IEC 61508:2010 - Functional Safety of E/E/PE Safety-related Systems 2-7.7.2: Part 2, 7.7.2 E/E/PE validation: requirements

Validation follows the prepared plan. Test and measurement equipment is calibrated with traceability to a national standard where there is one, or a recognised procedure, and checked for correct operation. Each safety function in the system safety requirements and design requirements, and all operation and maintenance procedures, are validated by test and/or analysis; where independence or decoupling between elements or subsystems cannot be shown analytically, the combined behaviours are tested. Records state per safety function the validation plan version, the function under test with its reference to the planned requirement, tools and equipment with calibration data, each result and discrepancies; where results exceed stated tolerances, the analysis and the decision to continue or raise a change request are recorded. Validation results go to the developer of the EUC together with its control system for overall validation, and Table B.5 techniques are used.

What else in your programme already covers this

This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
