Call for Development Group Members – AS 7703 Signalling Power Supplies

The Rail Industry Safety and Standards Board (RISSB) is seeking nominations from people to join a Development Group to develop a new Australian Standard – AS 7703 Signalling Power Supplies.

Power supply systems for railway signalling frequently use ‘floating’/earth-free supplies to minimise the risks of false operation of safety-critical systems that could lead to major safety incidents. While this is not precluded by AS3000, there is often uncertainty about good practise in designing, installing and maintaining such systems.

This Standard will assist with design and delivery of signalling system power supply systems that match signalling equipment requirements. The intention is improved maintainability, reliability and availability of systems whilst addressing safety of persons and signal systems.

This Standard will provide guidance for design and performance criteria for a distributed power network for signalling requirements.

How to contribute
Stakeholders and interested parties are invited to submit nominations for subject matter experts to join this Development Group to contribute to the overall depth and quality of the Standard.

Development Group membership is voluntary and requires the support of your organisation to attend and contribute. There will be 4 meetings over the development period – 2 face-to-face (expected in December 2018 & February 2019) and 2 teleconferences (October 2018 & May2019). Further information on the responsibilities of a Development Group member can be obtained from the RISSB website.

All nominations and enquiries are to be submitted to dmckell@rissb.com.au.

As part of your nomination, can you please provide a brief detailing your contact details, your interest in this development (materially affected party, subject matter expert, etc.), and any other information which might support your participation.

Your information will assist us in ensuring a balanced representation from all major interest categories in the development of this document.

Closing date for nominations Friday, 28th September 2018.
