5.1.2 Procedure for In-Loop Proof Test
If you check the safety function within an application, 90 % of the dangerous undetected
failures are revealed.
You can also use documented switching actions for verification within the framework of regular
proof test intervals. The calculated values correspond to the values in the
"Characteristic Safety Values" table, see chapter 3.4
