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 D4145 – Standard Test Method for Coating Flexibility of Prepainted Sheet Description: Significance and Use 4.1 Organic coatings on precoated sheet are subjected to stresses when fabricated into products by roll forming, brake bending, or other deformation processes. These stresses can exceed the flexibility or adhesive strength of the coating, resulting in fracture of the …
ASTM D4141 – Standard Practice for Conducting Black Box and Solar Concentrating Exposures of Coatings Description: Significance and Use 5.1 As with any accelerated test, the increase in rate of weathering compared to in-service exposure is material dependent. Therefore, no single acceleration factor can be used to relate two different types of outdoor weathering exposures. The …
ASTM D4138 – Standard Practices for Measurement of Dry Film Thickness of Protective Coating Systems by Destructive, Cross-Sectioning Means Description: Significance and Use 5.1 Many coating properties are markedly affected by the film thickness of the dry film such as adhesion, flexibility, and harness. To be able to compare results obtained by different operators, it is …
ASTM D4130 – Standard Test Method for Sulfate Ion in Brackish Water, Seawater, and Brines (Withdrawn 2024) Description: Significance and Use 5.1 The determination of sulfate and other dissolved constituents is important in identifying the source of brines produced during the drilling and production phases of crude oil or natural gas. Scope 1.1 This test method covers …
ASTM D413 – Standard Test Methods for Rubber Property—Adhesion to Flexible Substrate Description: Significance and Use 4.1 These test methods are used to ensure the quality of a product by determining the force per unit width required to separate a rubber layer from a flexible substrate such as fabric, fibre, wire, or sheet metal. The acceptable …
ASTM D4129 – Standard Test Method for Total and Organic Carbon in Water by High Temperature Oxidation and by Coulometric Detection Description: Significance and Use 5.1 This test method is necessary because of the need for rapid reliable tests for carbonaceous material in waters and sediments. 5.2 It is used for determining the concentration of organic carbon …
ASTM D4128 – Standard Guide for Identification and Quantitation of Organic Compounds in Water by Combined Gas Chromatography and Electron Impact Mass Spectrometry Description: Significance and Use 5.1 With the common occurrence in water of organic compounds, some of which are toxic, it is often necessary to identify the specific compounds present and to determine the …
ASTM D4124 – Standard Test Method for Separation of Asphalt into Four Fractions Description: Significance and Use 5.1 This test method separates asphalts into four well-defined fractions. Analysis of these fractions can be used to evaluate asphalt composition (1, 2).4 For example, one can compare the ratios of the fractions with other asphalt systems to evaluate processing and aging …
ASTM D412 – Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers—Tension Description: Significance and Use 5.1 All materials and products covered by these test methods must withstand tensile forces for adequate performance in certain applications. These test methods allow for the measurement of such tensile properties. However, tensile properties alone may not directly relate to …
