Standard Practice for Fabrication of Neutron Radiographic Sensitivity Indicators

SIGNIFICANCE AND USE
5.1 The only truly valid image quality indicator is a material or component, equivalent to the part being neutron radiographed, with a known standard discontinuity, inclusion, omission, or flaw (reference standard comparison part). The SI is designed to substitute for the reference standard, providing qualitative information on hole and gap sensitivity in a single unit. Fabrication in accordance with this practice is vital for accurate and consistent measurements.  
5.2 This practice shall be followed for the fabrication of all SIs to be used with Test Method E545 to determine image quality in direct thermal neutron radiography. Devices constructed to previous versions of this practice, or Test Method E545 for devices built between 1981 and 1991, can also be used.
SCOPE
1.1 This practice covers the fabrication of Sensitivity Indicators (SI), which can be used to determine the relative quality of film radiographic images produced by direct, thermal neutron radiographic examination.  
1.2 Units—The values stated in inch-pound units are to be regarded as standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for the Qualification and Control of the Assisted Defect Recognition of Digital Radiographic Test Data

SIGNIFICANCE AND USE
5.1 This guide describes the recommended procedure for using software to assist with the identification of indications in digital radiographic images. Some of the concepts presented may be appropriate for other nondestructive test methods.  
5.2 When properly applied, the methods and techniques outlined in this guide offer radiographic testing practitioners the potential to improve inspection reliability, reduce inspection cycle time, and harness inspection statistics for improving manufacturing processes.  
5.3 The typical goal of a nondestructive test is to identify flaws that exceed the acceptance criteria. Due to the variability and uncertainty present in any inspection process, acceptance thresholds are established so that some acceptable components are discarded in an effort to prevent parts with discontinuities that exceed the acceptance criteria from entering service. This type of error, called a false positive, is considered less critical than a false negative error which would allow a nonconforming part into service. A successful application of AssistDR minimizes the false positive rate while reducing the false negative rate to levels appropriate for the intended application. The methods and techniques described in this guide facilitate achieving this desired outcome.  
5.4 With the advent of deep learning, convolutional neural networks, and other forms of artificial intelligence, scenarios become possible where an AssistDR system continues to evolve or learn after qualification for production use. This guide does not address learning-based AssistDR systems. This guide addresses only deterministic systems that have software code and parameters that are fixed after qualification. Note that this limitation does not prohibit the use of this guide for developing a qualification and usage strategy for software using deep learning technology. The training or learning process for the deep learning system would need to be completed before qualification and all ...
SCOPE
1.1 Assisted defect recognition (AssistDR) describes a class of computer algorithms that assist a human operator in making a determination about nondestructive test data. This guide uses the term AssistDR to describe those computer assisted evaluation algorithms and associated software. For the purposes of this guide, the usage of the words “defect,” “evaluate,” “evaluation,” etc., in no way implies that the algorithms are dispositioning or otherwise making an unaided final disposition. Depending on the application, AssistDR computer algorithms detect and optionally classify indications of defects, flaws, discontinuities, or other anomalous signals in the acquired images. Software that does make an unaided final disposition is classified as automated defect recognition (AutoDR). While the concepts discussed in this guide are pertinent to AutoDR applications, additional validation tests or controls may be necessary when implementing AutoDR.  
1.2 This guide establishes the minimum considerations for the radiographical examination of components using AssistDR for non-film radiographic test data. Most of the examples and discussion in this guide are built around two-dimensional test data for simplicity. The principles can be applied to three (volumetric computed tomography, for example) or higher dimensional test data.  
1.3 The methods and practices described in this guide are intended for the application of AssistDR where image analysis will aid a human operator in the detection and evaluation of indications. The degree to which AssistDR is integrated into the testing and evaluation process will help the user determine the appropriate levels of process qualification and control required. This guide is not intended for applications wishing to employ AutoDR in which there is no human review of the results.  
1.4 This guide applies to radiographic examination using an X-ray source. Some of the concepts presented may be ap...

Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...

ASTM F3565-23(Practice)
Standard Practice for Electrofusion Joining Polyethylene (PE) Pipe and Fittings for Pressure Pipe Service

SIGNIFICANCE AND USE
4.1 Using the procedures and apparatus in Sections 8 and 9 and the manufacturer's instructions, pressure-tight joints as strong as the pipe itself can be made between manufacturer-recommended combinations of pipe and fittings. See Specification F1055 for performance requirements of polyethylene electrofusion fittings.
SCOPE
1.1 This practice describes procedures for making joints suitable for pressure service with polyethylene (PE) pipe and fittings by means of electrofusion joining techniques in, but not limited to, a field environment. Other suitable electrofusion joining procedures are available from various sources including fitting manufacturers. This standard does not purport to address all possible electrofusion joining procedures, or to preclude the use of qualified procedures developed by other parties that have been proven to produce reliable electrofusion joints. (Note 1)
Note 1: Reference to the manufacturer in this practice refers to the electrofusion fitting manufacturer.  
1.2 The parameters and procedure are applicable only to joining polyethylene pipe and fittings (Note 2) which are intended for PE fuel gas pipe per Specification D2513 and PE potable water, sewer and industrial pipe manufactured per Specification F714, Specification D3035, Specification F2619, and AWWA C901 and C906.
Note 2: Commercially available materials classified with a thermoplastic pipe material designation code beginning with PE 14, PE 23, PE 24, PE 27, PE 33, PE 34, PE 36, and PE 46, and PE 47 in accordance with Specification D3350 and Terminology F412 are generally acceptable for electrofusion joining using this practice. Consult with the pipe or fitting manufacturer for specific compatibility information.  
1.3 Parts that are within the dimensional tolerances given in present ASTM specifications are required to produce sound joints between polyethylene pipe and fittings when using the joining techniques described in this practice.  
1.4 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 provided for information only and are not considered standard.  
1.5 The text of this practice references notes, footnotes, and appendices which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the practice.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determining Filtering Efficiency and Flow Rate of the Filtration Component of a Sediment Retention Device

SIGNIFICANCE AND USE
5.1 This test method is used to determine the filtering efficiency and flow rate of the filtration component of a sediment retention device, such as a silt fence, a silt barrier, or a silt curtain, for specific soil tested.  
5.2 This test method may be used for the design of the filtration component of a sediment retention device to meet requirements of regulatory agencies in filtering efficiency or flow rate for the specific soil tested.  
5.2.1 The designer can use this test method to determine the spacing between sediment retention devices.  
5.3 This test method is intended for performance evaluation, as the results will depend on the specific soil evaluated. Unless testing with the default soil is desired, it is recommended that the user or representative perform the test to pre-approve products, as sediment retention device manufacturers are not typically equipped to handle or test soil requirements.  
5.4 This test method provides a means of evaluating the filtration component of sediment retention devices with different soils under various conditions that simulate the conditions that exist in a sediment retention device installation. This test method may be used to simulate several storm events on the same sediment retention device specimen. Therefore, the number of times this test is repeated per specimen is dependent upon the user and the site conditions.
SCOPE
1.1 This test method is used to determine the filtering efficiency and the flow rate of the filtration component of a sediment retention device, such as a silt fence, silt barrier, or inlet protector.  
1.1.1 The results are shown as a percentage for filtering efficiency and cubic metres per square metre per minute (m3/m2/min) or gallons per square foot per minute (gal/ft2/min) for flow rate.  
1.1.2 The filtering efficiency indicates the percent of sediment removed from sediment-laden water.  
1.1.3 The flow rate is the average rate of passage of the sediment-laden water through the filtration component of a sediment retention device.  
1.2 This test method requires several specialized pieces of equipment, such as an integrated water sampler and an analytical balance, or a vacuum filtration system. At the client’s discretion, the test soil is either a site-specific soil or a soil that is representative of a target default gradation.  
1.3 The values stated in SI units are the standard, while the inch-pound units are provided for information. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM F2886-17(2023)(Specification)
Standard Specification for Metal Injection Molded Cobalt-28Chromium-6Molybdenum Components for Surgical Implant Applications

ABSTRACT
This specification covers chemical, mechanical, and metallurgical general requirements for metal injection molded (MIM) cobalt-28chromium-6molybddenum components to be used in manufacturing surgical implants. In this specification, the MIM components covered may have been densified beyond their as-sintered density by post-sinter processing. For the chemical requirements, the components supplied in this specification must conform in accordance to the chemical requirements specified herein in Table 1. The product analysis tolerances must also conform to the product tolerances presented in Table 2. The specification also enumerates the mechanical requirements for MIM components wherein the tensile properties of the MIM must conform to the mechanical properties in Table 3. The microstructural requirements and specimen preparation shall be in accordance with Guide E3 and Practice E407.
SCOPE
1.1 This specification covers chemical, mechanical, and metallurgical requirements for metal injection molded (MIM) cobalt-28chromium-6molybdenum components to be used in the manufacture of surgical implants  
1.2 The MIM components covered by this specification may have been densified beyond their as-sintered density by post-sinter processing.  
1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A480/A480M-23a(Specification)
Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip

ABSTRACT
This specification covers general requirements for flat-rolled stainless and heat-resisting steel plate, sheet, and strip. The steel shall be made by one of the following processes: electric-arc, electric-induction, or other suitable processes. Heat and product analyses shall conform to the chemical requirements for each of the specific elements. The material shall undergo mechanical tests such as tension test, hardness test, and bend test. Special tests like intergranular corrosion test, permeability test, Charpy impact testing and tests for detrimental intermetallic phases in wrought duplex stainless steels shall be also be performed when required.
SCOPE
1.1 This specification2 covers a group of general requirements that, unless otherwise specified in the purchase order or in an individual specification, shall apply to rolled steel plate, sheet, and strip, under each of the following specifications issued by ASTM: Specifications A240/A240M, A263, A264, A265, A666, A693, A793, and A895.  
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The SI units are shown in brackets, except that when A480M is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished in inch-pound units.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
