Achieve optimal fuel system performance through precise ISO cleanliness targets. Our guidelines ensure fuel quality compliance while minimizing contamination-related failures in heavy-duty fleets.
Advanced protocols for maintaining ISO cleanliness standards in fuel management.
ISO cleanliness targets refer to standardized codes (ISO 4406) that specify acceptable particle contamination levels in fuel and lubricants for optimal equipment performance.
These targets help fleet managers maintain diesel fuel testing standards by quantifying particle counts in three size ranges: 4μm, 6μm, and 14μm. Proper adherence prevents injector wear, filter clogging, and system failures in heavy vehicles.
| System Type | Target Code | Max Particles |
|---|---|---|
| High-Pressure Fuel | 18/16/13 | 1300/320/80 |
| Hydraulic Systems | 20/18/15 | 5000/1300/320 |
| Engine Oil | 21/19/16 | 10000/2500/640 |
| Transmission | 19/17/14 | 2500/640/160 |
| Bulk Storage | 22/20/17 | 20000/5000/1300 |
Essential protocols that ensure compliance with ISO cleanliness standards for superior fuel management
Step-by-step process to achieve and maintain ISO cleanliness standards in your fuel system
Evaluate current fuel quality, analyze contamination sources, and baseline ISO codes for your fleet.
Install appropriate filtration, implement DEF storage and quality controls, and establish handling procedures.
Educate staff on ISO standards, testing methods, and contamination prevention techniques.
Regular testing, track ISO codes, and adjust processes for continuous improvement.
Fleets maintaining strict ISO cleanliness targets report significant reductions in fuel system issues and operational costs.
Reduction in injector failures
Decrease in filter replacements
Improvement in fuel economy
Compliance success rate
"Implementing ISO cleanliness targets transformed our fuel management, reducing breakdowns by 70% and extending engine life in our heavy-duty fleet."

Get answers to the most frequently asked questions about implementing ISO cleanliness targets
The three numbers represent particle counts per ml for sizes >4μm, >6μm, and >14μm. Lower numbers indicate cleaner fluid. For example, 18/16/13 means up to 1300 particles >4μm, 320 >6μm, and 80 >14μm.
Testing frequency depends on system criticality. Critical systems like high-pressure fuel injectors should be tested monthly, while bulk storage can be quarterly. Align with your oil sampling intervals for consistency.
Implement immediate filtration, check storage systems, and perform root cause analysis. Upgrade filters or change suppliers if needed. Monitor closely until targets are met to prevent damage.
No, targets vary by system. Fuel systems require stricter codes (e.g., 18/16/13) than hydraulic systems (20/18/15). Consult OEM specifications and adjust for operating conditions.
Water promotes microbial growth and corrosion, increasing particle counts. Maintain water content below 200 ppm and use water-absorbing filters to support ISO targets.
Particle counters, sample bottles, vacuum pumps, and lab analysis kits. For in-house testing, invest in automatic particle counters calibrated to ISO standards.
