ASTM D2265 High Temperature Dropping Point Apparatus
The dropping point is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control. The results are to be considered to have only limited significance with respect to service performance because dropping point is a static test.

ASTM D6184 Oil Separation from Lubricating Grease (Conical Sieve Method)
When a lubricating grease separates oil, the residual material changes in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are intended to correlate with oil separation that occurs in 35-lb pails of grease during storage. They are not intended to predict oil separation tendencies of grease under dynamic service conditions

ASTM D1404 Deleterious Particles In Lubricating Grease
The significance of the number of scratches as far as correlation with field performance is concerned has not been established. A particle which is abrasive to plastic will not necessarily be abrasive to steel or other bearing materials. Some correlation was obtained in that the contaminant used in Sample 3 had a greater wear rate in a laboratory ball bearing abrasive wear test than the contaminant in Sample 2.

ASTM D217 Cone Penetration For Grease
Cone penetration test results provide one measure of the consistency of a grease. Worked penetration results are required to determine to which NLGI consistency grade a grease belongs. Undisturbed penetration results provide a means of evaluating the effect of storage conditions on grease consistency

ASTM D1094 Automatic Water Reaction Of Aviation Fuels
A sample of the fuel is shaken, using a standardized technique, at room temperature with a phosphate buffer solution in scrupulously cleaned glassware. The cleanliness of the glass cylinder is tested. The change in volume of the aqueous layer and the appearance of the interface are taken as the water reaction of the fuel.

ASTM D1500 ASTM Color Of Petroleum Products
Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic, since color is readily observed by the user of the product. In some cases, the color may serve as an indication of the degree of refinement of the material. When the color range of a particular product is known, a variation outside the established range may indicate possible contamination with another product. However, color is not always a reliable guide

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.
