ASTM D4892 – Standard Test Method for Density of Solid Pitch (Helium Pycnometer Method) Description: Significance and Use 5.1 This test method is useful in characterizing pitches as one element in establishing uniformity of shipments and sources of supply. With this method, the density is determined to two decimal places, which is sufficient for most applications. …
ASTM D4739 – Standard Test Method for Base Number Determination by Potentiometric Hydrochloric Acid Titration Description: Significance and Use 5.1 New and used petroleum products can contain basic constituents that are present as additives. The relative amount of these materials can be determined by titration with acids. The base number is a measure of the amount …
ASTM D4629 – Standard Test Method for Trace Nitrogen in Liquid Hydrocarbons by Syringe/Inlet Oxidative Combustion and Chemiluminescence Detection Description: Significance and Use 4.1 Some process catalysts used in petroleum and chemical refining may be poisoned when even trace amounts of nitrogenous materials are contained in the feedstocks. This test method can be used to determine …
ASTM D4603 – Standard Test Method for Determining Inherent Viscosity of Poly(Ethylene Terephthalate) (PET) by Glass Capillary Viscometer Description: Significance and Use 5.1 The inherent viscosity is relatable to the composition and molecular weight of a polyester resin. It must be controlled so that the processability and end properties of the resin remain in a desired …
ASTM D4440 – Standard Test Method for Plastics: Dynamic Mechanical Properties Melt Rheology Description: Significance and Use 5.1 This test method provides a simple means of characterizing the important rheological properties and viscosity of thermoplastic polymers using very small amounts of material (approximately 25 to 50 mm in diameter by 1 to 3 mm in thickness …
ASTM D4287 – Standard Test Method for High-Shear Viscosity Using a Cone/Plate Viscometer Description: Significance and Use 4.1 The viscosity value obtained by this test method gives information about the flow properties of the material under high-shear conditions similar to those encountered during application: brushing (see Test Method D4958), spraying, electrostatic disk, or roll coating. 4.2 This test …
ASTM D4157 – Standard Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method) Description: Significance and Use 5.1 The measurement of the resistance to abrasion of textile and other materials is very complex. The resistance to abrasion is affected by many factors, such as the inherent mechanical properties of the fibers; the dimensions of …
ASTM D4060 – Standard Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser Description: Significance and Use 5.1 Coating on substrates can be damaged by abrasion during its service life. This test method has been useful in evaluating the abrasion resistance of coatings. Ratings produced by this test method have correlated well with …
ASTM D4052 – Standard Test Method for Density, Relative Density, and API Gravity of Liquids by Digital Density Meter Description: Significance and Use 5.1 Density is a fundamental physical property that can be used in conjunction with other properties to characterize both the light and heavy fractions of petroleum and petroleum products. 5.2 Determination of the density …
ASTM D4034 – Standard Test Method for Resistance to Yarn Slippage at the Sewn Seam in Woven Upholstery Fabrics (Withdrawn 2001) Description: Scope 1.1 This test method covers the measurement of the resistance to slippage of warp yarns or filling yarns in woven upholstery fabrics, when testing for yarn slippage at the seam. Note 1-This …
