Verification and validation

Contents of this chapter

This chapter describes verification and validation of the implemented safety
functionality.
Verification and validation produce documented proof of the compliance of the
implementation with specified safety requirements.
Further information can be found in Technical guide No. 10 - Functional safety
(3AUA0000048753 [English]).

Verifying the achieved SIL/PL level

Verification of the functional safety system demonstrates and ensures that the
implemented safety system meets the requirements specified for the system in the
safety requirements specification phase.
The most convenient way to verify the required SIL/PL level reached with the
implemented system is to use a specific safety calculator software.

Validation procedure

It is always the responsibility of the machine builder to ensure that the functionality of
all the required safety functions has been appropriately verified and validated.
WARNING! Until all the safety functionality is validated, the system must not
be considered safe.
The acceptance test must be performed to each safety function.
