ASTM D2624 Conductivity Of Aviation Fuel
The ability of a fuel to dissipate charge that has been generated during pumping and filtering operations is controlled by its electrical conductivity, which depends upon its content of ion species. If the conductivity is sufficiently high, charges dissipate fast enough to prevent their accumulation and dangerously high potentials in a receiving tank are avoided

EN14538 Ca, K，Mg And Na Content In FAME
Biodiesel, defined as a mixture of mono-alkyl esters, is produced from a wide range of vegetable oils and animal fats more commonly by a lipid transesterification process [1-3]. Biodiesel can be substituted for petroleum-based diesel fuel (petrodiesel) in virtually any standard unmodified diesel engine [4, 5]. Pure biodiesel or biodiesel blended with petroleum diesel can be used to fuel diesel vehicles, providing energy security and emissions and safety benefits

ASTM D2276 Particulate Contaminant In Aviation Fuel By Line Sampling
This tester provides a gravimetric measurement of the particulate matter present in a sample of aviation turbine fuel by line sampling. 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

ASTM D4052 Digital Density Meter
U-tube oscillating density meter, electronic liquid density meter is based on the principle of different oscillating frequency when the double U-tube is filled with different media. After pumping the sample into the resonance tube sensor, the measurement data is processed by the single chip microcomputer, it features fast , direct, and has high sensitivity. It consists of a dual tuning fork density sensor, vibrating tube circuit, temperature measuring circuit, CPU, display, constant temperature
