This document defines the rules to be applied for symbolic representation of welded joints on technical drawings. This can include information about the geometry, manufacture, quality and testing of the welds. The principles of this document can also be applied to soldered and brazed joints. It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In this document: — clauses, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line; — clauses, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line; — clauses, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems. The symbols shown in this document can be combined with other symbols used on technical drawings, for example to show surface finish requirements. An alternative designation method is presented which can be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements. NOTE Examples given in this document, including dimensions, are illustrative only and are intended to demonstrate the proper application of principles.

This document specifies guidelines and recommendations to be followed prior to carrying out dimensional measurements on three-dimensional (3D) volumetric X-ray Computed Tomographic (XCT) images of additive manufacturing (AM) series production parts. It is applicable to cone beam XCT systems. However, these guidelines and recommendations can easily be transposed to fan beam XCT systems. The process to be followed prior to performing dimensional measurement on 3D volumetric XCT images of AM series production parts, in this standard, is divided into two steps: Step 1: Quantification of an XCT system performance, in terms of image quality and basic dimensional measurement accuracy, with a reference object and eventually a Representative Quality Indicators (RQI), with the specific part (part chosen from the AM series production parts) XCT setting under certain environmental conditions. This step leads to the determination of the image quality, the voxel size and the basic dimensional measurement accuracy of an XCT system; Step 2: Validation of the XCT system compliance, in terms of dimensional measurement accuracy, with the specific part, with the chosen XCT setting under the specific environmental conditions. This step leads to a simplified determination of the dimensional measurement uncertainty of each measurand of the specific part. If step 1 does not comply with the set requirements, the XCT system cannot be used for step 2. This document does not claim to provide a definitive method to determine XCT dimensional measurement accuracy, which, given the complexity of an XCT process, is not yet established. For the same reason, it is addressed to qualified XCT operators with the support of metrology experts. This document is dedicated to AM series production parts and its aim is to provide a methodology for controlling the geometric specificities associated with AM (internal shapes, lattice structures). It is applicable on parts that are fabricated by any type of AM categories of processes and material provided the X-ray penetration lengths are sufficient to scan the test part. These prior quantification and validation processes, which allow dimensional measurements to be carry out on 3D volumetric XCT images of AM series production parts, are valid for a specific part geometry in a given material associated with a chosen XCT setting (magnification & XCT acquisition and reconstruction parameters of the specific part) under specific environmental conditions for the measurands specified. The quantification and validation processes are reconsidered when different geometry of the part or material or XCT setting or environmental conditions or measurands are taken into account.

This International Standard specifies requirements for determining commutability of a CRM (3.4)for which commutability (3.7) with clinical samples (3.6) is required, and the content of the supporting documentation. This standard is applicable to a commutable (3.7) CRM (3.4) intended for use as a secondary calibrator (3.32) or international conventional calibrator (3.13) in the m.3 position of calibration hierarchies described in ISO 17511 and that comply with the requirements of ISO 15194. This Standard is also applicable to a CRM (3.4) used as a trueness control (3.33) for an end-user measurement procedure (MP) (3.19). This standard applies primarily to commutable secondary calibrator (3.32) CRMs (3.4) with assigned property values where the property has a magnitude that can be expressed as a quantitative scalar number or ratio to a reference or refers to a counting scale as also described in the scope of ISO 17511. For qualitative or visually interpreted measurement procedures, this document may serve as a conceptual framework, but additional criteria may apply. When a commutable secondary calibrator (3.32) CRM (3.4) includes multiple measurands, this Standard is applied to each of the measurands present in the CRM (3.4). This standard does not apply to a primary reference material (3.25) that consists of a defined high-purity analyte (3.1).
