ASTM F3560-22(Specification)
Standard Specification for Additive Manufacturing – Data – Common Exchange Format for Particle Size Analysis by Light Scattering

SCOPE
1.1 This specification has been developed to facilitate exchanging and analyzing particle size distribution (PSD) by light scattering data from databases, data management systems, point of origin, or other data sources that may use different data dictionaries, schemas, or formats.  
1.2 This specification prescribes the use of a common exchange format in such a way that PSD data defined through proprietary means can be easily exchanged for process understanding and qualification.  
1.3 This specification facilitates the interoperability of PSD data by identifying the data elements defined in standardized terminology, as well as defining those salient terms with indisputable meanings. In doing so, this specification extends the common AM data dictionary defined in Practice F3490 to encapsulate PSD process-specific data elements. Generic data elements and relationships present in that standard are inherited and applied in this practice where relevant.  
1.4 This specification specifies names that serve to uniquely identify the PSD data elements. The data type, value domain, and term definition for each data element are also specified in this practice. References are provided for those data elements with established definitions or reporting guidelines in existing standards.  
1.5 This specification prescribes a file format and structure for the exchange of PSD data. This format defines a method for sharing data via the defined PSD data elements herein and provides a basis for validation of data exchanged using this format.  
1.6 This specification recommends levels of data sharing that vary from minimal to robust. It prescribes best practices for checking conformance based on the common data exchange format.  
1.7 This specification does not specify:  
1.7.1 An exhaustive set of data items that could be exchanged related to PSD by light scattering.  
1.7.2 A definition of a minimum viable data set for PSD by light scattering.  
1.7.3 Data items or an exchange format for PSD methods other than light scattering, for example, imaging or sieving.  
1.7.4 Data elements for data modules related to PSD (for example, for personnel, material, or equipment).  
1.7.5 The implementation details of how data should be imported to proprietary data management systems from the common data exchange format.  
1.7.6 The implementation details of how data should be exported from proprietary data management systems to the common data exchange format.  
1.7.7 Guidelines for creating unique identifiers for data module records  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 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 Practice for Implementing Communications Impairments on A-UGV Systems

SIGNIFICANCE AND USE
4.1 A-UGVs operate in a wide range of indoor and outdoor applications that include many communications challenges that can affect A-UGV control and monitoring. An A-UGV system or A-UGVS as defined in Terminology F3200 includes the A-UGV and all associated components, equipment, software, and communications necessary to make a fully functional system. Communications impairments can cause: (1) changes in A-UGV operation, (2) changes in behavior in system components such as control and scheduling, or (3) changes in operation or timing of infrastructure equipment coordination. This practice is intended to record the task performance of an A-UGV while communications are impaired in a specified and repeatable manner (for example, standard test method).  
4.2 Communications impairments can occur at a variety of locations within the A-UGVS. The network topology in Fig. 1 shows many of the common communications links that could be impaired. The numbered arrows in Fig. 1 label different places where communications impairments could occur. The box colors (that is, green, red, blue) indicate different types of impairments where the two red boxes are similar to each other. Fig. 1 will be used throughout this practice and included on the test report for use in describing the test setup and results by the test supervisor.  
FIG. 1 Block Diagram of Communications for Control/Monitoring of A-UGVs and Associated Facility Equipment in which Numbers with Arrows Indicate Examples of Communications Impairment Locations  
4.3 The requested expected results provide pass/fail reporting criteria along with recorded notes pertinent to the test or results or both. It is possible that the communications impairments used will have no noticeable effect, and this is often the desired outcome.
SCOPE
1.1 This practice considers impairments of communications within an automatic, automated, or autonomous unmanned ground vehicle (A­UGV) system during task execution. An A-UGV system typically uses communications between an A-UGV and fixed system components and resources, such as off-board control, job and fleet scheduling, infrastructure equipment interactions, or cloud-computing programs for tasks. Communications impairments can cause an A-UGV operation to change in various ways that can include delays or failure to complete the task.  
1.2 This practice is designed for applying known communications impairments to an A-UGV system in conjunction with A-UGV task testing. It is designed to create similar changes in communications that can possibly cause task performance limiting effects that are often experienced by an A-UGV system in different environments.  
1.3 This practice is intended to simulate impairments that may be present during the operation of an A-UGV system. This practice can be used, for example, by a manufacturer to indicate that system performance was tested to be robust against specific test communications impairments. The tests are not intended to test situations that should be eliminated during system installation, for example, a duplicate internet protocol (IP) address on the network.  
1.4 This practice only describes communications impairments. It does not specify an A-UGV task. The A-UGV task should be a defined ASTM International test method or task description in similar detail.  
1.5 This practice defines methods to record communications impairment types and extents while the A-UGV is stationary or performs a task. Temporal or spatial extents in which communications impairments occur include the timing, duration, location within the task, or other triggered events. Examples for implementing common communications impairments are provided.  
1.6 This practice is not intended for:  
1.6.1 Communications impairments between onboard components of an A-UGV, for example, onboard sensors-to-onboard computers.  
1.6.2 Communications or measurement impairments directly affecting external reference or p...

The testing results of the candidate A-UGV shall describe, in a statistically significant way, the ability of the A-UGV to position itself at a fixed location or relative to a dock. This test method defines tests for use by manufacturers and users of A-UGVs to measure and record the docking performance. The test applies to different types of A-UGV, applications and test apparatus.  
7.2 Navigation—The test applies to all types of navigation. The capabilities of the A-UGV to apply its navigation method to a given environment will be objectively determined by its performance in the test.  
7.3 Vehicle—The test results of the candidate A-UGV will confirm, in a statistically significant way, how reliably an A-UGV arrives at a dock from one or more start locations. Refer to Test Method F3244 for typical vehicle configurations.  
7.4 Apparatus—The test method is scalable, using similar apparatus to interface to different A-UGVs.  
7.5 Defining a Successful Test—The probability that a repetition will be successful (R) and the confidence (C) in that probability are used to identify how many sequential successful repetitions are required to pass a test. The test requestor shall define these values and record them on the test report (see Appendix X1 Table X1.1).
SCOPE
1.1 This test method defines standard tests that demonstrate and confirm positioning of an A-UGV. Positioning, the repeatability of A-UGV location when stationary after completing maneuvers to a stop location, may be defined globally or locally relative to local infrastructure. The latter has become known as docking. See Terminology F3200-18a for terminology definitions. The test also includes a method to confirm the repeatability of height control of load transfer equipment, for example an A-UGV with fork tines.  
1.2 This test method is intended for use by A-UGV manufacturers, installers, and users to quantitatively confirm the maneuverability and repeatability of an A-UGV’s positioning or docking. Positioning and docking are similar operations and the tests described are applicable to either. The term docking will be used throughout this test method to include both global positioning and local docking. The tests facilitate comparative trials across a set of A-UGVs or multiple trials over a period of time.  
1.3 The tests can be carried out by many vehicles using different methods of location measurement and control to achieve the demanded performance. Vehicle configurations and vehicle components include:  
1.3.1 Vehicle load type (for example, fork lift, roller deck, trailer, flat deck);  
1.3.2 Vehicle drive mechanics (for example, steered tricycle, two-wheel differential, steered omni-directional or ‘mecanum wheel’ drives);  
1.3.3 Navigation sensors (for example, scanning laser, local beacons, floor marking, environmental features);  
1.3.4 Docking sensors (sensors, for example, camera, line detector, and laser scanner, which are used primarily for local measurement at the dock).  
1.4 The A-UGV may include roller tables, fork tines, robot arm(s) or other mechanisms to transfer the load or interact with the dock (for example, perform assembly). The standard test can be applied to A-UGVs with any of these load transfer mechanisms. The repeatability along each measured axis is measured and compared to a defined repeatability margin. The set of repeatability margins comprises the complete task performance margin (TPM).  
1.5 This test method shall be performed in a testing laboratory or the location where the specified apparatus and environmental conditions are implemented. Environmental conditions shall be recorded as specified in Practice F3218-17.  
1.6 Standard test apparatus is specified to be easily fabricated, facilitating self-evaluation by A-UGV developers and users, and providing practice for A-UGV developers, u...

Standard Guide for Formats for Collection and Compilation of Corrosion Data for Metals for Computerized Database Input

SIGNIFICANCE AND USE
4.1 The guide is intended to facilitate the recording of corrosion test results and does not imply or endorse any particular database design or schema. It provides a useful reference to be consulted before initiating a corrosion test to be sure plans are made to record all relevant data.  
4.2 Corrosion tests are usually performed following a prescribed test procedure that is often not a standard test method. Most corrosion tests involve concurrent exposure of multiple specimens of one or more materials (refer to 6.1.1).  
4.3 This guide is designed to record data for individual specimens with groupings by separate tests (as contrasted to separate test methods) as described in 4.2 and 6.1.1. Consequently, some of the individual fields may apply to all of the specimens in a single test, while others must be repeated as often as necessary to record data for individual specimens.  
4.4 The guidelines provided are designed for recording data for entry into computerized material performance databases. They may be useful for other applications where systematic recording of corrosion data is desired.  
4.5 Reliable comparisons of corrosion data from multiple sources will be expedited if data are provided for as many of the listed fields as possible. Comparisons are possible where data are limited, but some degree of uncertainty will be present.  
4.6 Certain specialized corrosion tests may require additional data elements to fully characterize the data recorded. This guide does not preclude these additions. Other ASTM guides for recording data from mechanical property tests may be helpful.  
4.7 This guide does not cover the recording of data from electrochemical corrosion tests.  
4.8 These material identification guidelines are compatible with Guide E1338.
SCOPE
1.1 This guide covers the data categories and specific data elements (fields) considered necessary to accommodate desired search strategies and reliable data comparisons in computerized corrosion databases. The data entries are designed to accommodate data relative to the basic forms of corrosion and to serve as guides for structuring multiple source database compilations capable of assessing compatibility of metals and alloys for a wide range of environments and exposure conditions.  
1.2 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 Application of ASTM Evaluated Cross Section Data File

SIGNIFICANCE AND USE
4.1 The ENDF/B library in the United States and similar libraries elsewhere, such as JEFF (23), JENDL (21), and BROND (22), provide a compilation of neutron cross section and other nuclear data for use by the nuclear community. The availability of these excellent evaluations makes possible standardized usage, thereby allowing easy referencing and intercomparisons of calculations. However, as the first ENDF/B files were developed it became apparent that they were not adequate for all applications. This need resulted in the development of the specialized ENDF/B Dosimetry File (17, 25), consisting of activation cross sections important for dosimetry applications. This file was made available worldwide. Later, other “Special Purpose” files were introduced (26). In the ENDF/B-VI compilation (27), dosimetry files no longer appeared as separate evaluation files. The ENDF/B-VII.0 compilation (28) removed most of the reaction-specific covariance files used by the dosimetry community. It kept the covariance files for the “standard cross sections” in a special sub-library, but the covariance data in this sub-library are only provided over the energy range in which each reaction is considered to be a “standard”, and does not include the full energy range required for LWR PVS dosimetry applications. Later updates to the ENDF/B releases added covariance files for some reaction channels but these covariance files were often based solely on calculations and were not representative of the methodology used to derive the underlying ENDF/B cross section. In response to the need for a dosimetry-specific library, the International Atomic Energy Agency convened a Coordinated Research Project (CRP) that drew upon the set of international experts to provide a recommended set of dosimetry cross sections and to compile a set of validation evidence that supported the use of this recommended dataset. This file, the International Reactor Dosimetry and Fusion File (IRDFF) (19, 20), draws upon oth...
SCOPE
1.1 This guide covers the establishment and use of an ASTM evaluated nuclear data cross section and uncertainty file for analysis of single or multiple sensor measurements in neutron fields related to light water reactor LWR-Pressure Vessel Surveillance (PVS). These fields include in- and ex-vessel surveillance positions in operating power reactors, benchmark fields, and reactor test regions.  
1.2 Requirements for establishment of ASTM-recommended cross section files address data format, evaluation requirements, validation in benchmark fields, evaluation of error estimates (covariance file), and documentation. A further requirement for components of the ASTM-recommended cross section file is their internal consistency when combined with sensor measurements and used to determine a neutron spectrum.  
1.3 Specifications for use include energy region of applicability, data processing requirements, and application of uncertainties.  
1.4 This guide is directly related to and should be used primarily in conjunction with Guides E482 and E944, and Practices E560, E185, and E693.  
1.5 The ASTM cross section and uncertainty file represents a generally available data set for use in sensor set analysis. However, the availability of this data set does not preclude the use of other validated data, either proprietary or nonproprietary. When alternate cross section files that deviate from the requirements laid out in this standard are used, the deviations should be noted to the customer of the dosimetry application.  
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 standar...

ASTM ISO/ASTM52921-13(2019)(Terminology)
Standard Terminology for Additive Manufacturing—Coordinate Systems and Test Methodologies

SIGNIFICANCE AND USE
3.1 Although many additive manufacturing systems are based heavily upon the principles of Computer Numerical Control (CNC), the coordinate systems and nomenclature specific to CNC are not sufficient to be applicable across the full spectrum of additive manufacturing equipment. This terminology expands upon the principles of ISO 841 and applies them specifically to additive manufacturing. Although this terminology is intended to complement ISO 841, if there should arise any conflict, this terminology shall have priority for additive manufacturing applications. For any issues not covered in this terminology, the principles in ISO 841 may be applied.  
3.2 Furthermore, this terminology does not prescribe the use of any specific existing testing methodologies or standards that practitioners of AM may wish to employ for testing purposes; however, it is expected that practitioners will employ appropriate existing methodologies and standards to test parts made by AM.
SCOPE
1.1 This terminology includes terms, definitions of terms, descriptions of terms, nomenclature, and acronyms associated with coordinate systems and testing methodologies for additive manufacturing (AM) technologies in an effort to standardize terminology used by AM users, producers, researchers, educators, press/media, and others, particularly when reporting results from testing of parts made on AM systems. Terms included cover definitions for machines/systems and their coordinate systems plus the location and orientation of parts. It is intended, where possible, to be compliant with ISO 841 and to clarify the specific adaptation of those principles to additive manufacturing.
Note 1: The applicability of this standard to cladding has to be evaluated. Discussions are under progress.
Note 2: Non-cartesian systems are not covered by this standard.  
1.2 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.  
1.3 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.
