ASTM D2595 Lubricating Grease Wide Temperature Range Evaporation Loss Tester
KN-2595 Lubricating Grease Wide Temperature Range Evaporation Loss Tester conforms to ASTM D2595 Standard Test Method for Evaporation Loss of Lubricating Greases Over Wide-Temperature Range. A weighed sample of grease in an evaporation cell is placed in a heating device maintained at the desired test temperature. Heated air is passed over the grease surface for 22h±0.1h. The loss in weight of the sample due to evaporation is determined.

ASTM D4048 Copper Corrosion From Lubricating Grease
A prepared copper strip is totally immersed in a sample of grease and heated in an oven or liquid bath at a specified temperature for a definite period of time. Commonly used conditions are 100 6 1°C (212 6 2°F) for 24 h 6 5 min. At the end of this heating period, the strip is removed, washed, and compared with the Copper Strip Corrosion Standard.

ASTM D1384 Corrosion Test For Engine Coolants In Glassware
this test method will generally distinguish between coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation.however, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. the sctual serivice value of an engine coolant formulation can be determined only by more comprehensive bench,hynamometer,and field tests

ASTM D323 Automatic Reid Vapor Pressure Bath
Vapor pressure is an important physical property of volatile liquids. This tester is used to determine the vapor pressure at 37.8°C (100°F) of petroleum products and crude oils with initial boiling point above 0°C (32°F). Vapor pressure is critically important for both automotive and aviation gasolines, affecting starting, warm-up, and tendency to vapor lock with high operating temperatures or high altitudes. Maximum vapor pressure limits for gasoline are legally mandated in some areas as a measure of air pollution control.

ASTM D6377 Apparatus for Vapor Pressure of Crude Oil
KN-6377 Apparatus for Vapor Pressure of Crude Oil conforms to ASTM D6377 Standard Test Method for Determination of Vapor Pressure of Crude Oil: VPCRX (Expansion Method). Employing a measuring chamber with a built-in piston, a sample of known volume is drawn from the sample container into the temperature controlled chamber at 20℃ or higher. After sealing the chamber, the volume produces the desired V/L value. The temperature of the measuring chamber is then regulated to the measuring temperature. After the temperature and pressure equilibrium, the measured pressure is recorded as the VPCRX of the sample. The test specimen shall be mixed during the measuring procedure by shaking the measuring chamber to achieve pressure equilibrium in a reasonable time of 5 to 30min. For results related to Test Method D323, the final volume of the measuring chamber shall be five times the test specimen volume and the measuring temperature shall be 37.8℃.
