ASTM D156 Saybolt Chromometer
The height of a column of sample is decreased by levels corresponding to color numbers until the color of the sample is unmistakably lighter than that of the standard. The color number above this level is reported, regardless of whether the sample was darker, questionable, or a match at the higher level

ASTM D1322 Smoke Point Of Kerosine And Aviation Turbine Fuel
The smoke point is related to the hydrocarbon type composition of such fuels. Generally the more aromatic the fuel the smokier the flame. A high smoke point indicates a fuel of low smoke producing tendency.

ASTM D524 Ramsbottom Carbon Residue Of Petroleum Products
The carbon residue value of burner fuel serves as a rough approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. Similarly, provided alkyl nitrates are absent (or if present, provided the test is performed on the base fuel without additive) the carbon residue of diesel fuel correlates approximately with combustion chamber deposits.

ASTM D482 Ash Content Oven
Knowledge of the amount of ash-forming material present in a product can provide information as to whether or not the product is suitable for use in a given application. Ash can result from oil or water-soluble metallic compounds or from extraneous solids such as dirt and rust

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
