The experience of designers and users of hydraulic and lubrication
systems is that 75% of system failures are as a direct result
of contamination. Knowing the cleanliness level of the fluid is the
basis for contamination control.

with ISO Medium Test Dust (MTD) based on
ISO 11171:1999 calibration standard.
The new MTD has a certified distribution standard
verified by NIST (National Institute of Standard
and Technology), USA. The LPA2 is designed to meet
the new ISO 4406 cleanliness classification code which
is a 3-part code, 4µm(c), 6µm (c) and 14µm(c).
The LPA2 also provides results in the NAS 1638 code.

bottle sampler
A simple selection of the
correct switch will enable the
user to choose between Vacuum
for de-aeration or Sample to carry
out analysis of the bottle sample.
A highly aerated fluid may lead to inaccurate result when
analysed, therefore a de-aeration facility has been
incorporated into the bottle sampling units. By evacuating
the sampling chamber aeration within the fluid is removed
and the fluid is conditioned prior to sampling
Any entrained or free air in the oil media at time of bottle
Sampling may be shown as part of the particle count.
This would lead to inaccuracies of the cleanliness results.
As air can be seen as a contaminant.
An example of the difference between an aerated sample
and a non aerated sample can be seen in this picture.
It is essential that only sample bottles which have been
cleaned to ISO 3722 standard are used. Modern hydraulic
systems featuring highly effective filters have fluid cleanliness levels that approach that of the sample bottle itself.
The use of un-cleaned bottle can greatly increase
the particle counts. ( Please note sterilisation kills bacteria
but does not remove particles). Perhaps of even greater
concern is the variability in their levels of cleanliness.
A sudden increase in contamination could be caused by
the sample bottle. This apparent increase could instigate
unnecessary corrective action.

Sample bottles.

standard sample bottles. Par t No: .P. O2.
These have been cleaned in
accordance with DIN/ISO 5884.

The PML2-W provides accurate and repeatable measurement
of the % saturation of water. RH (relative humidity)
Different oils have different saturation levels and % saturation
is the best and most practical measurement.
These results can be converted to PPM (parts per million),
if the oil type saturation/temperature characteristic is known.
Measuring water in hydraulic
and lubricating fluids
(from Nor th Notts Fluid Power Centre)
WATER CONTENT
In mineral oils and non aqueous fire resistant fluids water is undesirable.
Mineral oil usually has a water content of 50-300 ppm which it can suppor t
without adverse consequences.
Once the water content exceeds about 500ppm the oil star ts to appear hazy.
Above this level there is a danger of free water accumulating in the system
in areas of low flow. This can lead to corrosion and accelerated wear.
Similarly, fire resistant fluids have a natural water content which may be
different to mineral oil.

System contamination monitoring is achieved by using an in-line
particle counter (PML2) on each service module.
A “Modbus” protocol enables the PML2 to be programmed
to communicate with a Programmable Logic Controller. (PLC).
This measures and reports the cleanliness of the various
aircraft hydraulic systems.
