T/GRTIA 2-2025 Urban rail transit equipment trustworthiness management system application guideline

Scope

Main technical content: This standard aims to assist users of the "Requirements for the Trustworthiness Management System of Urban Rail Transit Equipment" (hereinafter referred to as the "Requirements") in applying the requirements of their trustworthiness management system. This standard provides corresponding guidance for Chapters 4 to 10 of the "Requirements". If there is a direct correspondence between certain provisions of the "Requirements" (such as a), b), c) etc.) and the provided guidance, an explanation is given in the corresponding provisions of this standard. Regarding the "Requirements", this standard provides examples of what organizations can do, but does not add new requirements. The examples given in this standard are not prescriptive, but merely illustrative of what organizations might do, which may not necessarily be suitable for every organization. The "Requirements" contain requirements that can be objectively audited or evaluated. This standard provides examples, descriptions, and optional items that help organizations implement a trustworthiness management system and enhance its connection with the organization's overall management system. Risk refers to the degree of uncertainty inherent in a trustworthiness management system. All systems, processes, and functions involve risks. Adopting a risk-based mindset ensures that these risks are identified, considered, and controlled in the design and application of a trustworthiness management system. In terms of an organization's ability to achieve its trustworthiness objectives, not all processes of the trustworthiness management system exhibit the same level of risk. Some processes of the trustworthiness management system require more careful and formal planning and control than others. This standard only addresses the issues covered by the "Requirements" and clarifies possible misunderstandings of the "Requirements".
