ASTM D4959 – Standard Test Method for Determination of Water Content of Soil By Direct Heating Description: Significance and Use 5.1 The water content of a soil is used throughout professional practice both in the laboratory and in the field. The use of Test Methods D2216 for water content determination can be time consuming and there are occasions …
ASTM D4953 – Standard Test Method for Vapor Pressure of Gasoline and Gasoline-Oxygenate Blends (Dry Method) Description: Significance and Use 5.1 Vapor pressure is an important physical property of liquid spark-ignition engine fuels. It provides an indication of how a fuel will perform under different operating conditions. For example, vapor pressure is a factor in determining …
ASTM D4952 – Standard Test Method for Qualitative Analysis for Active Sulfur Species in Fuels and Solvents (Doctor Test) Description: Significance and Use 5.1 Sulfur present as mercaptans or as hydrogen sulfide in distillate fuels and solvents can attack many metallic and non-metallic materials in fuel and other distribution systems. A negative result in the doctor …
ASTM D4951 – Standard Test Method for Determination of Additive Elements in Lubricating Oils by Inductively Coupled Plasma Atomic Emission Spectrometry Description: Significance and Use 4.1 This test method usually requires several minutes per sample. This test method covers eight elements and thus provides more elemental composition data than Test Method D4628 or Test Methods D4927. In addition, this …
ASTM D4950 – Standard Classification and Specification for Automotive Service Greases Description: Scope 1.1 This specification covers lubricating greases suitable for the periodic relubrication of chassis systems and wheel bearings of passenger cars, trucks, and other vehicles. 1.2 This specification defines the requirements used to describe the properties and performance characteristics of chassis greases and wheel bearing …
ASTM D495 – Standard Test Method for High-Voltage, Low-Current, Dry Arc Resistance of Solid Electrical Insulation Description: Significance and Use 4.1 The high-voltage, low-current type of arc resistance test is intended to simulate only approximately such serviceconditions as exist in alternating current circuits operating at high voltage, but at currents limited to units and tens of …
