19、 TECHNICAL SUPERVIS on 07 Nov 20074 AUSTRALIA/NEW ZEALAND 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- Safet
20、y of Household and Similar Electrical Appliances and 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
21、and with transportation means that are intended for commercial 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 u
22、ser protection against hazards that might occur during 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 modificat
23、ions and contains the full text of the third edition 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 i
24、n conjunction with the latest edition of AS/NZS 60335.1, 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 (refe
25、rred to as part 1 in this part 2) so as to convert it 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
26、 applies as far as is reasonable. When this standard 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 thos
27、e in Part 1; unless notes are in a new subclause or involve 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 specification
28、s: in italic type; notes: in small roman type. Words 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. Accessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on 07 Nov 20075 The numbering of clauses, s
29、ubclauses, notes, tables, figures and annexes follows that of IEC 60335-2-90 Ed 3. To allow for the introduction of additional material 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 us
30、ed to number further clauses, subclauses, notes, tables and figures in part 1. The numbers 301 to 400 are used to number further 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 o
31、f the IEC and Australia and New Zealand using the same identifier for different purposes. The use of the word VOID indicates that 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,
32、 table or figure is not used. Where relevant the normative references and the bibliography are reformatted to indicate the Australia/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,
33、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 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 dec
34、imal marker. Variations to IEC 60335-2-90 Ed 3 are indicated at the appropriate places throughout this standard. Strikethrough (example) identifies IEC tables, figures and passages of text which, for the purposes of this Australian/New Zealand standard are deleted. Where Australian/New Zealand table
35、s, figures or passages of text are added, each is set in its proper place and identified by shading (example). Added figures are 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 fo
36、r recognition of testing to standards for safety of electrical equipment (the CB scheme). These variations have been incorporated in the body of the standard. They are listed in Annex ZZ for easy reference. Accessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on 07 Nov 20076 INTRODUCTION It
37、 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, fi
38、re 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 the way in which electromagnetic phenomena can affect the safe operation of appliances. This St
39、andard 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 wiring rules may differ. If an appliance within the scope of this Standard also incorporates functi
40、ons 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 taken into account. This Standard is a product family standard dealing with the safety of applianc
41、es 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 safety principles of the standard if, when examined and tested, it is found to have other features
42、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
43、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.

46、ransportation 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. Requirements for tunnel
47、 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 specified in Annex BB. Thi
48、s 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-electrical energy are within
49、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 microwave oven without a cavity door and with transportation means by ordinary persons except in the vicinity of entrance and exit ports.
