While the performance of a particular equipment piece or system can depend upon numerous factors, the quality of fuel present within an apparatus can also have a major effect. In order to determine whether or not present fuel is good for a particular application, it is useful to have an understanding of fuel quality testing and how it is carried out.
If available, some organizations and countries have established facilities for high-level distributors to have samples comprehensively tested for quality. During these procedures, fuel will often undergo distillation, titration, X-ray fluorescence testing, and much more. For the end user themselves, fuel testing will typically center around periodic checks, those of which determine whether water, inorganic substances, or bacteria has contaminated a sample. These contaminants can typically be found with fuel testing equipment, and it is important to be aware of potential contamination which can arise from worn-out equipment pieces or long term storage of fuel.
When conducting fuel testing by oneself, there are a few ways in which substances such as water and bacteria may be detected. Water is by far the most common source of contamination in fuel, and water sensors may be employed for determining whether or not a sample is at risk. Generally, these sensors will feature a probe that is inserted into the fuel, and an electric current is induced. Constructed of stainless steel and NPT brass threading, the sensor utilizes an indicator to convey whether or not moisture is present. Most often, the sensor light will only illuminate if there is water. To ensure the safety of such components with their use of electrical currents, water sensors have their probe grounded.
For finding potential organic materials within a sample of fuel, fuel testing equipment known as dip slide fuel tests may be relied on. These are the most optimal tools to use, capable of detecting fungi, bacteria, and any present mold within fuel. Each test slide is stored in a separate tube, and all slides have a white side for bacteria detection and an off-white side for mold detection. When conducting a test, the slide should be dipped into a fuel filter sample for around 15 seconds. Then, any excess fuel should be shaken off before the sample is put back into the tube. Once stored in a dark room, checks should be made at the 24, 36, and 48 hour marks. Generally, bacteria will begin to show itself between 24-36 hours of sitting, while mold will appear between 36-48 hours.
Fuel contamination can occur from a variety of reasons, even if fuel is thought to be properly stored. As contaminated fuel may affect the general performance of various machinery and may even threaten overall health, it is crucial that fuel testing is regularly carried out on recommended intervals.
