Bottle Cleanliness
It is preferable that bottles have sealing screw caps
and both parts are cleaned to a suitable level in
accordance with ISO3722.
Standard Parker bottles are supplied clean to
ISO15/13/10 (NAS Class 4).
The bottle should remain capped until time of sample
filling and re-capped immediately afterwards.
Sample Mixing
Sedimentation of contaminant in a sample will occur,
the rate of which is dependent upon both fluid and
particle characteristics.
Samples should be analysed, without delay, once
agitated and de-gassed.
System Flow Rate
Samples are best taken from a point in the system
where the flow is TURBULENT (Reynolds No. greater
than 4000). The turbulent flow creates a mixing
action. Where flow is streamline or LAMINAR, larger
particulate may tend to settle toward the lower pipe
surface and not be sampled.
System Condition Changes
Changes in the system operating condition, flow,
temperature, pressure or vibration, can result in
previously sedimented contaminant being retrained
into the flowing oil. It is also possible that these
changes may cause partially contaminated filter
elements to shed particulate into the system. Samples
should, therefore, be extracted when the system is in
a steady state condition and the result less likely to
be distorted by contaminant peaks.
There are a number of proprietary sampling valves
available which adhere to good theoretical principles.
However, they do tend to generate a level of precision
and cost which is unnecessary for trend monitoring.
Sampling points should enable extraction of a sample
without changing the system’s condition. Fine control
needle valves are not desirable, as they have a
tendency to silt up under some operating conditions,
causing the distribution of contaminants in the fluid to
be changed. The sampling port should be protected
to maintain cleanliness and thoroughly flushed before
collecting the sample for analysis. Allow sufficient
airspace in the bottle to enable 80% fill.
