UK Ministry of Defence Standard 91-91 lists simulated distillation (Simdis) method IP 406 for determining distillation properties for turbine fuel, aviation kerosene Jet A-1
In February 2005, the Ministry of Defence in the United Kingdom issued the new Defence Standard 91-91 - the requirements for one grade of kerosene type aviation turbine fuel.
Nato specifies the Defence Standard as Nato code F-35 in use for aircraft gas turbine engine fuels.
A new test requirement specifies simulated distillation (Simdis) method IP 406 as alternative to physical distillation method IP 123/ASTM D 86 for determining distillation properties.
AC Analytical Controls offers the Simdis IP 406/ASTM D 2887 application to determine the true boiling point (TBP) distribution for jet fuel and diesel.
The AC Simdis application reports both TBP and correlated IP 123/D 86 data.
The correlation for IP 123/D 86 is described in Annex G of IP 406.
In the United States ASTM method D 1655-03 lists the jet fuel specifications.
ASTM D 1655 specifies Simdis D 2887 as alternative to physical distillation method D 86 in determining distillation properties for Jet A and Jet A-1.
ASTM D 2887 is similar to IP 406.
A performance test of 120 AC Simdis units demonstrates the excellent reproducibility of the AC system compared to the ASTM D 2887 method.
Dedicated AC application software controls the Simdis application and automates all aspects of calibration, validation, sample analysis and data reporting.
Combining the automatic liquid sampler with the AC application software allows unattended, around-the-clock analyses.
AC offers a full range of samples to either calibrate or validate the application.
The samples include a calibration sample, a reference oil and two quality control samples: naphtha and jet fuel.
