ASTM D2638 – Standard Test Method for Real Density of Calcined Petroleum Coke by Helium Pycnometer Description: Significance and Use 5.1 The real density of calcined petroleum coke directly influences the physical and chemical properties of the manufactured carbon and graphite artifacts for which it is used. Density, therefore, is a major quality specification of calcined …
ASTM D2632 – Standard Test Method for Rubber Property—Resilience by Vertical Rebound Description: Significance and Use 4.1 Resilience is a function of both dynamic modulus and internal friction of a rubber. It is very sensitive to temperature changes and to depth of penetration of the plunger. Consequently, resilience values from one type of rebound instrument may …
ASTM D2626 – Standard Specification for Asphalt-Saturated and Coated Organic Felt Base Sheet Used in Roofing Description: Abstract This specification covers the standard for asphalt-saturated and coated organic felt base sheet with mineral surfacing on the top side, with or without perforations. These sheets are proposed for use as the first ply of a built-up …
ASTM D2625 – Standard Test Method for Endurance (Wear) Life and Load-Carrying Capacity of Solid Film Lubricants (Falex Pin and Vee Method) Description: Significance and Use 5.1 This test method differentiates between bonded solid lubricants with respect to their wear life and load-carrying capacity. If the test conditions are changed, wear life may change and relative …
ASTM D2624 – Standard Test Methods for Electrical Conductivity of Aviation and Distillate Fuels Description: Significance and Use 5.1 The ability of a fuel to dissipate charge that has been generated during pumping and filtering operations is controlled by its electrical conductivity, which depends upon its content of ion species. If the conductivity is sufficiently high, …
ASTM D2622 – Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry Description: Significance and Use 5.1 This test method provides rapid and precise measurement of total sulfur in petroleum and petroleum products with a minimum of sample preparation. A typical analysis time is 1 min to 2 min per sample. 5.2 The quality …
ASTM D2621 – Standard Test Method for Infrared Identification of Vehicle Solids From Solvent-Reducible Paints Description: Significance and Use 5.1 The ability to qualitatively identify paint vehicles is useful for characterizing unknown or competitive coatings, for complaint investigations, and for in-process control. Scope 1.1 This test method covers the qualitative characterization or identification of separated paint vehicle …
ASTM D2619 – Standard Test Method for Hydrolytic Stability of Hydraulic Fluids (Beverage Bottle Method) Description: Significance and Use 4.1 This test method differentiates the relative stability of hydraulic fluids in the presence of water under the conditions of the test. Hydrolytically unstable hydraulic fluids form acidic and insoluble contaminants which can cause hydraulic system malfunctions …
ASTM D2617 – Standard Test Method for Total Ash in Leather Description: Significance and Use 4.1 This test method is useful in determining the approximate amount of nonvolatile inorganic material in leather. This may be in the form of salts or oxides of the elements. In a mixed chrome tannage, the approximate percentage of other elements …
ASTM D2616 – Standard Test Method for Evaluation of Visual Color Difference With a Gray Scale Description: Significance and Use 5.1 The total perceived color difference between two non-self-luminous specimens is compared as an equivalent lightness difference between two neutral gray specimens on a gray scale. A fundamental assumption is made that the total color difference …
