Fuel Testing

microbial detection

How important is it to test your fuel? If you have emergency backup power generators, then regular testing is imperative. Where to start? Proper sampling is the first place to start. Taking a good bottom sample will determine visual cleanliness but not necessarily ideal cleanliness. At best, the human eye can see objects as small as 40 microns. A human hair measures around 80 microns across and a microbe can be as small as 2 microns. The injector design of diesel engines requires clearances as close as 2 microns, so microbial contamination too small to see with the naked eye may be causing untold damage to the engine.

What determines clean fuel? The ISO Cleanliness Code standard is 18/16/13. What does this mean? It represents the allowable range of particles found at the particle sizes 4, 6 and 14 microns. Refer to the chart and you will see that at 4 microns and larger, there can be 1,300-2,500 particles per milliliter of diesel. At 6 microns or large only 320-640 particles and at 14 microns 40-80 particles. Remember these are all microscopic in size. If you have enough the fuel will likely be cloudy and discolored. Entrained water can also count as a particle.iso

The key to having clean fuel is the implementation of a fuel quality management program that samples, tests and cleans on a regular basis. Clean fuel does not just happen and it is likely that the new fuel just delivered will not meet the ISO Cleanliness standard of 18/16/13.
