18、LAND STANDARD _ HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2.90: Particular requirements for commercial microwave ovens FOREWORD This standard was prepared by the Joint Standards Australia/Standards New Zealand Committee EL-002- Safety of Household and Similar Electrical Appliances and
19、Small Power Transformers to supersede AS/NZS 60335.2.90:2002 and its amendment 1 (May 2004), from the date of publication. It constitutes a technical revision. Changes in this edition concern requirements for microwave ovens without a cavity door and with transportation means that are intended for c
20、ommercial use only for the heating of food and beverages. The objective of this Standard is to provide manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with safety requirements designed to give the user protection against hazards that might occur durin
21、g normal operation and abnormal operation of the appliance and which may be used as the basis for approval for sale or for connection to the electricity supply mains in Australia and New Zealand This Standard is an adoption with national modifications and contains the full text of the third edition
22、of IEC 60335-2-90, Household and similar electrical appliances Safety - Part 2-90: Particular requirements for commercial microwave ovens and has been varied as indicated to take account of Australian and New Zealand conditions. It is to be used in conjunction with the latest edition of AS/NZS 60335
23、.1, Household and similar electrical appliances Safety - Part 1: General requirements and its Amendments. It was established on the basis of AS/NZS 60335.1:2002. This part 2 supplements or modifies the corresponding clauses of AS/NZS 60335.1 (referred to as part 1 in this part 2) so as to convert it
24、 into the Australian/New Zealand Standard: Safety of commercial microwave ovens. NOTE 1 When “Part 1” is mentioned in this standard, it refers to AS/NZS 60335.1. 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
25、states “addition“, “modification“, or “replacement“, the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or i
26、nvolve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. NOTE 3 The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman type. Words
27、in bold in the text are defined in clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in bold. 5 The numbering of clauses, subclauses, notes, tables, figures and annexes follows that of IEC 60335-2-90 Ed 3. To allow for the introduction of additional ma
28、terial by the IEC, the numbers 101 to 200 have been reserved. To allow for additional material to be introduced by Australia and New Zealand, the numbers 201 to 300 are used to number further clauses, subclauses, notes, tables and figures in part 1. The numbers 301 to 400 are used to number further
29、clauses, subclauses, notes, tables and figures in this part 2. Additional annexes are lettered ZA, ZB and so on. This scheme has been introduced to reduce the likelihood of the IEC and Australia and New Zealand using the same identifier for different purposes. The use of the word VOID indicates that
30、 the IEC text is not used in Australia or New Zealand. The use of this word also avoids the need to renumber, clauses, notes, tables and figure if an earlier clause, note, table or figure is not used. Where relevant the normative references and the bibliography are reformatted to indicate the Austra
31、lia/New Zealand standard that is equivalent to the IEC standard or ISO standard to which reference is made. As this Standard is reproduced from an International Standard, the following applies: (a) Its number does not appear on each page of text and its identity is shown on the cover and title page
32、only. (b) In the source text “this International Standard“ should read “this Australian/New Zealand Standard“. A full point substitutes for a comma when referring to a decimal marker. Variations to IEC 60335-2-90 Ed 3 are indicated at the appropriate places throughout this standard. Strikethrough (e
33、xample) identifies IEC tables, figures and passages of text which, for the purposes of this Australian/New Zealand standard are deleted. Where Australian/New Zealand tables, figures or passages of text are added, each is set in its proper place and identified by shading (example). Added figures are
34、not themselves shaded, but are identified by a shaded border. Variations made to IEC 60335-2-90 Ed 3 form the Australian variations for the purposes of the IECEE scheme for recognition of testing to standards for safety of electrical equipment (the CB scheme). These variations have been incorporated
35、 in the body of the standard. They are listed in Annex ZZ for easy reference. 6 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 internati
36、onally 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 manufacturers instructions. It also covers abnormal situations that can be expected in practice and takes into account
37、the way in which electromagnetic phenomena can affect the safe operation of appliances. This Standard takes into account the requirements of AS/NZS 3000 as far as possible so that there is compatibility with the wiring rules when the appliance is connected to the supply mains. However, national wiri
38、ng rules may differ. If an appliance within the scope of this Standard also incorporates functions that are covered by another part 2 of AS/NZS 60335, the relevant part 2 is applied to each function separately, as far as is reasonable. If applicable, the influence of one function on the other is tak
39、en into account. 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. An appliance that complies with the text of this Standard will not necessarily be considered to comply with the safe
40、ty 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 exa
41、mined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the Standard. The essential safety requirements in AS/NZS 3820 that could be applicable to commercial microwave ovens are covered by this Standard. 7 COPYRIGHT
42、HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2.90: Particular requirements for commercial microwave ovens 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with: ? the safety of microwave ovens with a cavity door intended for commercial use, the
43、ir rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. ? the safety of combination microwave ovens with a cavity door, the requirements for which are contained in Annex AA. ? the safety of microwave ovens without
44、 a cavity door and with transportation means that are intended for commercial use only, for the heating of food and beverages, the requirements for which are contained in Annex BB Microwave ovens, covered by annex BB, have transportation means for moving the microwave load through the microwave oven
45、. Requirements for tunnel microwave ovens and several types of microwave vending machines are covered. NOTE 101 In annex BB a microwave oven without a cavity door and with transportation means is described as a microwave oven. All clauses of this standard apply to these appliances unless otherwise s
46、pecified in Annex BB. This international standard also takes into account ordinary persons having access to the removing area of the vending machine. NOTE 102 The appliance may be built into a vending machine, in which case IEC 60335-2-75 may also be applicable. NOTE 103 Appliances that use non-elec
47、trical energy are within the scope of this standard. In general, this standard does not take into account the use of appliances by young children or infirm persons without supervision; playing with the appliance by young children. This international standard does not take into account the use of a m
48、icrowave oven without a cavity door and with transportation means by ordinary persons except in the vicinity of entrance and exit ports. NOTE 104 The rationales for particular microwave exposure conditions and measures related to microwave energy being confined by an open structure are in Annex BB.
49、NOTE 105 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; for appliances intended to be used in tropical countries, special requirements may be necessary; 8 COPYRIGHT in many countries, the national health authorities, the national authorities responsible for the protection of labour and similar authorities specify additional requirements; in many countries, national authorities specify addition
