Defstan 9191
specifies Parker ACM20

Energy Institute test method IP 564
Parker Hannifin’s Condition Monitoring Centre, Thetford, UK, the world’s leading manufacturer and supplier of portable particle counters is at the forefront of contamination monitoring in today’s modern Aviation Turbine Fuels.

Development work carried out by the CMC engineers, in conjunction with ExxonMobil Aviation, highlighted the need for a less subjective test method than visual assessment to determine the levels of dispersed particulate contamination in Jet fuel. The existing quantitative test – Gravimetric Millipore – has poor repeatability and reproducibility and provides no information on the nature of the particulate in terms of size distribution.

5 years of field testing and development of the already established and successful LCM20 Hydraulic Laser Particle Counter saw the introduction of the Parker ACM20, with enhanced software providing the user with a better understanding of the contamination present in a sample.

As the benchmark particle counter for use in measuring the levels of contamination in fuels, the ACM20, as per the UK’s Energy Institute test method IP 564, has now been included in the DEFSTAN 9191 Jet Fuel Specification as a report only test alongside the current Gravimetric test method (IP423 or ASTM D5452) and Clear & Bright Visual test method (IP216 or ASTM D2276).

In addition to the ACM20 and sampling pump for use in the lab, Parker CMC also offers the worlds only ATEX approved portable particle counter for use in liquids, the ACM20-Z2.

To complete the family, Parker also offers the compact, in-line particle detector, the ICOUNTPD.

Parker Hannifin have been manufacturing Particle Counting equipment for 20 years and supply the worlds leading companies and militaries with contamination monitoring equipment.
