Standard Guide for Measuring Roundness of Glass Spheres Using a Flowing Stream Digital Image Analyzer
Abstract: 4.1 The roundness of glass beads has a significant influence on the retroreflective efficiency of a pavement marking system. 4.2 The guide is for the characterization of the roundness of glass beads for the purpose of ... -
Standard Test Methods for Integrity Testing of Concrete Deep Foundations by Thermal Methods
Abstract: 5.1 Temperature measurements taken from a thermal probe lowered into access ducts in the deep foundation element, or from embedded thermal sensors distributed along the length, or from embedded fiber optic cables can ... -
Standard Test Method for Water in Ethanol and Hydrocarbon Blends by Karl Fischer Titration
Abstract: 5.1 Blends of fuel ethanol and hydrocarbon have a limited solvency for water that is dependent upon temperature and the ratio of ethanol to hydrocarbon. Good handling practices are important during the blending, storage, ... -
Standard Practice for Inductive Wear Debris Sensors in Gearbox and Drivetrain Applications
Abstract: 5.1 This practice is intended for the application of online, full-flow, or bypass, or kidney loop sampling of wear debris via inductive sensors for gearbox and drivetrain applications. 5.2 Periodic sampling and analysis ... -
Standard Test Method for Bond Strength of Fiber-Reinforced Polymer Matrix Composite Bars to Concrete by Pullout Testing
Abstract: 5.1 The behavior of the bond between concrete and FRP reinforcing bars is an important performance aspect that has been used in material specifications and design standards. This test method serves as a means for uniformly ... -
Standard Guide for Placement of Intentional Leaks During Electrical Leak Location Surveys of Geomembranes
Abstract: 4.1 Geomembranes are used as low-permeability barriers to control liquids from leaking from landfills, ponds, and other containments. The liquids may contain contaminants that, if released, can cause damage to the environment. ... -
Standard Test Method for Determination of Light Hydrocarbons in Stabilized Crude Oils by Gas Chromatography
Abstract: 5.1 Knowledge of the boiling point distribution of stabilized crude oils is important for the marketing, scheduling, and processing of crude oil in the petroleum industry. Test Method D7169 and IP 545 purport to give such ... -
Standard Specification for Refined Lead
Abstract: This specification covers refined lead in pig, block, or hog forms. Lead shall be supplied in commercial standard forms or shapes requested by the purchaser in the following grades: low-bismuth low-silver pure lead, refined ... -
Standard Guide for Selection of Substitute, Non-hazardous, Liquid Filling Substances for Packagings Subjected to the United Nations Performance Tests
Abstract: 5.1 Regulations prescribing the test procedures for hazardous materials packaging allow for the substitution of non-hazardous fill materials for packaging performance tests with certain limitations as outlined in 49 CFR ... -
Standard Guide for Electronic Methods for Detecting and Locating Leaks in Roofing and Waterproofing Membranes
Abstract: 4.1 The failure to correct membrane defects during and as soon as possible after its installation can cause premature failure of the membrane. Problems include design deficiencies, faulty application of the membrane system, ... -
Standard Test Method for Determination of Total Organic Halides, Total Non-Methane Hydrocarbons, and Formaldehyde in Hydrogen Fuel by Gas Chromatography/Mass Spectrometry
Abstract: 5.1 Low operating temperature fuel cells such as Proton Exchange Membrane Fuel Cells (PEMFCs) require high purity hydrogen for optimal performance and longevity. Analysis of hydrogen is necessary for ensuring feed gas of ... -
Standard Test Method for Determining the Concentration of Pipeline Drag Reducer Additive in Aviation Turbine Fuels
Abstract: 5.1 DRA is frequently added into multiproduct pipelines to increase throughput or reduce energy requirements of fuel movement. Although these additives are not used in jet fuel, contamination can occur from other products ... -
Standard Practice for Xenon Arc Exposure Test with Enhanced Light and Water Exposure for Transportation Coatings
Abstract: 5.1 This test procedure is used to simulate the physical and environmental stresses that a coating for exterior transportation applications (for example, automotive) is exposed to in a subtropical climate, such as southern ... -
Standard Test Methods for Measurement of Yield Stress of Paints, Inks and Related Liquid Materials
Abstract: 5.1 The yield stress of a material is a measure of the amount of force required to initiate movement of that material in a pipe, through a pump, or from nozzle. The yield stress also characterizes the ability of the material ... -
Standard Test Method for In-Place Density (Unit Weight) and Water Content of Soil Using an Electromagnetic Soil Density Gauge
Abstract: 5.1 The method described determines wet density and gravimetric water content by correlating complex impedance measurement data to an empirically developed model. The empirical model is generated by comparing the electrical ... -
Standard Test Method for Determination of Biodiesel (Fatty Acid Methyl Ester) and Triglyceride Content in Diesel Fuel Oil Using Mid-Infrared Spectroscopy (FTIR Transmission Method)
Abstract: 5.1 Biodiesel is a fuel commodity primarily used as a value-added blending component with diesel fuel. 5.2 This test method is applicable for quality control in the production and distribution of diesel fuel and biodiesel ... -
Standard Practice for Thermal Oxidative Stability Measurement via Quartz Crystal Microbalance
