In order to complement our research capability in keeping with the aviation fuel aviation characterisation requirements, we are looking to procure an automated Tensiometer for precise and reliable aviation fuel testing in keeping with ASTM D1331. Surface tension is a measurement of the cohesive energy present at an interface. Values for surface tension are usually given when the surface of the liquid is in contact with air. This understanding is important in two key fuel areas: • The movement of gas (air) into and out of turbine fuel • The movement of turbine fuel into airstreams by atomization The same concepts apply when the interface is between two liquids, where it is typically called interfacial tension. This is important to the movement of water into and out of turbine fuel, and is a key topic in fuel handling and cleanliness. Fluids with large cohesive forces among molecules, like those found in water, exhibit high surface tensions. Non polar fluids such as hydrocarbons have lower internal cohesive forces and lower surface tensions. Surface tension decreases toward zero as temperature increases, and cohesive forces are overcome until, at the fluid's critical temperature, surface tension becomes negligible.

In order to complement our research capability in keeping with the aviation fuel aviation characterisation requirements, we are looking to procure an : Dynamic Viscosity Measurement Device for precise and reliable testing results in keeping with ASTM D7042. This test method covers and specifies a procedure for the concurrent measurement of both the dynamic viscosity, η, and the density, ρ, of liquid petroleum products and crude oils, both transparent and opaque. The kinematic viscosity, ν, can be obtained by dividing the dynamic viscosity, η, by the density, ρ, obtained at the same test temperature. The result obtained from this test method is dependent upon the behaviour of the sample and is intended for application to liquids for which primarily the shear stress and shear rate are proportional (Newtonian flow behaviour). Viscosity decreases with increasing temperature, but the form of the functionality is not as simple as for density. Many mathematical descriptions for viscosity as a function of temperature have been proposed, and the form of that functionality differs among the models.

In order to complement our research capability in keeping with the aviation fuel aviation characterisation requirements, we are looking to procure an Simulated Distillation Unit based on Chromatography for precise and reliable testing results in keeping with ASTM D2887 and IP 406. ASTM D2887 covers the determination of the boiling range distribution of petroleum products. Simulated distillation is a GC method used to characterise petroleum fractions and products, since it permits the quick determination of their boiling range distribution. Samples are analysed on a non-polar chromatographic column that separates the hydrocarbons in order of their boiling points. These are correlated with the retention times, through a calibration curve obtained by running under the same conditions a known mixture of hydrocarbons, usually n-alkanes, covering the boiling range expected in the sample. Results are reported as a correlation between the boiling points and the percentages of the sample eluted from the column. The determination of the boiling range distribution of petroleum fractions by conventional GC is a rapid analytical tool, which is widely used to replace conventional distillation methods for control of refining operations and specification testing. The test method is applicable to petroleum products and fractions with a final boiling point of 538 °C (1000 °F) or lower at atmospheric pressure as measured by this test method. This test method is limited to samples having a boiling range greater than 55.5 °C (100 °F), and having a vapor pressure sufficiently low to permit sampling at ambient temperature.

In order to complement our research capability in keeping with the aviation fuel aviation characterisation requirements, we are looking to procure an automated test device for determining specific heat by Differential Scanning Calorimetry for precise and reliable aviation fuel testing in keeping with ASTM E1269. The specific heat of a fuel is the amount of heat-energy transferred into or out of a unit mass of the fuel when increasing or decreasing its temperature. In fuel system analysis, specific heats are used in the calculation of heat transfer, using the fuel as a coolant or as a heat sink. Specific heat is given in terms of kilojoules per kilogram. This test method covers the determination of specific heat capacity by differential scanning calorimetry. This test method is generally applicable to thermally stable solids and liquids. The normal operating range of the test is from -100 600 °C. The temperature range can be extended depending on instrumentation and sample.

In order to complement our research capability in keeping with the aviation fuel aviation characterisation requirements, we are looking to procure an Digital Density Meter for precise and reliable testing results in keeping with ASTM D4052. This test method covers the determination of the density, relative density, and API Gravity of petroleum products and viscous oils, which can be handled as liquids at the temperature of test, using either manual or automated sample injection equipment. However, what we are seeking to buy is an automated sample injection device. The application of this method is restricted to liquids with total vapor pressure below approximately 15 000 mm2/s at the temperature of test. The total vapor pressure limitation however can be extended to >100 kPa provided that it is first ascertained that no bubbles form in the U-tube, which can affect the density determination. Some examples of products that may be tested by this procedure include: gasoline and gasoline-oxygenate blends, diesel, jet, basestocks, waxes, and lubricating oils. Density is the mass per unit volume relationship of fluids. Generally, relative density is the ratio of the density of a particular liquid fuel to the density of water at 15.5°C and is commonly referred to as specific gravity. These relationships are important in the design of aircraft and missiles, since fuel density variations can have significant impact on determining loaded weight and the range attainable. They are also used in flow calculations, fuel gaging, metering device considerations, fuel loading, thermal expansion of fuels, and fuel tank design. Temperature has a marked and inverse effect on the density of fuels. As the temperature increases, the density of a fuel decreases. Relative density, or specific gravity, is dimensionless since it is a ratio of the density of a substance to the density of a reference substance, namely water. Density varies with temperature therefore the temperature of the liquid being compared to the reference substance and the temperature of the reference substance, itself, must be given. Relative density can also be expressed in terms of American Petroleum Institute (API) gravity.

In order to complement our research capability in keeping with the aviation fuel aviation characterisation requirements, we are looking to procure an automated conductivity response device for precise and reliable aviation fuel testing in agreement with ASTM D2624. These test methods cover the determination of the electrical conductivity of aviation fuels and liquid distillates with and/or without a static dissipator additive. The test methods normally give a measurement of the conductivity when the fuel is uncharged, that is, electrically at rest (known as the rest conductivity). Two test methods are available for field tests of fuel conductivity. These are: (1) portable meters for the direct measurement in tanks or the field or laboratory measurement of fuel samples, and (2) in-line meters for the continuous measurement of fuel conductivities in a fuel distribution system. In using portable meters, care must be taken in allowing the relaxation of residual electrical charges before measurement and in preventing fuel contamination.
