Road Vehicles - Functional Safety - Part 2: Management of
Functional Safety
1 Scope
This document specifies the requirements for functional safety management for automotive applications, including the following:
---project-independent requirements with regard to the organizations involved (overall safety management), and
---project-specific requirements with regard to the management activities in the safety lifecycle, i.e. management during the concept phase and the product development phases (at the system, hardware and software level), and regarding production, operation, service and decommissioning.
This document is intended to be applied to safety-related systems that include one or more electrical and / or electronic (E/E) systems and that are installed in series production road vehicles, excluding mopeds.
This document does not address unique E/E systems in special vehicles such as E/E systems designed for drivers with disabilities.
NOTE: other dedicated application-specific safety standards exist and can complement this document, or vice versa.
Systems and their components released for production, or systems and their components already under development prior to the publication date of this document, are exempted from the scope of this edition. This document addresses alterations to existing systems and their components released for production prior to the publication of this document by tailoring the safety lifecycle depending on the alteration. This document addresses integration of existing systems not developed according to this document and systems developed according to this document by tailoring the safety lifecycle.
This document addresses possible hazards caused by malfunctioning behavior of safety-related E/E systems, including interaction of these systems. It does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy and similar hazards, unless directly caused by malfunctioning behavior of safety- related E/E systems.
This document describes a framework for functional safety to assist the development of safety- related E/E systems. This framework is intended to be used to integrate functional safety activities into a company-specific development framework. Some requirements have a clear technical focus to implement functional safety into a product; others address the development process and can therefore be seen as process requirements in order to demonstrate the capability of an organization with respect to functional safety.
This document does not address the nominal performance of E/E systems.
Appendix A provides an overview on objectives, prerequisites and work products of this document.

during the safety lifecycle to support the safety argument.
NOTE 1: in the case of a distributed development, the safety case of the item can be a combination of the safety cases of the customer and of the suppliers, which references evidence from the work products generated by the respective parties. Then the overall argument of the item is supported by arguments from all parties. The interfaces between the customer and a supplier are defined in a Development Interface Agreement (see GB/T 34590.8-2022, Chapter 5).
NOTE 2: to support safety planning according to 6.4.6, the intended safety arguments can be identified prior to work products becoming available. To support progressive functional safety assessments according to 6.4.12.3 the safety case can be released progressively as work products are generated to provide evidence for the safety arguments. 6.4.9 Confirmation measures
6.4.9.1 The functional safety of the item and its elements shall be confirmed, based on: a) confirmation reviews to judge whether the key work products, i.e. those included in Table 1, provide sufficient and convincing evidence of their contribution to the achievement of functional safety, considering the corresponding objectives and requirements of GB/T 34590, in accordance with Table 1 and 6.4.10;
NOTE 1: the confirmation reviews are performed for those work products that are specified in Table 1 and required by the safety plan.
b) a functional safety audit to judge the implementation of the processes required for functional safety, in accordance with Table 1 and 6.4.11; and
NOTE 2: the reference processes required for functional safety are defined in GB/T 34590. The processes pertaining to an item or element are defined through the activities referenced or specified in the safety plan.
c) a functional safety assessment to judge the achieved functional safety of the item, or the contribution to the achievement of functional safety by the developed elements, in accordance with Table 1 and 6.4.12.
NOTE 3: the aim of the independence defined in Table 1 is to ensure an objective, unbiased viewpoint and to avoid conflict of interest. The use of the term “independence” in this document relates to organizational independence.
NOTE 4: guidance for the confirmation measure is given in Appendix D.
NOTE 5: a report that is a result of a confirmation measure includes the name and revision number of the work products or process documents analyzed (see GB/T 34590.8-2022, Chapter 10).
NOTE 6: if the item changes subsequent to the completion of confirmation measures, then the
