To maintain their currency, all Standards are periodically
6、reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.
7、 Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Australia web site at .au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue. Alternatively, both organizations publish an ann
8、ual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their resp

19、AL SUPERVIS on 17 May 20073 COPYRIGHT FOREWORD This standard was prepared by the Joint Standards Australia/Standards New Zealand Committee EL-002- Safety of Household and Similar Electrical Appliances and Small Power Transformers, to supersede, in part, AS/NZS 3108, Chapter 2, two years from publica
20、tion. The objective of this Standard is to provide manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with safety requirements for the design, manufacture and testing of shaver transformers which can form the basis for approval by regulatory authorities
21、This Standard forms the first edition of AS/NZS 61558.2.5 Safety of power transformers, power supply units and similar - Part 2.5: Particular requirements for shaver transformers. This Standard is an adoption with national modifications and contains the full text of the first edition of IEC 61558-2-
22、5:1997, Safety of power transformers, power supply units and similar - Part 2-5: Particular requirements for shaver transformers and shaver supply units 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
23、of AS/NZS 61558.1 and its amendments. It was established on the basis of the first edition (2001) of that standard. This part 2 supplements or modifies the corresponding clauses of AS/NZS 61558.1 so as to convert it into the Australian/New Zealand Standard: Safety requirements for shaver transformer
24、s. Where a particular subclause of part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. Where this Standard states “addition“, “modification“ or “replacement“, the relevant text in part 1 is to be adapted accordingly. NOTE 1 Subclauses, notes, tables and figures wh
25、ich are additional to those in part 1 are numbered starting from 101. Annexes, which are additional to those in part 1 are lettered AA, BB, etc. Annex ZZ is for information only. NOTE 2 In this Standard the following print types are used: requirements: in arial type; test specifications: in italic t
26、ype; notes: in small arial type; Words in bold in the text are defined in clause 3. The numbering of clauses, subclauses, notes, tables, figures and annexes follows that of IEC 61558-2-5:1997. To allow for the introduction of additional material by the IEC, the numbers 101 to 200 have been reserved.
27、 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 clauses, subclauses, notes, tables and figures in this part 2
28、. 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 the IEC text is not used in Australia or New Zealand. The us
29、e 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. As this Standard is reproduced from an International Standard, the following applies: Accessed by ISONET - CHINA STATE BUREAU OF TECHNICAL SUPERVIS on 17 May 20
30、074 COPYRIGHT (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“. (c) A full point substitutes for a comma when referring to a decimal
31、marker. Variations to IEC 61558-2-5:1997 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 tables, fig
32、ures 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 61558-2-5:1997 form the Australian variations for the purposes of the IECEE scheme for recog
33、nition 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 17 May 20075 COPYRIGHT AUSTRALIA/NE
