicable. 2 Definitions This clause of Part 1 is applicable except as follows 2.2.6 Addition: NOTEFor appliances having more than three heating units per phase, a diversity factor is applied to the rated power input when determining the current used to establish the size of the terminals and the nominal cross-sectional area of the supply cord. The diversity factor F is calculated from the following formula, where N is the number of heating units per phase which can be energized together: Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 13 17:51:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 60335-2-6:1999 6© BSI 02 August 2002 2.2.9 Replacement: normal operation operation of the appliance as specified in 2.2.9.1 to 2.2.9.6. 2.2.9.1 Hob elements other than induction hob elements, are operated with vessels containing cold water. The vessel is made of unpolished commercial quality aluminium, has a flat bottom and is covered with a lid. Thermal controls are adjusted to their highest setting until the water boils and then adjusted so that the water boils gently. Water is added to maintain the level during boiling. NOTE 1The lid is positioned so that steam does not affect the test. In case of doubt, vessels as specified in Figure 101 are used. Induction hob elements are operated with vessels as specified in Figure 102 which contain approximately half their capacity of cooking oil at room temperature. Thermal
