Testing hose lines
An essential factor in ensuring operational safety when handling L&W compressors is the proper testing
of the hose lines used.
Tests are necessary:
After assembly and before commissioning the hose line.
After accidents, changes (modifications) to the compressor system, longer periods of non-
use and damage due to, for example, collisions or natural phenomena (extraordinary test).
After carrying out repair work on the compressor system that could compromise safety.
Recurrently at fixed, regular intervals.
The proprietor must determine the type, scope and deadlines for the tests according to his or her
individual operating conditions and on the basis of a risk assessment.
The specifications and
recommendations of the manufacturer must be observed.
The specifications made regarding type,
scope and deadlines (as well as the replacement intervals) must be documented in writing as
occupational health and safety measures.
The results of the tests must also be recorded, e.g. together with the test report of the machine,
and kept at least until the next test.
The above-mentioned tests may only be carried out by persons who are qualified to do so and who are
authorized by the company (employer).
Testing after assembly and before commissioning
In the test after assembly and before commissioning, factors relating to assembly or factors that
can only be evaluated on the fully assembled machine must be assessed.
The assembled hose lines must also be assessed.
Some test points can already be assessed during a visual inspection when the machine is switched off.
An overview of the recommended scope of testing for a visual inspection of hose lines is given in the
appendix.
Further test points included in the test of hose lines before commissioning, require a functional test with
the machine running.
A recommendation for the scope of testing is given in the appendix.
