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.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.

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.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.

4.1 CTM must be properly manufactured in a manner consistent with a minimum level of quality control as determined by in-house testing of the final product. This practice suggest types of tests, the methods of the testing and the minimum testing frequencies.4.2 It should be clearly recognized that manufacturers may perform additional tests or at a greater frequency than required in this practice, or both. In this case the manufacturer’s quality control plan will take precedence over this practice. The quoted tests and test methods in Table 1 must appear in the QC plan and QC report.4.3 It should also be recognized that purchasers and installers of CTM may require additional tests or a greater frequency than called for in this practice or both. The organization(s) producing such project specific specification or quality assurance plan should recognize that such requirements are beyond the current state of the practice. If such a request is made by the purchasers or installers, they should clearly communicate the requirements to the manufacturer or supplier during the contract decisions in order that disputes do not arise at a subsequent time.4.4 This practice provides a means by which samples of CTM may be selected to provide a statistically valid sample for selection of test specimens without previous knowledge of the variability that may exist between production units.4.5 The principles stated in Practice D4271, and the illustrative text in that practice can be used by the test method authors in preparing sampling statements.1.1 This practice covers the manufacturing quality control of Consumer Trampoline-Bed Material (CTM), describing types of tests, the proper test methods, minimum testing frequencies, and best practices for sampling.1.2 This practice is intended to aid manufacturers, suppliers, purchasers, installers, and end users of CTM in establishing a minimum level of effort for maintaining quality control.1.3 This practice does not address manufacturing quality assurance, product acceptance testing, or conformance testing. These are independent activities taken by organizations other than the CTM manufacturer.1.4 This practice covers procedures for sampling CTM for the purpose of manufacturing quality control (MQC). These procedures are designed to ensure the correct number of representative samples are obtained and properly reported by the manufacturer.1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
