1.2 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 com-
missioning nor their periodic testing by a qualified person (see chapter 2.2 "Necessary compe-
tencies"). The checklists contain minimum testing requirements. Depending on the application,
other tests may be necessary.
