General rules, notes and definitions

Validation of the safety functions

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

Validation procedure

You must do the acceptance test using the checklist given in section
acceptance test on page 18:
•
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 action 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
location
•
you must document all acceptance tests.

Acceptance test reports

You must store the signed acceptance test reports in the logbook of the machine. The
report must include, as required by the referred standards:
•
a description of the safety application (including a figure)
•
a description and revisions of safety components that are used in the safety
application
•
a list of all safety functions that are used in the safety application
•
a list of all safety related parameters and their values
•
documentation of start-up activities, references to failure reports and resolution of
failures
•
the test results for each safety function, checksums, date of the tests and confirmation
by the test personnel.
You must store any new acceptance test reports performed due to changes or
maintenance in the logbook of the machine.

Competence

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