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

5、 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

6、; 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which subscribing members receive, and which give details of new publications, new editions and amendments, and of withdrawn Standards.Suggestions for improvements to Joint Standards, ad

The dimensions for non-metallic sheath thicknesses are based on the values recommended in IEC 502. Certain tests and criteria in this Standard are more stringent tha

16、 coverings, no cable dimension tables are provided owing to the variety of cable constructions that could affect such dimensions.The term s normative and informative have been used in this Standard to define the application of the appendix to w hich they apply. A norm ative appendix is an integral p
