1.1 This test method covers the determination of the pore size characteristics of geotextiles using an optical method and image analysis. 1.2 This method has been developed for determination of the Image Opening Size (IOS) of knitted geotextiles by image analysis. Other properties may be...
5.1 This test method is used to determine the mechanical properties in flexure of engineered ceramic components with multiple longitudinal hollow channels, commonly described as "honeycomb" channel architectures. The components generally have 30?% or more porosity and the cross-sectional...
4.1 This guide is intended as a source of tutorial and reference information that can be used during establishment of computed radiography techniques and procedures by qualified CR personnel for specific applications. All materials presented within this guide may not be suited for all...
3.1 The purpose of this standard is to provide uniform terminology used in the development of methods and standards relating to ASTM Committee E64 on Stormwater Control Measures (SCMs).
1.1 This test method covers the procedure for determining the volume resistivity, measured longitudinally, of extruded crosslinked and thermoplastic semiconducting, conductor and insulation shields for wire and cable. 1.2 In common practice the conductor shield is often...
1.1 As the General Accountability Office (GAO) reported in 2018 (2), the discovery of toxic levels of lead in drinking water in Flint, Michigan in 2015 renewed awareness about the risks that lead poses to public health. Exposure to lead can result in elevated blood lead levels and negative...
1.1 This test method covers the measurement of sound absorption in a reverberation room by measuring decay rate. Procedures for measuring the absorption of a room, the absorption of an object, such as an office screen, and the sound absorption coefficients of a specimen of sound absorptive...
1.1 This practice describes a procedure for obtaining stereological measurements that describe basic characteristics of the morphology of indigenous inclusions in steels and other metals using automatic image analysis. The practice can be applied to provide such data for any discrete second...
1.1 This terminology standard defines abbreviations and terms specific to uninsulated electrical conductors. For terms relating to superconductors, see Terminology B713. 1.2 This international standard was developed in accordance with internationally recognized principles on standardization...
5.1 Qualitative measurement of "nodularity" and "nodule count" using visual estimations has been practiced for many years. These methods suffer from poor reproducibility and repeatability. The introduction of computer-aided image analysis enables metallographers to measure and...
1.1 These test methods cover the determination of the radiopacity of materials and products utilizing X-ray based techniques, including fluoroscopy, angiography, CT (computed tomography), and DEXA (dual energy X-ray absorptiometry), also known as DXA, The results of these measurements...
1.1 This guide covers general guidelines for the in vivo assessment of tissue-engineered medical products (TEMPs) intended to repair or regenerate bone. TEMPs included in this guide may be composed of natural or synthetic biomaterials (biocompatible and biodegradable) or composites thereof,...
1.1 This specification covers standardizing the dimensions and materials for the manufacture of round wood dowels (pegs) used in the fabrication of connections in wood construction. The referencing of this specification in design, construction, and purchase order documents is intended...
1.1 This classification system covers liquid crystal polymeric (LCP) materials suitable for injection molding and extrusion. This classification system allows the use of liquid crystal polymers that are recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or a combination...
1.1 This test method covers the determination of the Image Opening Size (IOS) of a geotextile by image analysis. 1.2 This test method shows values in both SI units and inch-pound units. SI units is the technically correct name for the system of metric units known as the International System...
5.1 Material resistance to photodegradation caused by exposure to artificial UVC light sources is a growing concern due to the use of ultraviolet germicidal irradiation (UVGI) to mitigate the spread of infectious diseases. 5.2 Materials and products intended for direct sunlight exposure are...
1.1 This test method provides guidance to the methodology used in the measurement of building interior sound levels. 1.2 This test method describes procedures for measuring sound in enclosed residential spaces produced by built-in utilities and major appliances such as plumbing, heating,...
1.1 This standard is a user guide, which is intended to serve as a tutorial for selection and use of various digital detector array systems nominally composed of the detector array and an imaging system to perform digital radiography. This guide also serves as an in-detail reference...
3.1 The oxidation of silicon carbide refractories at elevated temperatures is an important consideration in the application of these refractories. The product of oxidation is amorphous silica or cristobalite, depending upon the temperature at which oxidation takes place. This oxide formation is...
1.1 This test method describes the instrumental measurement of the colorimetric properties (CIE tristimulus values, luminance factors, and chromaticity coordinates) of fluorescent-retroreflective sheeting and marking materials when illuminated by daylight. 1.2 This test method is...
