5.1 The KR curve characterizes the resistance to fracture of materials during slow, stable crack extension and results from the growth of the plastic zone ahead of the crack as it extends from a fatigue precrack or sharp notch. It provides a record of the toughness development as a crack is driven...

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 health...

This practice covers the acceptance criteria for surface inspection of investment castings through visual examination. The material shall conform to Levels II, III, and IV acceptance criteria for features of surface pits, positive metal, parting line and ejector pin marks, gate height, and...

4.1 Due to the variety of small bone fractures, plates used for the fixation of these fractures come in a variety of shapes and configurations. Table 1 categorizes the plate types for each anatomical area. Flat plates are the simplest; see Fig. 2 for an example of a basic flat plate. Many other...

1.1 These test methods cover the determination of the electrical conductivity and resistivity of water. The following test methods are included: Range Sections Test Method A-Field and Routine Laboratory 10 to 200?000 12 to 18 ?Measurement of Static (Non-Flowing) Samples ?μS/cm Test Method...

1.1 This test method covers two procedures for determining the compressive resistance of thermal insulations. 1.1.1 Procedure A covers thermal insulations having an approximate straight-line portion of a load-deformation curve, with or without an identifiable yield point as shown in Figs. 1...

This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: test method...

5.1 This test method can be used to determine scuffing temperature limit and the evolution of coefficient of friction of lubricating oils with increasing temperatures for use in tribological contacts in which high-speed vibrational or start-stop motions are present for extended periods of time...

5.1 On-line, at-line, in-line, CFMS, and other near-real time monitoring systems that measure fuel gas characteristics, such as the sulfur content, are prevalent in the natural gas and fuel gas industries. The installation and operation of particular systems vary on the...

5.1 Most coatings are designed for a specific baking time and temperature. For a variety of reasons (line stoppages, rerouting back through ovens, oven overheating, etc.) the prescribed time or temperature, or both, of the bake is often exceeded. This practice has been found to be useful in...

This SAE Standard covers the measurement of voltage transient immunity and within the applicable frequency ranges, audio (AF) and radio frequency (RF) immunity, and conducted and radiated emissions. By reference, ISO 11452-3, ISO 11452-7, ISO 11452-8, ISO 11452-10, ISO 11452-11, ISO 11452-2, and...

1.1 This specification provides the minimum requirements for design fabrication, pressure rating, and testing for line-blind valves. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are...

1.1 This test method defines procedures for testing vitrified clay pipe lines, using low-pressure air, to demonstrate the integrity of the installed line. Refer to Practice C12. 1.2 This test method shall be performed on lines after connection laterals, if any, have been plugged and braced...

This specification describes requirements and test methods for the qualification of Polyamide 11 (PA 11) bodied mechanical fittings for use with outside diameter controlled PA 11 pipe, and nominal 2 pipe size (IPS) and smaller. In addition, it specifies general requirements of the material from...

1.1 This classification system covers polyamide materials suitable for molding and extrusion. Some of these compositions are also suitable for application from solution. 1.2 The properties included in this classification system are those required to identify the compositions covered. Other...

1.1 This classification system covers requirements for plasticized cellulose acetate butyrate thermoplastic compounds suitable for injection molding and extrusion. These compounds have a butyryl content less than 38?% and an acetyl content less than 15?% and can contain dyes and pigments. This...

1.1 This specification covers insulating rods and foam-filled tubes made from fiberglass-reinforced plastic (FRP) that are intended for use in live line tools. 1.2 This specification does not include insulating foam-filled tubes and rods from other materials. Specifications for fittings and...

1.1 This guide covers only S-N and e-N relationships that may be reasonably approximated by a straight line (on appropriate coordinates) for a specific interval of stress or strain. It presents elementary procedures that presently reflect good practice in modeling and analysis. However,...

4.1 The procedure for establishing the long-term pressure rating of fittings starts with an extrapolation of a regression line that is based on fitting failure data with respect to time, when assemblies are tested in accordance with Test Method D1598. The pressure-versus time to failure data...

3.1 An adhesive symbol provides an efficient means of placing complete information about adhesives on engineering drawings. The joint is the basis of reference for the symbol to which the arrow line is pointed. The reference line of the symbol is used to designate the type of adhesive...
