ASTM D848 – Standard Test Method for Acid Wash Color of Industrial Aromatic Hydrocarbons Description: Significance and Use 5.1 This test method is suitable for setting specifications on the materials referenced in 1.1. It may also be used as an internal quality control tool and in development or research work. 5.2 The color developed in the acid layer …
ASTM D828 – Standard Test Method for Tensile Properties of Paper and Paperboard Using Constant-Rate-of-Elongation Apparatus Description: Significance and Use 4.1 The tensile properties measured in this test method are fundamental properties associated with the manufacture, or end use, or both, of paper and paper products. It is possible for products to be influenced by, or …
ASTM D792 – Standard Test Methods for Density and Specific Gravity (Relative Density) of Plastics by Displacement Description: Significance and Use 5.1 The specific gravity or density of a solid is a property that is conveniently measured to identify a material, to follow physical changes in a sample, to indicate degree of uniformity among different sampling …
ASTM D785 – Standard Test Method for Rockwell Hardness of Plastics and Electrical Insulating Materials Description: Significance and Use 4.1 A Rockwell hardness number is a number derived from the net increase in depth impression as the load on an indenter is increased from a fixed minor load to a major load and then returned to …
ASTM D746 – Standard Test Method for Brittleness Temperature of Plastics and Elastomers by Impact Description: Significance and Use 5.1 This test method establishes the temperature at which 50 % of the specimens tested would probably fail when subjected to the conditions specified herein. The test provides for the evaluation of long-time effects such as crystallization, or …
ASTM D664 – Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration Description: Significance and Use 5.1 New and used petroleum products, biodiesel, and blends of biodiesel may contain acidic constituents that are present as additives or as degradation products formed during service, such as oxidation products. The relative amount of these materials …
ASTM D638 – Standard Test Method for Tensile Properties of Plastics Description: Significance and Use 4.1 This test method is designed to produce tensile property data for the control and specification of plastic materials. These data are also useful for qualitative characterization and for research and development. 4.2 Some material specifications that require the use of this …
ASTM D624 – Standard Test Method for Tear Strength of Conventional Vulcanized Rubber and Thermoplastic Elastomers Description: Significance and Use 5.1 Vulcanized rubber and thermoplastic elastomers (TPE) often fail in service due to the generation and propagation of a special type of rupture called a tear. This test method measures the resistance to tearing action. 5.2 Tear …
ASTM D374 – Standard Test Methods for Thickness of Solid Electrical Insulation Description: Significance and Use 5.1 Some electrical properties, such as dielectric strength, vary with the thickness of the material. Determination of certain properties, such as relative permittivity (dielectric constant) and volume resistivity, usually require a knowledge of the thickness. Design and construction of electrical …
ASTM D732 – Standard Test Method for Shear Strength of Plastics by Punch Tool Description: Significance and Use 4.1 Shear strength obtained by the use of punch-type tooling is one of the recognized methods of comparing materials, or obtaining data for engineering design purposes, or both. However, it must be recognized that for end-use applications there …
