This standard made the following editorial changes.

--- Chapter 2 normative references deleted IEC 62236-4, because of previous IEC 62236 (all parts) column items, including the IEC 62236-4;

--- Chapter 2 normative references documents, EN50124, EN50125, EN50155 and has by IEC TC9 CENELEC TC9X cooperation strategy into IEC 60571, the full text is replaced with IEC 60571 EN50155, IEC 62497-1 replaced EN50124-1, IEC 62498-1 instead of EN50125-1, IEC 62498-3 instead of EN50125-3;

--- Increased number 5.1 to the next level to meet the Chinese habit of scheduling;

--- Appendix E, Table E.1 ~ referenced table E.10 statement removes a number table after table header to simplify reading.

The standard proposed by the People's Republic of China Ministry of Railways.

This standard by the national electric traction equipment and systems Standardization Technical Committee (SAC/TC278) centralized.

This standard is mainly drafted by. Tongji University, the Ministry of Railways Institute of Standards and Metrology.

Participated in the drafting of this standard. Zhuzhou CSR Times Electric Co., Ltd., Beijing Research and Design Institute whole way communication signals.

Introduction

Safety related electronic signaling system including hardware and software aspects. For the installation of complete safety-related system, the entire system life cycle Period, these two aspects should be taken into account. In this standard defines security-related needs of the entire system hardware and other related needs the IEC standard definition.

Mutual recognition is for general rather than application-specific approval.

As the standard of evidence relates to the acceptance of safety-related systems, such evidence includes. the acceptance phase should be completed before the life cycle of activity; additional planned activities after the acceptance stage also need to perform. Therefore, to prove the safety of the entire life cycle it is met.

This standard is concerned what the evidence submitted. In addition to be recognized as suitable for addition to, this standard does not specify who is to perform the necessary work, because in Under different environmental conditions are not the same.

For an electronic device includes a programmable safety-related systems, software, additional conditions are defined in the IEC 62279.

Additional safety-related data communication needs to be defined in the IEC 62280.

1 Scope

This standard applies to rail traffic signal applications in safety-related electronic systems (including subsystems and equipment).

This standard relates to the relationship between the scope of IEC and other international standards is shown in Fig.

This standard applies to all safety-related rail signaling system/subsystem/equipment. But in the IEC 62278 and this standard as defined in Hazard analysis and risk assessment process is necessary for all rail traffic signal system/subsystem/devices, in order to determine security needs begging. If the analysis indicates the presence (ie, non-safety-related case) no security requirements, and if this conclusion is not affected by subsequent changes Then may terminate this safety standard application.

This standard applies to both the overall signal system specification, design, construction, installation, inspection, operation, maintenance and modification/expansion phase, but also for the overall signaling system of individual subsystems and equipment. Appendix C includes electronic hardware components related procedures.

This standard applies to generic (including application regardless of the type of application and special category) subsystems and equipment, it should also apply to specific with the system/subsystem/equipment.

This standard does not apply to the existing system/subsystem/equipment (ie before they created this standard has been accepted). But as long as reasonable and Reality, change and expansion of existing systems, subsystems and devices of this recommended standard.

This standard applies to rail traffic signal applications specifically designed and manufactured system/subsystem/equipment. As long as reasonable and in line with real Occasion, it should also apply to those as a safety-related system components common signal or industrial equipment (such as power, modem, etc.). to Less, shall provide evidence that.

--- Do not rely on this device to achieve security;

--- This device can be relied upon to implement safety-related functions.

This standard applies to the functional safety of rail traffic signal system, it does not involve personal occupational health and safety issues, this aspect of its His standard discussion.
