Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically 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 Standards may also be withdrawn.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.

Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Web Shop at www.standards.com.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 annual 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 respective national Standards organization.

We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover.

PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee TE-003 on Electromagnetic Interference to supersede AS 2344—1980, Limits of electromagnetic interference from overhead a.c. powerlines. It is based on IEC/CISPR Committee draft CISPR/C(Secretariat)71 produced by the International Special Committee on Radio Interference (CISPR). The draft will eventually become an international Standard produced by CISPR Subcommittee C. This Standard maintains the international format and technical coverage.

This Standard incorporates Amendment No. 1 (May 2007). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.

This Standard has been published in advance of international development as the local requirements for realistic limits and methods of test are considered high priority. Alignment of this Standard to an international version will be considered when one becomes available.

The draft from which this Standard originated was developed by an Australian Subcommittee of Committee TE-003, as an extension of work already underway by the Joint Committee which was reviewing AS 2344—1980. The CISPR subcommittee reviewed international developmental work at the same time and adopted the work of Committee TE-003 as the basis for developing the IEC/CISPR draft Standard. The result is that Australia/New Zealand input has been high and Committee TE-003 considered the draft suitably developed as the basis for a publication.

The format of this Standard mirrors that of the CISPR committee draft. However, clause numbering has been changed due to the addition of Clause 2.

Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard.

A1 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.
