Amendment No. 1 to AS 1824.1—1995 Insulation co-ordination Part 1: Definitions, principles and rules

REVISED TEXT

The 1995 edition of AS 1824.1 is amended as follows; the amendment should be inserted in the appropriate place.

SUMMARY: This Amendment applies to Appendix ZZ.

Published on 5 March 1997.

Page 21 Table ZZ2

Delete Note to Table ZZ2 and replace with:

NOTES:

1. If values in brackets are considered insufficient to prove that the required phase-to-phase withstand voltages are met, additional phase-to-phase withstand tests are needed.
2. For single wire earth return (SWER) systems used in Australia, the nominal voltages are 12.7 kV and 19.1 kV. These are r.m.s. line to earth voltages chosen as approximations to the phase to neutral voltages of 22 kV and 33 kV systems for which the highest voltages for equipment (U_m) are 24 kV (r.m.s.) and 36 kV (r.m.s.) respectively. The insulation level for these SWER systems may be chosen from Table ZZ2 according to the applicable highest voltage for equipment (U_m).

Review of Australian Standards. 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.

Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine ‘The Australian Standard’, which subscribing members receive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards.

Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian 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 92215.

Manual of uniform traffic control devices

Part 2: Traffic control devices for general use

PREFACE

This Standard was prepared by the Standards Australia Committee on Road Signs and Traffic Signals to supersede AS 1742.2—1986, Manual of uniform traffic control devices, Part 2: Traffic control devices for general use. It is one of a series of thirteen Standards as follows:

A further Part, Traffic signals, is in the course of preparation.

This Standard deals with traffic control devices for general use and is applicable to all roads other than freeways. It has been divided into two main sections, one dealing with controls at intersections and the other with controls between intersections. The latter section has been further divided by relating the devices to specific traffic situations and problem areas between intersections.

This edition of this Standard contains a number of amendments which reflect changes in practice which have evolved since the earlier edition of the Standard was published. The more significant changes are as follows:

1. The former ‘hybrid’ signs No Left (Right, U) Turn and Two-way Traffic, have been changed to symbol only signs, by deleting the words from the sign. The NO ENTRY sign now has the words within the symbol.
2. Sight distance warrants for use of STOP signs are now included.
3. Additional symbols for intersection warning signs are now permitted. They are listed in Appendices F and G.
4. Route names on direction signs are always to be in a white panel.
5. Overhead lane indication signs are to have upward rather than downward pointing arrows.
6. Finger boards indicating destinations now have white letters on standard green background with white chevron. The black and white finger board is now to be used only as a rural road name board.
7. The chevron alignment sign has been introduced for the delineation of substandard curves.
8. Climbing lanes (as opposed to overtaking lanes) are now to be used only on one-way carriageways, except for very short sections on two-way carriageways, now known as turnouts for heavy vehicles.
9. Additional warning and information signs for long and very steep descents are now included.

(j) Yellow is no longer an acceptable option for barrier lines. All lines for moving traffic are now white.

(k) Material relating to traffic signals has now been omitted from this Standard and will shortly be published in a new Part of AS 1742.

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.

The Department of Transport and Works, Northern Territory did not agree to the publication of Amendment No. 1.
