Review of Standards. 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which subscribing members receive, and which give details of new publications, new editions and amendments, and of withdrawn Standards.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 95900.

PREFACE

This Interim Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee TE/7, Human Exposure to Electromagnetic Fields, to supersede, in Australia, AS 2772.1—1990 and, in New Zealand, NZS 6609.1:1990, Radiofrequency radiation, Part 1: Maximum exposure levels—100 kHz to 300 GHz.

This Interim Standard is based on the International Radiation Protection Association (IRPA) Specific Absorption Rate (SAR) Guidelines. This edition covers an extended frequency range down to 3 kHz.

The term 'informative' has been used in this Interim Standard to defined the application of the appendix to which it applies. An informative appendix is for information and guidance only.

While this document has been the subject of public comment and has met the consensus requirements for publication, given the level of public interest in this subject Standards Australia and Standards New Zealand has decided to issue this document as an Interim Standard to allow further committee review and public comment before being finalised. The particular areas the Committee will be reviewing are as follows:

• The treatment of non-thermal effects.
• The appropriateness of proposed radiation levels which are based on current World Heath Organization (WHO) recommendations.
• The proposed measurement methods of time and spatial averaging.

Standards Australia and Standards New Zealand invite comment on this Interim Standard from persons and organizations concerned with this subject. The date for expiry of comment is 5 March 1999 at which (or earlier) this Interim Standard will be confirmed, withdrawn or revised in the light of comments received.

During the life of this document the Committee will monitor all comment as it is received.

Attention is drawn to the fact that this document is an Interim Australian/ New Zealand Standard and should be regarded as a development Standard liable to future alteration.
