AS 1299, 1st, 2022 – Electrical equipment for mines and quarries – Explosion-protected three-phase restrained and bolted cable coupling devices for working voltages up to and including 11 kV
AS 1299 was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee EL-023, Electrical Equipment in Mines and Quarries, to supersede AS/NZS 1299:2009, Electrical equipment for mines and quarries — Explosion-protected three-phase restrained plugs and receptacles for working voltages up to and including 3.3 kV and AS/NZS 1300:2009, Electrical equipment for mines and quarries — Bolted explosion-protected three-phase cable coupling devices. After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this document as an Australian Standard rather than an Australian/New Zealand Standard.
The objective of this document is to provide requirements and guidance for explosion-protected threephase restrained plugs, receptacles and cable coupling devices to manufacturers, users, regulatory authorities and associated interests and for use with other related Australian/New Zealand Standards and relevant mining regulations. It also is to allow for the use of existing compatible cable coupling systems and for the introduction of new non-compatible cable coupling systems.
This document differs from the previous edition in that it combines the previous AS/NZS 1299 and AS/NZS 1300 into one document (now designated AS 1299).
The terms “normative” and “informative” are used in Standards to define the application of the appendices to which they apply. A “normative” appendix is an integral part of a Standard, whereas an “informative” appendix is only for information and guidance.
