IEC 62290‑3:2025 specifies the system architecture for urban guided transport management and command/control systems (UGTMS) as defined in IEC 62290‑1 and IEC 62290‑2, and the allocation of functions and requirements defined in IEC 62290‑2 to the different UGTMS subsystems (designated as system constituents in IEC 62290‑1 and IEC 62290‑2), for use in urban guided passenger transport lines and networks. The IEC 62290 series specifies the functional, system and interface requirements for the command, control, and management systems intended to be used on urban, guided passenger transport lines and networks. These systems are designated herein as urban guided transport management and command/control systems (UGTMS). UGTMS cover a wide range of operations needs from non-automated (GOA1) to unattended (GOA4) operation. A line may be equipped with UGTMS on its full length or only partly equipped. The IEC 62290 series does not specifically address security issues. However, aspects of safety requirements may apply to ensuring security within the urban guided transit system. The main objectives of this series are as follows: * to provide a baseline system description and functional requirements specification for a transport authority to use in a request for proposal, * to provide recommendations for those transport authorities wishing to acquire an interoperable or interchangeable system. It is the responsibility of the transport authority concerned to decide on how to apply the IEC 62290 series and to take into account their particular needs. The IEC 62290 series is also intended to support applications for upgrading existing signalling and command control systems. In this case, interchangeability and compatibility could be ensured only for the additional UGTMS equipment. Checking the possibility for upgrading existing equipment and the level of interoperability is the responsibility of the transport authority concerned. This document is applicable for new lines or for upgrading existing signalling and command control systems. This document is applicable to applications using * continuous data transmission, * continuous supervision of train movements by train protection profile, and * localisation by onboard UGTMS equipment (reporting trains), and optionally by external wayside (and optionally onboard) device. The functional allocations of the UGTMS subsystems are mandatory (forming a sort of core system) or optional, according to the mandatory/optional functions and requirements defined in IEC 62290‑2. This document is applicable as a basis to define FIS and FFFIS. For specific applications, some elements can be added to meet the requirements coming from additional functions or equipment. This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the last maintenance of IEC 62290‑1 is taken into account, in particular the changes made for describing the external environment of UGTMS; b) the last maintenance of IEC 62290‑2 is taken into account, as IEC 62290‑3 is using the requirements defined in the latter. Therefore, the document reflects the deleted functions and requirements in IEC 62290‑2, and also the new functions and requirements.

1 Scope
1.1 General
The aviation, space, and defence industries rely on the development and manufacture of complex products comprised of multiple systems, subsystems, and components each designed by individual designers (design activities) at various levels within the supply chain. Each design or manufacturing activity controls various aspects of the configuration and specifications related to the product. When a change to design or process is requested or required, the change is typically required to be evaluated against the impacts to the entire system.
Proposed changes to design data/information that the design activity identifies to be minor and have no effect on the product requirements or specifications, have the potential to be implemented and approved, where authorized to do so, but requires notification. Changes that affect customer mandated requirements or specifications shall be approved prior to implementation. In many cases, the design activity is not conducted by the DAH or design authority. The design activity may be several layers below the design approval. Irrespective of where the design activity is conducted in the supply chain, notification is required. The typical change notification flow is presented in Figure 1.
[Figure 1]
Submitting NOC data either electronically or conventionally on paper is subject to the terms and conditions of the customer’s contract. This also includes, where applicable, data access under the regulations of export control.
The process of exchanging, coordinating, and approving NOC data varies with the multiple relationships and agreements among all organizations concerned. An objective of this document is to provide the definition of a data set that can be integrated into any form of communication (e.g. electronic data interchange, submission of conventional paper forms). A sample form can be found in the Supply Chain Management Handbook (SCMH).
If all or part of this document is contractually invoked, design organizations and design holders (i.e. the organization responsible for the product end item design) that have responsibility for change management of products used on other higher-level designs shall use the information and processes defined in this document for submitting change notifications.
1.2 Application
This document defines the common NOC requirements for aviation, space, and defence organizations. The requirements that a design organization are to use when submitting a NOC to the customer for either change authorization or notification are included herein. A NOC informs the customer of physical or functional (e.g. design, material, software, maintenance) changes or any associated process changes to an established baseline configuration.
Retention of the NOC establishes a means of configuration control and captures the evolution of the part. This requirement is of utmost importance in commercial/civil aviation products where changes to type certificated products are mandated by regulations; however, these same concepts are also required in defence and space applications per contractual requirements.
Where there are changes to items which the organization does not have design input or is not permitted to make any changes to the design [e.g. build to print, Technical Standard Order (TSO) articles] then change requests are to be formally submitted to the customer and approved via the customer’s change request process.

1.1 General
This part of the IEC 60255 series specifies the requirements for electromagnetic compatibility for measuring relays and protection equipment. It is applicable to measuring relays and protection equipment and combinations of devices to form schemes for power system protection including the control, monitoring, communication and process interface equipment used with those systems.
Tests specified in this document are not required for equipment not incorporating electronic circuits, for example electromechanical relays.
The requirements specified in this document are applicable to measuring relays and protection equipment in a condition representative of how new equipment is provided by the manufacturer. All tests specified are type tests only.
1.2 Emission
This document specifies limits and test methods, for measuring relays and protection equipment in relation to electromagnetic emissions which might cause interference in other equipment.
These emission limits represent electromagnetic compatibility requirements and have been selected to ensure that the disturbances generated by measuring relays and protection equipment, operated normally in substations and power plants, do not exceed a specified level which could prevent other equipment from operating as intended.
Test requirements are specified for the enclosure, auxiliary power supply ports, input/output ports, signal/control ports and wired network ports.
1.3 Immunity
This document specifies the immunity test requirements for measuring relays and protection equipment in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges.
These test requirements represent the electromagnetic compatibility immunity requirements and have been selected so as to ensure an adequate level of immunity for measuring relays and protection equipment, operated normally in substations and power plants.
NOTE 1 Product safety considerations are not covered in this document.
NOTE 2 In special cases, situations will arise where the levels of disturbance could exceed the levels specified in this document, for example where a hand-held transmitter or a mobile telephone is used close to measuring relays and protection equipment. In these instances, special precautions and procedures could have to be employed.
