Hose Assemblies
Inspection
Hose assemblies must be inspected at least once a year by a competent person. A
hose assembly on which one or several of the following criteria are found must be
replaced with a new one:
Damage in the outer layer down to the core of the hose (e.g. abrasions, cuts or fis-
sures).
The outer layer of the hose is brittle (cracks in the tubing).
The hose does no longer comply with its natural shape, both with and without pres-
sure and while it is bent (e.g. layers separating, bubbles forming).
Leaks.
Damage or deformation of hose end fittings (tightness impaired); minor damage to
the surface does not require replacement.
Hose slips out of end fitting.
Corrosion on the end fitting, impairing the function and stability.
The hose is not assembled in compliance with instructions.
The storage and service life is exceeded.
Storage and service life
Hoses and hose assemblies are to be stored in a cool and dry place free of dust.
Direct exposure to sunshine or UV-rays should be avoided.

Re-use
Generally, hoses that have been in service as part of a hose assembly ought not to be
re-used in a new hose assembly, since they do no longer meet the requirements.
