To keep abreast of progress in industry, Australian 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.

Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. This Standard was issued in draft form for comment as DR This is a free 7 page sample. AS The Standard is identical with and has been reproduced from IEC , Telecontrol equipment and systems, Part 4: Performance requirements.

IEC has decided to apply a new numbering system, the series, to all its existing and future publications, including amendments to existing Standards.

As a consequence, IEC has modified the bibliographic references in its databases to accord with the new numbering system. All IEC publications issued since the beginning of will carry references in terms of the series numbering.

Publications printed earlier than will continue to carry the old series of numbers. This Standard is identical with a pre document therefore it uses the old series of numbers.

The objective of this Standard is to provide manufacturers and users of telecontrol equipment and systems with a set of rules for accessing and specifying performance requirements in order to determine the requirements for a particular telecontrol system to be used in Australia.

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 only on the cover and title page.

Except where the Copyright Act allows and except where provided for below no publications or software produced by Standards Australia may be reproduced, stored in a retrieval system in any form or transmitted by any means without prior permission in writing from Standards Australia. Permission may be conditional on an appropriate royalty payment. Requests for permission and information on commercial software royalties should be directed to the head office of Standards Australia.

Standards Australia will permit up to 10 percent of the technical content pages of a Standard to be copied for use exclusively in-house by purchasers of the Standard without payment of a royalty or advice to Standards Australia. Standards Australia will also permit the inclusion of its copyright material in computer software programs for no royalty payment provided such programs are used exclusively in-house by the creators of the programs.

Care should be taken to ensure that material used is from the current edition of the Standard and that it is updated whenever the Standard is amended or revised. The number and date of the Standard should therefore be clearly identified. The use of material in print form or in computer software programs to be used commercially, with or without payment, or in commercial contracts is subject to the payment of a royalty.

This policy may be varied by Standards Australia at any time.
