Standard Practice for Reporting Data for Test Specimens Prepared by Additive Manufacturing

Standard Practice for Reporting Data for Test Specimens Prepared by Additive Manufacturing

SIGNIFICANCE AND USE
4.1 Due to variables unique to each AM process and piece of equipment, it is critical to standardize descriptions used to report the preparation, processing, and post processing of specimens produced for tests or evaluation. The intent of this practice is to consistently document the materials and processing history associated with specimens undergoing test or evaluation. The level of detail for the documentation will match the application.  
4.2 This practice establishes minimum data element requirements for reporting of material and process data for the purpose of:  
4.2.1 Standardizing test specimen descriptions and test reports,  
4.2.2 Assisting designers by standardizing AM materials databases,  
4.2.3 Aiding material traceability through testing and evaluation,  
4.2.4 Capturing property-parameter-performance relationships of AM specimens to enable predictive modeling and other computational approaches.
SCOPE
1.1 This practice describes a standard procedure for reporting results by testing or evaluation of specimens produced by additive manufacturing (AM). This practice provides a common format for presenting data for AM specimens, for two purposes: (1) to establish further data reporting requirements, and (2) to provide information for the design of material property databases.  
1.2 The values stated in SI units are required for all additive manufacturing related standards. However, when this standard is used in combination with any test method or equipment specified in inch-pound units the results should be reported with mathematical conversions to SI units immediately following in parentheses. The conversions shall be provided for information only and are not considered 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 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...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications.

ASTM D5141-23(Test Method)
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 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.

Standard Guide for Assessing the Environmental and Human Health Impacts of New Compounds for Military Use

SIGNIFICANCE AND USE
5.1 The purpose of this guide is to provide a logical, tiered approach in the development of environmental health criteria coincident with level and effort in the research, development, testing, and evaluation of new materials for military use. Various levels of uncertainty are associated with data collected from previous stages. Following the recommendation in the guide should reduce the relative uncertainty of the data collected at each developmental stage. At each stage, a general weight of evidence qualifier shall accompany each exposure/effect relationship. They may be simple (for example, low, medium, or high confidence) or sophisticated using a numerical value for each predictor as a multiplier to ascertain relative confidence in each step of risk characterization. The specific method used will depend on the stage of development, quantity and availability of data, variation in the measurement, and general knowledge of the dataset. Since specific formulations, conditions, and use scenarios may not be known until the later stages, exposure estimates can be determined when practical (for example, Engineering and Manufacturing Development; see 6.6). Exposure data can then be used with other toxicological data collected from previous stages in a quantitative risk assessment to determine the relative degree of hazard.  
5.2 Data developed from the use of this guide are designed to be consistent with criteria required in weapons and weapons system development (for example, programmatic environment, safety and occupational health evaluations, environmental assessments/environmental impact statements, toxicity clearances, and technical data sheets).  
5.3 Information shall be evaluated in a flexible manner consistent with the needs of the authorizing program. This requires proper characterization of the current problem. For example, compounds may be ranked relative to the environmental criteria of the prospective alternatives, the replacement compound, and within bo...
SCOPE
1.1 This guide is intended to determine the relative environmental influence of new substances, consistent with the research and development (R&D) level of effort and is intended to be applied in a logical, tiered manner that parallels both the available funding and the stage of research, development, testing, and evaluation. Specifically, conservative assumptions, relationships, and models are recommended early in the research stage, and as the technology is matured, empirical data will be developed and used. Munition constituents are included and may include propellants, oxidizers, explosives, binders, stabilizers, metals, dyes, and other compounds used in the formulation to produce a desired effect. Munition systems range from projectiles, grenades, rockets/missiles, training simulators, to smokes and obscurants. Given the complexity of issues involved in the assessment of environmental fate and effects and the diversity of the systems used, this guide is broad in scope and not intended to address every factor that may be important in an environmental context. Rather, it is intended to reduce uncertainty at minimal cost by considering the most important factors related to human health and environmental impacts of energetic materials. This guide provides an outline for collecting data useful in a relative ranking procedure to provide the systems scientist with a sound basis for prospectively determining a selection of candidates based on environmental and human health criteria. The general principles in this guide are applicable to substances other than energetics if intended to be used in a similar manner with similar exposure profiles.  
1.2 The scope of this guide includes:  
1.2.1 Energetic and other new/novel materials and compositions in all stages of research, development, test and evaluation.  
1.2.2 Environmental assessment, including:
1.2.2.1 Human and ecological effects of the unexploded energetics and ...

Test Method for Shrinkage Temperature of Wet Blue and Wet White

SIGNIFICANCE AND USE
5.1 This test method is designed to determine the temperature at which the Wet Blue or Wet White specimen experiences shrinkage. In this test method, shrinkage occurs as a result of hydrothermal denaturation of the collagen protein molecules which make up the fiber structure of the Wet Blue or Wet White. The shrinkage temperature of Wet Blue or Wet White is influenced by many different factors, most of which appear to affect the number and nature of crosslinking interactions between adjacent polypeptide chains of the collagen protein molecules. The value of the shrinkage temperature of Wet Blue or Wet White is commonly used as an indicator of the type of tannage or the degree of tannage, or both, of that particular Wet Blue or Wet White (especially for the more hydrothermally stable tannages such as chrome tannage).
SCOPE
1.1 This test method covers the determination of the shrinkage temperature of all types of Wet Blue and Wet White. The heating medium is water when the shrinkage temperature is at or below 98 °C. The heating medium is a glycerine-water solution when the shrinkage temperature is above 98 °C.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
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.

Standard Guide for the Selection and Use of Waterstops

SIGNIFICANCE AND USE
4.1 This guide is intended to be used in the selection and installation of waterstops in cast-in-place concrete construction. This guide is intended to assist the building owner, owner’s representative, architect, engineer, contractor, and/or authorized inspector during the specification and installation of waterstops.  
4.2 This guide is applicable to cast-in-place concrete construction. The use of this guide may not be appropriate for installation of waterstops in other types of concrete construction, including but not limited to, pneumatically applied (that is, shotcrete) and precast concrete construction.
SCOPE
1.1 This guide covers the use of waterstops within cast-in-place concrete construction. Waterstops are generally placed within static, non-moving construction joints in concrete to close off the joint to water, which may be under significant hydrostatic pressure. They are used as part of the overall waterproofing strategy for a building or other structure. Expansion and other types of moving joints may require the use of waterstops, which can accommodate the anticipated movement of the structure and are beyond the scope of this guide.  
1.2 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.  
1.3 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.

Standard Guide for Monitoring the Neutron Exposure of LWR Reactor Pressure Vessels

SIGNIFICANCE AND USE
4.1 Regulatory Requirements—The USA Code of Federal Regulations (10CFR Part 50, Appendix H) requires the implementation of a reactor vessel materials surveillance program for all operating LWRs. Other countries have similar regulations. The purpose of the program is to (1) monitor changes in the fracture toughness properties of ferritic materials in the reactor vessel beltline6 resulting from exposure to neutron irradiation and the thermal environment, and (2) make use of the data obtained from surveillance programs to determine the conditions under which the vessel can be operated with adequate margins of safety throughout its service life. Practice E185, derived mechanical property data, and (r, θ, z) physics-dosimetry data (derived from the calculations and reactor cavity and surveillance capsule measurements (1) using physics-dosimetry standards) can be used together with information in Guide E900 and Refs. 4, 11-18 to provide a relation between property degradation and neutron exposure, commonly called a “trend curve.” To obtain this trend curve at all points in the pressure vessel wall requires that the selected trend curve be used together with the appropriate (r, θ, z) neutron field information derived by use of this guide to accomplish the necessary interpolations and extrapolations in space and time.  
4.2 Neutron Field Characterization—The tasks required to satisfy the second part of the objective of 4.1 are complex and are summarized in Practice E853. In doing this, it is necessary to describe the neutron field at selected (r, θ, z) points within the pressure vessel wall. The description can be either time dependent or time averaged over the reactor service period of interest. This description can best be obtained by combining neutron transport calculations with plant measurements such as reactor cavity (ex-vessel) and surveillance capsule or RPV cladding (in-vessel) measurements, benchmark irradiations of dosimeter sensor materials, and knowledge of th...
SCOPE
1.1 This guide establishes the means and frequency of monitoring the neutron exposure of the LWR reactor pressure vessel throughout its operating life.  
1.2 The physics-dosimetry relationships determined from this guide may be used to estimate reactor pressure vessel damage through the application of Practice E693 and Guide E900, using fast neutron fluence (E > 1.0 MeV and E > 0.1 MeV), displacements per atom (dpa), or damage-function-correlated exposure parameters as independent exposure variables. Supporting the application of these standards are the E853, E944, E1005, and E1018 standards, identified in 2.1.  
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.
