Contamination basics
Solid contaminants in uid systems vary in size, shape
and quantity. The most damaging contaminants in fuel
systems are normally between 6 and 14 microns (and
therefore invisible to the naked eye).
The table below gives an indication of the relative sizes of
common objects.
Object Typical Size
Grain of table salt 100µm
Diameter of human hair 70µm
Limit of human visibility (naked eye) 40µm
Milled our 25µm
Red blood cells 8µm
Bacteria 2µm
NOTE: One micron (μm) equals one thousandth
of a millimetre (1μm = 0.001mm).
The ISO code
The ISO4406 code is the preferred method of reporting
quantity of contaminants in a uid. It is comprised of three
numbers i.e. XX / YY / ZZ, where:
XX is the scale number for particles larger than 4µm(c)
per millilitre of uid
YY is the scale number for particles larger than 6µm(c)
per millilitre of uid
ZZ is the scale number for particles larger than
14µm(c) per millilitre of uid
By denition the three scale numbers will always
decrease, i.e. XX > YY > ZZ.
The following table is extracted from ISO4406:1999 and
denes the range of particles that each scale number
represents.
For example code 20/18/13 indicates that:
 There are between 5,000 and 10,000 particles per
millilitre larger than 4µm(c) (i.e. scale number 20).
 Between 1,300 and 2,500 particles per millilitre larger
than 6µm(c) (i.e. scale number 18).
 Between 40 and 80 particles per millilitre larger than
14µm(c) (i.e. scale number 13).
Fuel cleanliness and contamination
Each increment of scale number represents an
approximate doubling in the quantity of particles in a
uid. In practical tests, results obtained can ick between
one scale number and the next if the actual number
of particles counted is close to the crossover point.
Conversely, results that are one scale number different
could also indicate nearly four times difference in dirt
levels (if the actual particle count on one result is close to
the lower limit of one scale number, and the other result is
close to the upper limit of the next scale number).

Preparation and guidelines for testing
Sampling methods
The icountACM202024 is capable of sampling uid in two ways:
1. Online indirect. This refers to sampling directly from a body of uid in the system at
atmospheric pressure (e.g. a tank). The system may be running or not.
2. Offline. This refers to the method of taking a sample in a sample bottle and then performing
a test either immediately or at some time later from the sample bottle.
It is important to be aware of differences that can arise from these two sampling methods
General guidelines
The following guidelines summarise best practice in order to guarantee accurate, repeatable results,
and should be adhered to for all uid sampling using the icountACM202024.
 Handle the icountACM202024 with care; it is a precise instrumentation product.
 Ensure hoses and sampling pipes are tted and where applicable tightened correctly.
 Replace the sampling pipes regularly.
 Cap the ends of sampling pipes after use to prevent dirt ingress.
 When sampling from fuel tanks keep the pipe inlet away from the sides or bottom of the tank
to ensure you are sampling the main body of the fuel.
 Discard all waste uid – do not recycle any uid once it has been through the
icountACM202024
 Use consistent sampling methods
 For trend monitoring, ensure samples are taken under similar working conditions
 Re-calibrate the unit annually.
CAUTION!
Only turn the valve when starting a test and only when the valve turn symbol ( or ) is
shown on the display, or % by volume, or ISO4406 (all channels) screens are displayed.
3m of inlet sample pipe is provided. This should be cut down to the minimum convenient length for
sampling (this will prolong battery life and reduce the risk of dirt build-up along the length of pipe).

INTRODUCTION
Parker Hannifin icountACM202024 15
g
Specific guidelines for Method 1 (Online indirect)
When sampling using method 1 it is better if the system is running as this will agitate the uid. If the
uid is static, sample results may depend on the exact position of the inlet pipe, due to settling.
In some cases this may not be possible, and so consistent methods should be used.
Specific guidelines for Method 2 (Offline)
For full details of the preferred testing method, please refer to the UK’s Energy Institute (EI) test
method IP564 (‘IP 564 Determination of the level of cleanliness of aviation turbine fuel — Laboratory
automatic particle counter method’, available from www.energyinstpubs.org.uk).
CLEANING SAMPLE BOTTLES
Bottles used for sampling must be cleaned prior to use. This is best done using the uid to be
sampled, as follows:
1. Fill the bottle a half to two-thirds with uid.
2. Screw the cap on and then shake vigorously for 30 seconds.
3. Uncap and drain the bottle.
4. Repeat steps 1 to 3 two further times (i.e. a total of three times).
5. The sample bottle is now ready for use.
PRIOR TO TESTING
Prior to any testing of any bottled uid (including verication uid), the uid should be gently agitated
to ensure a good mix. This is best done by slowly tumbling the bottle end over end at a tilted angle
for about 60 seconds, as shown below.
DO NOT SHAKE the fluid sample at this stage as this will introduce air in the uid and lead to poor
results. A gentle tumbling action is required.

Operation
Once the icountACM202024 has been set up, it is ready to check uid cleanliness levels.
NOTE: The icountACM202024 contains aviation fuel and may need to be flushed prior to
use.
Connecting sampling hoses
Connect the sample hoses to the ‘INLET’ and ‘OUTLET’ connections. These are push-t
connections.
To remove the blanking plugs (or the hoses) from the tting, push both the plug/hose and the outer
ring (arrowed) towards the tting. Then, while keeping the ring pushed in, gently pull the plug/hose
to withdraw.
To t a hose or plug, push into the tting until the seal resistance is overcome.
Priming the transfer pump
To avoid large volumes of air passing through the ACM unit, which can give incorrect readings, the
transfer pump should be primed before use. To do this, disconnect the hoses to the main unit from
P1/P2 on the transfer pump unit and connect the link hose in their place. Put the inlet hose into the
uid and run the pump until uid comes out of the outlet hose.
NOTE: When connecting P1 and P2, take care to align the central tube with the fitting and
only screw on finger-tight.
NOTE: Press and hold down the ‘FLUSH’ button to speed up the pump. (The FLUSH
button should only be used during priming/flushing and not during a test).
Once the pump and tubing are primed with the test uid the hoses from the ACM can be
reconnected. It is then recommended to run a minimum of four tests, discarding the rst test result,
as this may be a mixed result with previous uid from the ACM.
