The objective of the safety validation is to validate, through inspection and testing

that all safety functions are in operation as specified.

Specific validation procedures shall be developed for the actual plant; this chapter

contains some items to consider when developing the procedures.

Verify that all safety functions are tested and in operation.

Verify that tests are done to demonstrate correct system behavior upon loss of

utilities like electrical power, air or hydraulics.

Verify that tests are done to demonstrate correct system behavior upon fault of

redundant parts.

Verify that tests are done to demonstrate correct system behavior upon loss of

communications.

Verify that a correct backup of all software exists and are stored securely.

Verify that all relevant documentation is updated and stored securely.

The validation should include the following items to ensure that all temporary

degradations of the safety functions are removed:

• Verify that all applications are marked with the correct SIL mark

• Verify that no warnings are presented during compilation and download

• Verify that all forces and bypasses in the application software are removed

• Verify that all temporary bypasses and overrides in the hardware, including

field loops are removed.

• Verify that all system components (including redundant parts) are running

without any error LEDs, or error messages.

• Verify that all temporary filtering of “system alarms from hardware units” are

removed, (setting on object level in the hardware editor).
