ISO 4406 determines the cleanliness of a fluid and
is used by OEMs to define sentencing limits of the
components of an injection system, engine diesel
or hydraulic system.
The ISO 4406 test is a granulometry analysis that is carried
out on the fluid and a qualification of 3 codes is obtained:
Code 1: particle content greater than 4 microns per ml
Code 2: content of particles greater than 6 microns per ml
Code 3: content of particles greater than 14 microns per ml
Depending on the type of component, OEMs define an ISO
code that determines the correct operation of the system.
GETTING THE MAXIMUM OF POWER
The dosage of the injectors is affected by particles larger than 4 microns; This leads to loss of power, high premature cylinder wear, premature compression loss, and a contaminated lubricant raising friction.
Result:
- Increased fuel consumption,
- Failures and downtime
- Decrease in oil interval
- Decreased engine life
The associations of engine manufacturers of the world issue the base document of the diesel fuel specifications, determining the maximum limit ISO 18/16/13.
The ISO Standard has been in force since Tier I engines, since 1998.
Injection systems mark the fundamental advance in improving
engines and their efficiencies; which accompanies the
evolution of ISO 4406 codes.
Unfortunately, there are those who confuse the sulfur content
as the greatest impact, but this has nothing to do with the
content of ISO particles.
Without a doubt, reducing sulfur is important, but ISO 4406
applies from the first generations of engines.
More than 4 microns:
20,000-40,000 in 1 milliliter
More than 4 microns:
1,300-2,500 in 1 milliliter
More than 4 microns:
10-20 in 1 milliliter
