12.15.3 Inspection criteria for hydraulic hose lines
For your own safety, comply with the following inspection criteria!
Replace hydraulic hose lines when finding any of the following
inspection criteria during the inspection:

Damage to the outer layer up to the ply (e.g. scouring points,
cuts, cracks).

Brittleness of the outer layer (crack formation of the hose materi-
al).

Deformations which do not match the natural shape of the hose.
Both in a depressurized and pressurised state or when bent (e.g.
layer separation, bubble formation, pinching, bends).

Leak points.

Damage or deformation of the hose assembly (sealing function
restricted); minor surface damage is not a reason for replace-
ment.

Movement of the hose out of the valve chest.

Corrosion of valve chest, reducing the function and strength
rating.

Installation requirements not complied with.

Life span of 6 years has been exceeded.
The date of manufacture of the hydraulic hose line on the valve
chest plus six years is decisive. If the date of manufacture on the
assembly is "2015", then the hose should not be used after Feb-
ruary 2021. For more information, see "Identification of hydraulic
hose lines".
