AS/RISSB 7720:2017现行

The main purpose of this Standard is to provide a framework that describes the requirements for the design, construction, commissioning, monitoring, maintenance and decommissioning of signalling equipment enclosures and wiring in Australian railway corridors.The Standard is intended to outline requirements that govern signalling equipment enclosures and their wiring on a whole-of-life approach.The Standard covers a set of requirements to manage the identified industry hazards by identifying risks associated with the signalling equipment enclosures and wiring. This standard only applies if enclosures are assessed as the only practical option for equipment protection at the particular site.Where a signalling enclosure is selected as the preferred enclosure for a location, this Standard provides design requirements for types of free standing enclosures and their wiring for rail signalling equipment.
