Compressor inspections

An informal inspection book (collection of all
documents related to the vessel including in-
spection documents from the "approved test
centre") must be compiled for the com-
pressed air vessel on this compressor. The
vessel must be registered at an "approved
test centre" and this documentation made
available. The centre initiates and certifies
installation checks performed by authorised
experts and specifies the intervals for repeat
inspections. We recommend an inspection
interval of 5 years.
The papers accompanying the vessel are
approval documents and must be kept
throughout the service life of the vessel.
These specifications only apply in Germa-
ny. Equivalent regulations apply in other
countries.
