Recurring test
Since hose lines are subject to influences that cause damage during operation and can lead
to dangerous situations, they must be tested recurrently at fixed intervals. The aim of recurring
tests is to detect and repair damage in good time.
The objective is to ensure that the system remains in a safe condition.
Procedure for hose lines found to be "defective"
If defects are found during the testing of the hose line that impair the safe condition of the work
equipment, these must be rectified immediately. If this is not possible, suitable measures must be
taken to ensure that the machine cannot be used further before it is repaired. Defective hose lines
must be replaced before the machine can be used further.
It is not permitted to repair or reassemble damaged hose lines with old, previously used parts!
If several hose lines are replaced at the same time, precautions must be taken to prevent mix-ups of the
connections or the installation points.
Test intervals
Deadlines for the recurring tests of the hose lines should already be set before commissioning.
Otherwise, there is a risk that work equipment will continue to be used or operated for too long without
being tested.
The intervals between the recurring tests must be selected in such a way that deviations from
the safe operating condition of work equipment can be detected and eliminated in good
time.
The intervals for recurring tests specified here are guidelines and based on experience. Shorter test
intervals may have to be specified on the basis of the risk assessment; special operating conditions; or
according to the manufacturer's specific instructions in the machine operating manual. Longer test
intervals may also be specified, provided that this is justifiable and tenable from a safety point of view.
The determination of the test intervals should be documented.
Type of test Recommended test intervals
Visual inspection Before commissioning the system
