Important and significant changes have been included in the latest revision of DefStan Issue 6 with the introduction of a new laser based particle count test for aviation fuels IP The latest Defstan revision which was has just been published states: "The implementation date for particle counting is 30 June , but where possible, to help the data collection process, the results should be reported before that date.
Inclusion of the new laser particle test is a result of the aviation industry's ongoing efforts to enhance fuel quality and safety, increase engine reliability and reduce maintenance costs. The inclusion of IP in Revision 6 provides fuel suppliers and engine manufacturers with a more objective, quantitative assessment of the cleanliness of aviation fuel than has previously been practical.
On its journey from refinery to wing tip, aviation fuel is exposed to many sources of potential contamination with particulate matter and water causing the most common problems. IP - Determination of the level of cleanliness of aviation turbine fuels - portable automatic particle counter method. AvCount is an easy to use, rugged and portable instrument specifically designed for testing the particulate content of fuel and lubricants including all aviation turbine and gasoline fuels.
It incorporates the latest innovative measuring technology to provide a rapid test result and a very low-maintenance test instrument. The new instrument is designed for use in the laboratory or at relevant fuel distribution locations ie: airport. The measurement sequence runs automatically, with a complete test sequence in under four minutes, using only 80ml of sample.
Test results saved to memory can trend sample results, or can be downloaded to a PC for further detailed analysis using statistical quality control SQC for quality traceability. The introduction of 'Avcount' now allows fuel suppliers to provide customers with a more comprehensive and reliable 'fuel cleanliness' report while significantly reducing the effort needed for testing.
Maintenance personnel can more easily identify and isolate any potential problem in fuel filter and fuel tank systems, supporting reduced maintenance costs and downtime. In fact all those associated with the quality and cleanliness of aviation fuel can now benefit from a far superior means of ensuring fast and precise particulate analysis.

Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More D The objective is to minimize these contaminants to avoid filter plugging and other operational problems. Although tolerable levels of particulate contaminants have not yet been established for all points in fuel distribution systems, the total contaminant measurement is normally of most interest.
