Four Ball Wear Tester
This test method, used for specification purposes, differentiates between lubricating fluids having low, medium, and high level of extreme-pressure properties. The user of this method should determine to his own satisfaction whether results of this test procedure correlate with field performance or other bench test machines.

ASTM D5708 ICP for Crude Oils and Residual Fuels
When fuels are combusted, vanadium present in the fuel can form corrosive compounds. The value of crude oils can be determined, in part, by the concentrations of nickel, vanadium, and iron. Nickel and vanadium, present at trace levels in petroleum fractions, can deactivate catalysts during processing. These test methods provide a means of determining the concentrations of nickel, vanadium, and iron.

ASTM D2163 Hydrocarbons In LPG By GC
The hydrocarbon component distribution of liquefied petroleum gases and propene mixtures is often required for end-use sale of this material. Applications such as chemical feed stocks or fuel require precise compositional data to ensure uniform quality. Trace amounts of some hydrocarbon impurities in these materials can have adverse effects on their use and processing.

ASTM D7111 ICP for Middle Distillate Fuels
Trace elemental analysis is used to indicate the level of contamination of middle distillate fuels. Trace metals in turbine fuels can cause corrosion and deposition on turbine components at elevated temperatures. Some diesel fuels have specification limit requirements for trace metals to guard against engine deposits. Trace level copper in middle distillate aviation turbine fuel can significantly accelerate thermal instability of the fuel leading to oxidation and production of detrimental insoluble deposits in the engine.

ASTM E659 Autoignition Temperature Tester
KN-659 Autoignition Temperature Tester conforms to ASTM E659 Standard Test Method for Autoignition Temperature of Chemicals. A small, metered sample of the product to be tested is inserted into a uniformly heated 500ml glass flask containing air at a predetermined temperature. The contents of the flask are observe in a dark room for 10min following insertion of the sample, or until autoignition occurs. Autoignition is evidenced by the sudden appearance of a flame inside the flask and by a sharp rise in the temperature of the gas mixture. The lowest internal flask temperature at which hot-flame ignition occurs for a series of prescribed sample volumes is taken to be the hot-flame autoignition temperature of the chemical in air at atmospheric pressure. Ignition delay times (ignition time lags) are measured in order to determine the ignition delay-ignition temperature relationship.

ASTM D8288 Automatic Tapping Torque Testing System
KN-8288 Automatic Tapping Torque Testing System conforms to ASTM D8288 Standard Test Method for Comparison of Metal working Fluids Using a Tapping Torque Test Machine. This test method can be used to predict the comparative lubricating properties of a metalworking fluid (MWF). Fluids that produce lower torques or higher efficiencies are predicted to have better machining characteristics. The method is applicable to all tap types, machining speeds, alloys and coatings that can be fabricated into a test piece. Comparison between different operating conditions or various types of fluids can be made. The reportable quantity is the efficiency or mean average torque of a reference fluid divided by the mean average torque of the fluid of interest.
