Description / Abstract:


This Joint Australian/New Zealand Standard was prepared by Joint Technical Committee EL- 002 - Safety of Household and Similar Electrical Appliances and Small Power Transformers to supersede AS/NZS 61558.2.5:2003 and its amendments three years from the date of its publication. During this period it is anticipated that regulatory authorities will approve transformers for shavers, power supply units for shavers and shaver supply units to either standard.

This standard will run in parallel with AS/NZS 3194:1993 and its amendments from the date of its publication.

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 transformers for shavers, power supply units for shavers and shaver supply units which can form the basis for approval by regulatory authorities.

This Standard incorporates Amendment No. 1 (November 2012). The changes required by the amendments are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected. Where an application date other than immediate is applicable to an amendment the date of application (DOA) and the date of withdrawal (DOW) if relevant, is indicated by the marginal bar against the part affected.

The text IEC 61558-2-5 Ed 2, prepared by IEC Technical Committee 96, was submitted to the Standards Australia/Standards New Zealand Combined Procedure (dual public comment and committee vote) for adoption of the IEC standard as a Standards Australia/Standards New Zealand joint standard.

This Standard is an adoption with national modifications of the second edition of IEC 61558-2- 5, Safety of transformers, reactors, power supply units and combinations thereof - Part 2-5: Particular requirements and test for transformers for shavers, power supply units for shavers and shaver supply units. It has been varied as indicated to take account of Australian and New Zealand conditions.

This part 2 has to be used in conjunction with the latest edition of AS/NZS 61558.1 Safety of Power Transformers, Power Supplies, Reactors and Similar Products – Part 1: General requirements and tests and its amendments. It was established on the basis of the 2008 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.

The main changes consist of updating this part in accordance with AS/NZS 61558.1:2008, adding power supply units to the scope and adding additional requirements for shaver supply units taken from AS/NZS 3194.

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 and test for transformers for shavers, power supply units for shavers and shaver supply units.

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.

NOTE 1 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 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.;

– subclauses, notes and annexes that are additional to those in the IEC standard are prefixed with the letters AZ.

NOTE 2 The 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 3.

p NOTE 3 In this document, p is used in the margin to indicate instructions for preparing a consolidated version.

The essential safety requirements in AS/NZS 38201 that could be applicable to requirements for transformers for shavers, power supply units for shavers and shaver supply units are covered by this standard.

The national variations to the IEC 61558-2-5 Ed 2 form the Australian and New Zealand national variations for purposes of the IECEE scheme for recognition of results of testing to standards for safety of electrical equipment (the CB scheme).
