This document provides the methods, parameter sets and models to develop and utilize a data package for a part created using AM technologies (AM part). This document is scoped to the information requirements associated with workflow of the fabrication of an AM part, from design to acceptance. Peripheral information related to entities such as organization, facility, operator, security, and others is addressed for sake of completeness; but is not the focus of this document and can be defined elsewhere. This document provides the means to develop an organizational or application-specific data package for the communication between and amongst the designer, the manufacturer, and all acceptance authorities, among other potential stakeholders. This document does not impose a plan of execution to produce an AM part, though a digital thread is provided to establish a referenceable information workflow. The requirements set forth in this document are based on the fabrication of a part using the PBF-LB/M process. While specific details directly relate to PBF-LB/M, generalized workflow requirements can be related to any AM process.

This document specifies the method for the calibration of hand torque tools and describes the method of calculation of measurement uncertainties for the calibration. It also specifies the minimum requirements for a certificate of calibration to this standard for hand torque tools. The Annex C of this document specifies the minimum requirements for the calibration of the torque measurement device where the relative measurement uncertainty interval, W´md, is not already provided by a traceable calibration certificate. This document applies to hand torque tools which are classified as indicating torque tools (Type I) and setting torque tools (Type II). NOTE  Hand torque tools covered by this document are those identified in ISO 1703:2018 by reference numbers 7 1 00 01 0 to 7 1 00 14 0 inclusive. Torque limiting hand torque tools do not yet have reference numbers and will not do so until the next revision of ISO 1703

This document covers additively manufactured stainless steel components using full-melt powder bed fusion such as electron beam melting and laser melting. The components produced by these processes are used typically in applications that require mechanical properties similar to machined forgings and wrought products. Components manufactured to this specification are often, but not necessarily, post processed via machining, grinding, electrical discharge machining (EDM), polishing, and so forth to achieve desired surface finish and critical dimensions. This document is intended for the use of mechanical engineers to size equipment, purchasers or producers, of additively manufactured components for defining the requirements and ensuring component properties. This document 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 document to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This standard specifies the characterization of ceramic slurry for use as feedstock in vat photopolymerization additive manufacturing (AM) process. The characterization includes the composition and properties of the slurry, such as solids content, dynamic viscosity, particle size distribution, chemical composition, and solid dispersion stability. This standard also provides available methods about sampling and preparing slurry samples for testing. This standard does not deal with safety aspects.

This document specifies a classification of the imperfections likely to be generated during an additive manufacturing operation by PBF-LB (laser beam powder bed fusion) or PBF-EB (electron beam powder bed fusion) for metal parts. This document also indicates the most probable causes of the formation of imperfections and gives some illustrations taken from feedback. NOTE This classification applies to both PBF-LB and PBF-EB processes and can be extended to other additive manufacturing processes.

This document specifies the dimensions, the method of sampling and the preparation of the test specimens, also the conditions for performing the low temperature tensile test perpendicular to the weld in order to determine the low temperature tensile welding factor. A low temperature tensile test can be used in conjunction with other tests (e.g. bend, tensile creep, macro) to assess the performance of welded assemblies, made from thermoplastics materials. The low temperature tensile welding factor and the appearance of the fracture surface provide a guide regarding the ductility of the joint and the quality of the work. The test is applicable to co-axial or co-planar welded assemblies made from thermoplastics materials filled or unfilled, but not reinforced, irrespective of the welding process used. The test is not applicable for co-axial welded assemblies of an external diameter less than 20 mm.
