1.4 Checklists
The checklists serve as a reference for the machine manufacturer or supplier (see chapter 12 "Testing").
They replace neither testing of the complete machine or system prior to the initial start-up nor their periodic
testing by a competent person. The checklists contain minimum testing requirements. Depending on the
application, other tests may be necessary.
