To keep abreast of progress in industry, Joint Australian/ New Zealand Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary.It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto. Full details of all Joint Standards and related publications will be found in the Standards Australia and Standards New Zealand Catalogue of Publications; this information is supplemented each month by the magazines ‘The Australian Standard’ and ‘Standards New Zealand’, which subscribing members receive, and which give details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Joint Standards, addressed to the head office of either Standards Australia or Standards New Zealand, are welcomed. Notification of any inaccuracy or ambiguity found in a Joint Australian/New Zealand Standard should be made without delay in order that the matter may be investigated and appropriate action taken. This Standard was issued in draft form for comment as DR 97171.

Final Australian edition AS 1102.102— 1989. Jointly revised and designated AS/NZS 1102.102:1997.

It is issued as a Joint Standard to supersede AS 1102.102 — 1989. It is based on but not equivalent to, and reproduced from, IEC 617-2, Graphical symbols for diagrams , Part 2: Symbol elements, qualifying symbols and other symbols having general application . The objective of this Standard is to provide users of electrotechnical documents with symbol elements, qualifying symbols and other symbols having general application for the purposes of uniformity and clarity in presenting electrotechnical diagrams. Accessed by EDITH COWAN UNIVERSITY LIBRARY on 03 Feb 2016 (Document currency not guaranteed when printed) The Part numbers in this series of Standards correspond to equivalent Parts in the IEC 617 series but with ‘100’ added to the IEC 617 Part number. For example, for the Standard IEC 617-2 refer to AS/NZS 1102.102. The symbol numbers within this Standard are the same as the IEC 617 numbers. In AS 1102.101, Graphical symbols for electrotechnical documentation , Part 101: General information and general index, the first part of the symbol number refers to the Part number, e.g. in the index, for symbol 102-01-01, refer to Part 102, symbol 02-01-01. In this Standard, Australian and New Zealand variations have been listed in Appendix ZA and, accordingly, the source text should be amended, supplemented or replaced as required. The changes to the source text are indicated with a marginal bar against each clause, table, figure or part thereof affected. Appendix ZA provides symbols for use in Australia and New Zealand which are additional to, or alternative to, the IEC 617 symbols. The symbols are identified with an ‘A’ in the third part of the symbol number. Appendix ZB contains information which is not contained in Annex A, on the changes from the superseded Australian Standard to this Part of the Standard. The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance. As this Standard is reproduced from an international Standard, the following applies: (a) Its number appears on the cover and title page while the international Standard number appears only on the cover. (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 marker. References to international Standards should be replaced by equivalent Australian or Australian/ New Zealand Standards, as follows: Reference to International Standard Australian or Australian/New Zealand Standard IEC AS 1102 617 Graphical symbols for diagrams 617-1 Part 1: General information, general index.

The information is provided to highlight changes. The changes from the previous edition in this Appendix are for items which differed from the IEC version to suit Australian conditions at the time of the previous edition. The reference in Clause ZB2 to the symbol number is for the 1989 edition of this Part. Accessed by EDITH COWAN UNIVERSITY LIBRARY on 03 Feb 2016 (Document currency not guaranteed when printed) The Symbol 02-02-08 in this Standard has not been made void.102—1989 because TN–S is not normally used in Australia.
