The NCC Primary References Set contains the editions of the Standards as referenced in the NCC. In some instances, these are not the same as the current edition of the Standard subsequently published or updated by Standards Australia. New editions of Standards which are primary references in the NCC will only be included when the NCC is updated. From time to time, Standards may be subject to Amendments, in which case, the former content (including text, figures and equations) will be noted and the former content will be accessible within the various access types on the Standards Store. We recommend that users make their own enquiries as to which editions of Standards are referenced in the NCC or other relevant regulatory instruments at a specific point in time.
