ASTM D2603 – Standard Test Method for Sonic Shear Stability of Polymer-Containing Oils Description: Significance and Use 4.1 This test method permits the evaluation of shear stability with minimum interference from thermal and oxidative factors which may be present in some applications. Within the limitations expressed in the scope of this test method, it has been …
ASTM D2598 – Standard Practice for Calculation of Certain Physical Properties of Liquefied Petroleum (LP) Gases from Compositional Analysis Description: Significance and Use 4.1 Vapor pressure is an important specification property of commercial propane, special duty propane, propane/butane mixtures, and commercial butane that assures adequate vaporization, safety, and compatibility with commercial appliances. Relative density, while not …
ASTM D2596 – Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method) Description: Significance and Use 5.1 This test method, used for specification purposes, differentiates between lubricating greases having low, medium, and high level of extreme-pressure properties. The results do not necessarily correlate with results from service.4 5.2 It is noted that lubricating …
ASTM D2595 – Standard Test Method for Evaporation Loss of Lubricating Greases Over Wide-Temperature Range Description: Significance and Use 5.1 The loss of volatile materials from greases and oils can adversely affect the original performance characteristics of a lubricant and, therefore, could be a significant factor in evaluating a lubricant for a specific use. Such volatiles …
ASTM D2594 – Standard Test Method for Stretch Properties of Knitted Fabrics Having Low Power Description: Significance and Use 5.1 Fabric stretch and fabric growth are useful in selection of fabrics that are required to stretch, but also recover to their original shape. 5.1.1 In apparel, fabric stretch can be caused by a variety of factors. A …
ASTM D2584 – Standard Test Method for Ignition Loss of Cured Reinforced Resins Description: Significance and Use 4.1 This test method is used to obtain the ignition loss of a cured reinforced resin sample. Note 2: The basic concept of burning off of the organic matrix of a reinforced polymer composite has also been shown to be …
ASTM D2583 – Standard Test Method for Indentation Hardness of Rigid Plastics by Means of a Barcol Impressor Description: Significance and Use 5.1 The Barcol Impressor is portable and therefore suitable for testing the hardness of fabricated parts and individual test specimens for production control purposes. 5.2 Before proceeding with this test method, reference shall be made …
ASTM D2582 – Standard Test Method for Puncture-Propagation Tear Resistance of Plastic Film and Thin Sheeting Description: Significance and Use 4.1 The puncture-propagation of tear test measures the resistance of a material to snagging, or more precisely, to dynamic puncture and propagation of that puncture resulting in a tear. Failures due to snagging occur in a …
ASTM D2578 – Standard Test Method for Wetting Tension of Polyethylene and Polypropylene Films Description: Significance and Use 5.1 When a drop of liquid rests on the surface of a solid, and a gas is in contact with both, the forces acting at the interfaces must balance. These forces can be represented by surface energies acting …
ASTM D2574 – Standard Test Method for Resistance of Emulsion Paints in the Container to Attack by Microorganisms Description: Significance and Use 4.1 Spoilage of paint in the container can result in putrefaction, lowered pH, gas formation, and decrease in viscosity. This test method provides a standard procedure for the evaluation of the resistance of emulsion …
