The qualified person inspecting the HB system is responsible for the type and scope of the inspection.

In addition to the points described here, all points outlined in the other supplied product manuals must also be checked.

The decision as to whether the HB system is in a perfect condition may only be made by the examiner. Any inadequacies, if found, must be eliminated. The examiner decides whether the HB system will then need to be inspected again.

If locally applicable regulations specify further tests, these are likewise to be carried out.
