AS 7513 Rolling Stock Interior Environment

The objective of this Standard is to describe the requirements for the interior environmental specification and performance of rolling stock. The main purpose of the requirements is to provide a safe and comfortable environment on rolling stock for humans.
This ARISO Standard attempts to define good to best environmental practice from existing legislation and other sources to incorporate as mandatory and recommended requirements for Australian rail networks.

Since the previous edition, AS 7722 has been substantially modernised with a wide set of updates that strengthen clarity, usability, and industry harmonisation. The Standard now incorporates updated IEC, EN, AS/NZS, and ACMA-mandated EMC standards published or revised since 2016, introduces a contemporary approach to EMC risk management with improved threat assessment, interface control, and functional safety considerations, and expands and clarifies lifecycle requirements with detailed guidance across design, construction, testing, commissioning, maintenance, and decommissioning. It also provides stronger alignment with legal and regulatory obligations including Radiocommunications, ARPANSA, WHS, RSNL, and electrical safety requirements, and adds more detailed product-specific EMC requirements for rolling stock, signalling, telecommunications, power systems, and system interfaces.

The Standard improves safety by preventing electromagnetic interference related failures in safety critical systems, ensuring compliance with human exposure limits, and strengthening functional safety and risk management throughout the asset lifecycle. It improves interoperability by harmonising EMC requirements nationally, ensuring compatibility across systems, operators, suppliers, and infrastructure, aligning with international EMC standards, and establishing a common assurance and testing framework that supports consistent evidence of EMC performance.

AS 7722 manages EMC risks across the entire rail system lifecycle, including the risk of electromagnetic interference between rolling stock, signalling, communications, electrification, and external systems, the risk of safety critical system failures such as compromised train detection, braking, or interlocking due to EMI, and the risk associated with human exposure to electromagnetic energy, ensuring emissions remain within ARPANSA and ICNIRP limits. By controlling emissions and susceptibility, the Standard helps rail systems operate safely, reliably, and without unintended interference.

Implementation spans people, processes, and systems. For people, the Standard applies across engineering, operations, and assurance functions, requiring role-based EMC competencies for design, maintenance, and assurance personnel. For processes, it requires formal integration of EMC into the safety management system, design and engineering activities, procurement and contract specifications, and risk assessments, supported by a consistent EMC assessment process including design reviews, interface analysis, emissions and immunity testing, and documented compliance evidence. For systems and tools, implementation interacts with enterprise asset management systems, testing and measurement tools, rolling stock registration and configuration systems, and safety risk and quality assurance systems. Organisations should prepare projects and suppliers with clear EMC requirements, templates, and guidance early in the lifecycle, conduct periodic audits of EMC management activities, evidence and maintenance practices to drive continuous improvement and ensure ongoing compliance with AS 7722, and ensure qualifications and competence for personnel involved in EMC design, testing, and analysis as mandated by the Standard.
