Checklists

The checklists (see chapter 9 "Testing") serve as a reference for the machine manufacturer or supplier.
They replace neither testing of the complete machine or system prior to initial commissioning nor their peri-
odic testing by a qualified person (see chapter 2.2 "Necessary competencies"). The checklists contain mini-
mum testing requirements. Depending on the application, other tests may be necessary.
