The purpose of this safety verification process standard is to provide a well-defined and well-structured set of analysis methods and documentation which: fulfills the primary purpose of the verification process, is flexible enough to accommodate all viable design methods, and satisfies the safety requirements of the end user. This standard (1) defines a necessary and sufficient set of analyses at the conceptual, functional, and implementation levels which comprehensively identify and verify all functions required to be implemented as fail-safe (2) defines responsibilities for equipment suppliers and end users.
