In the railways field the "Safety Case Report" is very well defined. We have a normative (EN50129) devoted to define what is a "safety case". You can download this normative from https://law.resource.org/pub/bg/ibr/bds.en.50129.2003.pdf (the normative text is in English, NOT in Bulgarian). For me "safety case REGIME" is a new concept. In some ways, this standard is in fact a "law", as it is required by some national laws (you can read more on this in law.resource.org).
The following is an extract of this normative.
The Safety Case contains the documented safety evidence for the system/sub-system/equipment, and shall be structured as follows:
Part 1 Definition of System (or sub-system/equipment) This shall precisely define or reference the system/sub-system/equipment to which the Safety Case refers, including version numbers and modification status of all requirements, design and application documentation.
Part 2 Quality Management Report
This shall contain the evidence of quality management, as specified in 5.2 of this standard. Part 3 Safety Management Report
This shall contain the evidence of safety management, as specified in 5.3 of this standard. Part 4 Technical Safety Report
This shall contain the evidence of functional and technical Safety, as specified in 5.4 of this standard. Part 5 Related Safety Cases
This shall contain references to the Safety Cases of any sub-systems or equipment on which the main Safety Case depends.
It shall also demonstrate that all the safety-related application conditions specified in each of the related sub-system/equipment Safety Cases are
either fulfilled in the main Safety Case, or carried forward into the safety-related application conditions of the main Safety Case. Part 6 Conclusion
This shall summarise the evidence presented in the previous parts of the Safety Case, and argue that the relevant system/sub-system/equipment is adequately safe, subject to compliance with the specified application conditions.
The structure of the Safety Case is illustrated in Figure 3.
