Validation of the safety functions

You must do an acceptance test (validation) to validate the correct operation of safety
functions.

Competence

The acceptance test of the safety function must be carried out by a competent person with
expertise and knowledge of the safety function as well as functional safety, as required by
IEC 61508-1 clause 6, and ATEX/Ex regulations. The test procedures and report must be
documented and signed by this person.

Validation procedure

You must do the acceptance test using the checklist given in section Start-up and acceptance
test:
• at initial start-up of the safety function
• after any changes related to the safety function (wiring, components,
safety-function-related parameter settings, etc.)
• after any maintenance work related to the safety function.
The acceptance test must include at least the following steps:
• you must have an acceptance test plan
• you must test all commissioned functions for proper operation, from each operation
