This part of GB/T 34590 provides an overview of GB/T 34590, and additional explanations are given to enhance understanding of other parts of this standard. This section has only informative properties, describing the general concepts of GB/T 34590 for easy understanding. This explanation extends general concepts to specific content. This standard applies to safety-related systems including one or more electrical and electronic systems installed in mass-produced passenger vehicles. This standard does not apply to specific electrical and electronic systems on special purpose vehicles, for example, vehicles designed for disabled drivers. This standard does not apply to systems and their components that have been released for production or that were developed prior to the publication date of this standard. When further development or changes are made to the system and its components that have been released for production before the release of this standard, only the modified part needs to be developed in accordance with this standard. This standard addresses the possible hazards caused by the faulty behavior of electrical and electronic safety-related systems, including the possible hazards caused by the interaction of these systems. This standard does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, energy release, etc. and similar hazards, unless the hazard is directly caused by a failure of an electrical and electronic safety-related system caused by behavior. This standard does not address the nominal performance of electrical and electronic systems, even if these systems (such as active and passive safety systems, braking systems, adaptive cruise systems) have dedicated functional performance standards. In the event of inconsistencies between this part and other parts of this standard, the requirements, recommendations and information defined in other parts of this standard shall prevail.
