This document provides a set of standard verification tasks for processor-based equipment used in safety critical applications on rail and transit systems. The standard focuses on processes that (1) define a necessary and sufficient set of analyses at the conceptual, functional, and implementation levels that comprehensively identify and verify all functions required to be implemented as fail-safe; (2) verify the level of safety achieved in the implementation of safety critical functions; and (3) define responsibilities for equipment suppliers and end users. The standard does not address quality assurance or validation processes which also affect the level of overall system safety achieved.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.

IEEE Standard for Verification of Vital Functions in Processor-Based Systems Used in Rail Transit Control
A set of standard verification tasks for processor-based equipment used in safety-critical applications on rail and transit systems is covered. This standard also covers processes that verify the level of safety achieved in the implementation of safety-critical functions that are required to be fail-safe. Quality assurance or validation processes that affect the overall level of system safety are not covered.
