SIA «SNE Serviss»

Since 02 January, 2014 the Repair and Diagnostics Centre SNE Serviss provides field RAPID ANALYSIS OF FUEL by means of the special equipment «Hartridge FQM-20» serial number CG.84024.L (Fuel Quality monitor).

The equipment have passed the certification and calibration following the Standard ISO11171, and it is ready to perform the fuel analysis according the standard ISO 4406:1999, (the test is carried out according the standard ISO 4406:1999).

ISO 4406:99 Cleanliness level Standards.

Range number	Number of particles per fuel milliliter
24	from 80 000	to 160 000
23	from 40 000	to 80 000
22	from 20 000	to 40 000
21	from 10 000	to 20 000
20	from 5 000	to 10 000
19	from 2 500	to 5 000
18	from 1 300	to 2 500
17	from 640	to 1 300
16	from 320	to 640
15	from 160	to 320
14	from 80	to 160
13	from 40	to 80
12	from 20	to 40
11	from 10	to 20
10	from 5	to 10
9	from 2.50	to 5
8	from 1.30	to 2.50
7	from 0.64	to 1.30
6	from 0.32	to 0.64

For the analysis the fuel can be taken «From Car Tank Filtration» and «On Board Filtration». According the Standard ISO 4406:1999 contamination level of fuel in the fuel tank must be not higher than 18/16/13, but after the fine filter - 12/9/5.

The table below shows the permissible quantity of fuel contamination recommended by the engine manufacturer CUMMINS.

Definition of particles ISO 4406 / Cummins.

Fuel status	ISO 4406	Particle counts per ml Fluid Sample	Comments
Fuel supply. Unacceptable	22 20 18	up to 40 000 > 4μm up to 10 000 > 6μm up to 2 500 > 14μm	Typical levels of incoming fuel (Primary source of fuel contamination)
Tank filtration	18 16 13	up to 2 500 > 4μm up to 2 500 > 6μm up to 80 > 14μm	Maximum recommended by engine manufacturer (Secondary leading source of contamination)
On board filtration	15 13 10	up to 320 > 4μm up to 80 > 6μm up to 10 > 14μm	Preferred by engine manufacturer
High pressure CR. Acceptable	12 9 6	up to 40 > 4μm up to 5 > 6μm up to 0.64 > 14μm	Preferred by fuel injector manufacturer

Rapid analysis of fuel gives us possibility to specify the contamination level, presence of water, presence of small particles which is not visible by eye but which affects an engine's work and its operating life.

Leading causes for test analysis of fuel:

• quality of diesel engine for sale at filling stations;
• repair quality of fuel system;
• quality of fuel filtration, tank and on board filtration.

After analysis you can receive the print-out of results and, when necessary, the statement of fuel conformity for use in the fuel system, of which the analysis was performed.
