  • FRETTING WEAR PROTECTION BY LUBRICATING GREASES: ASTM D4170 FRETTING WEAR PROTECTION BY LUBRICATING GREASES: ASTM D4170EXPLANATIONThis test method is used to evaluate the property of lubricating greases to protect oscillating bearings from fretting wear. It is used for specification purposes, and differentiates between greases allowing low, medium, and high amounts ...
  • FREEZING POINT OF HIGH PURITY HYDROCARBONS: ASTM D1015 FREEZING POINT OF HIGH PURITY HYDROCARBONS: ASTM D1015EXPLANATIONA knowledge of the purity of the hydrocarbons is often needed to help control their manufacture and to determine their suitability for use as reagent chemicals or for conversion to other chemical intermediates or finished products. The ...
  • FREEZING POINT: ASTM D5972 FREEZING POINT: ASTM D5972(Equivalent Test Method: IP 435)This is an automated phase transition method used in the temperature range -80 to 20° C. Results by this test method have a resolution of 0.1° C, and have a precision better than that of Test Method ASTM D2386. It also eliminates most of the ...
  • FREEZING POINT: ASTM D5901 FREEZING POINT: ASTM D5901(Equivalent Test Method: IP 434)This is an automated optical method used for the temperature range 0 to -70° C. Results by this test method have a resolution of 0.1° C. A 25-mL portion of the fuel is placed in a test chamber, which is cooled while continuously being stirred ...

Solid hydrocarbon crystals can restrict the flow of fuel ...
  • FOAMING TENDENCY HIGH TEMPERATURE FOAMING TENDENCY: ASTM D6082 FOAMING TENDENCY HIGH TEMPERATURE FOAMING TENDENCY: ASTM D6082EXPLANATIONThis test commonly known as the "Sequence IV" foam test is the high temperature version of Test Method ASTM D892. This was originally a Ford test, which has now been accepted by all OEMs in a slightly modified form. The test determines ...
  • FOAMING TENDENCY OF LUBRICATING OILS: ASTM D892 FOAMING TENDENCY OF LUBRICATING OILS: ASTM D892(Equivalent Test Methods: IP 146, ISO 6247, DIN 51566, and JIS K 2518)EXPLANATIONThe tendency of oils to foam can be a serious problem in systems such as high-speed gearing, high-volume pumping, and splash lubrication. Inadequate lubrication, cavitation, ...
  • FOAMING TENDENCY IN AQUEOUS MEDIA: ASTM D3519 AND ASTM D3601 FOAMING TENDENCY IN AQUEOUS MEDIA: ASTM D3519 AND ASTM D3601EXPLANATIONThe results from these tests are useful as guides in determining the tendency of a water-based metal working coolant to produce foam under low or high shear conditions. No correlation with changes in heat transfer, pumpability, or ...
