ALKYL NITRATE IN DIESEL FUELS: D4046
ALKYL NITRATE IN DIESEL FUELS: D4046(Equivalent Tests: IP 430 and ISO 13759)EXPLANATIONAlkyl nitrate is added to diesel fuel to improve cetane number. This method can determine 0.03 to 0.30 volume percent of alkyl nitrate in diesel fuel and thus can serve as a basis for judging compliance with specifications ...

ADHESION OF SOLID FILM LUBRICANTS: D2510
ADHESION OF SOLID FILM LUBRICANTS: D2510EXPLANATIONEffective solid film lubricant coatings must adhere to surfaces to provide adequate lubrication in applications with restricted access where fluid lubricants cannot easily be replenished. Without this coating adhesion, metal to metal contact results ...

ACTIVE SULFUR IN CUTTING OILS: D1662
ACTIVE SULFUR IN CUTTING OILS: D1662EXPLANATIONThis test measures the amount of sulfur available to react with metallic surfaces to form solid lubricating aids at the temperature of the test. The rates of reaction are metal type, temperature, and time dependent. It has not been determined as to how the ...

ACIDITY OF HYDROCARBON LIQUIDS AND THEIR DISTILLATION RESIDUES: D1093
ACIDITY OF HYDROCARBON LIQUIDS AND THEIR DISTILLATION RESIDUES: D1093EXPLANATIONSome petroleum products are treated with mineral acid during the refining process. Any residual mineral acid in a petroleum product is undesirable. This test makes a qualitative determination of the acidity of hydrocarbon ...
-
ACIDITY IN AVIATION TURBINE FUEL: D3242
ACIDITY IN AVIATION TURBINE FUEL: D3242(Equivalent Tests: IP 354 and DIN 51558 T3)EXPLANATIONSome acids can be present in aviation turbine fuels due either to the acid treatment during the refining process or to naturally occurring organic acids. It's unlikely that significant acid contamination will ...

ACID NUMBER: D5770
ACID NUMBER: D5770ACID NUMBER BY SEMI-QUANTITATIVE MICRO DETERMINATION OF ACID NUMBER OF LUBE OILS DURING OXIDATION TESTING: D5770EXPLANATIONThis test method provides a means of monitoring the relative oxidation of lubricating oils by measuring changes in acid number, at different time intervals and ...
-
ACID NUMBER BY SEMI-MICRO COLOR INDICATOR TITRATION: D3339
ACID NUMBER BY SEMI-MICRO COLOR INDICATOR TITRATION: D3339(Equivalent Tests: IP 431 and ISO 7537)EXPLANATIONThis test method measures the acid number of oils obtained from laboratory oxidation test (Test Method D943) using smaller amounts of samples than those used in other acid number tests for Test ...
