Standard Test Method for Silica—pH Value
Abstract: 3.1 The pH level of silica, as measured by this test method, is known to affect the vulcanization of some rubber compounds. Refer to Test Method E70 for a fuller understanding of pH and a more detailed procedure for making ... -
Standard Specification for Ultra-High-Molecular-Weight Polyethylene (UHMW-PE) Solid Plastic Shapes
Abstract: This specification focuses on the classification, and requirements and test methods for the material and properties of solid plastic shapes manufactured from ultra-high-molecular-weight polyethylene (UHMW-PE), both virgin ... -
Standard Test Method for Bulk Density of Tapered Paintbrush Filaments
Abstract: 3.1 Filaments are available in a variety of cross-sections and materials. A measure of bulk density permits the brushmaker to estimate the weight of filament required to prepare a given number of brushes. -
Standard Test Method for Evaluation of Automotive Engine Oils in the Sequence VIII Spark-Ignition Engine (CLR Oil Test Engine)
Abstract: 5.1 This test method is used to evaluate automotive engine oils for protection of engines against bearing weight loss. 5.2 This test method is also used to evaluate the SIG capabilities of multiviscosity-graded oils. ... -
Standard Guide for Repair and Recoat of Spray Polyurethane Foam Roofing Systems
Abstract: 4.1 This guide outlines general procedures and precautions necessary for correct and safe repair and recoat of SPF roofing systems. 4.2 This guide is not all inclusive; this guide is intended to supplement detailed ... -
Standard Practice for Full-Scale Chamber Determination of Volatile Organic Emissions from Indoor Materials/Products
Abstract: 5.1 VOCs emitted from materials/products affect indoor air quality (IAQ) in buildings. To determine the impact of these emissions on IAQ, it is necessary to know their emission rates over time. This practice provides ... -
Standard Test Method for Determining the Flexural Creep Stiffness of Asphalt Binder Using the Bending Beam Rheometer (BBR)
Abstract: 5.1 The stiffness and m-value describe the low-temperature stress-strain-time response of asphalt binders. The stiffness and m-value are fundamental material properties and may be used to characterize the linear viscoelastic ... -
Standard Guide for Evaluation of Aqueous Polymer Quenchants
Abstract: 4.1 The significance and use of each test method will depend on the system in use and the purpose of the test method listed under Section 7. Use the most recent editions of the test methods. -
Standard Practice for Accelerated Weathering of Pressure-Sensitive Tapes by Xenon-Arc Exposure Apparatus
Abstract: 4.1 This practice describes one method for accelerated weathering of pressure-sensitive tapes used primarily for packaging. It is not intended for evaluation the weathering characteristics of pressure-sensitive tapes used ... -
Standard Test Method for High Temperature Universal Oxidation Test for Turbine Oils
Abstract: 5.1 Degradation of fluid lubricants because of oxidation or thermal breakdown can result in fluid thickening or in the formation of acids or insoluble solids and render the fluid unfit for further use as a lubricant. ... -
Standard Test Method for Fatigue of Tire Cords (Disc Fatigue Test)
Abstract: 5.1 This test method is not recommended for acceptance testing of commercial shipments in the absence of reliable information on between-laboratory precision. 5.1.1 If there are differences of practical significance between ... -
Standard Practice for Fiber Reinforcement Orientation Codes for Composite Materials
Abstract: 4.1 The purpose of a laminate orientation code is to provide a simple, easily understood method of describing the lay-up of a laminate. The laminate orientation code is based largely on a combination of industry practice ... -
Standard Guide for the Selection of Test Methods for Flexible Polypropylene Geomembranes
Abstract: 4.1 To evaluate flexible polypropylene properly, tests must be performed according to specific test methods and procedures. Failure to follow this guide can result in data not representative of the material's characteristics ... -
Standard Test Method for Determining the Integrity of Nonreinforced Geomembrane Seams Produced Using Thermo-Fusion Methods
Abstract: 4.1 The use of geomembranes as barrier materials to restrict liquid migration from one location to another in soil and rock has created a need for a standard test method to evaluate the quality of geomembrane seams produced ... -
Standard Test Method for Estimation of Engine Oil Volatility by Capillary Gas Chromatography
Abstract: 5.1 The determination of engine oil volatility at 371 °C (700 °F) is a requirement in some lubricant specifications. 5.2 This test method is intended as an alternative to Test Methods D5800 and the Noack method for the ... -
