Additive manufacturing - Non-destructive testing and evaluation - Guideline for dimensional measurements based on cone beam X-ray Computed Tomography (ISO/ASTM DIS 52971:2026)

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.

Qualification testing of welders - Fusion welding (ISO/DIS 9606:2026)

This document specifies the requirements for qualification testing of welders for fusion welding of steels, aluminium, copper, nickel, titanium and zirconium. In this document, the terms "aluminium", “copper”, “nickel”, “titanium” and “zirconium” refer to the materials and their alloys. This document provides a set of technical rules for a systematic qualification test of the welder, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner or examining body. When qualifying welders, the emphasis is placed on the welder's ability to manually manipulate the electrode, welding torch or welding blowpipe, thereby producing a weld of acceptable quality. The fusion welding processes referred to in this document include welding processes which are designated as manual or partly mechanized. This document does not cover fully mechanized and automated welding processes which are covered by ISO 14732. The principles of this document can be applied to other fusion welding processes.

Measurement of radioactivity - Gamma ray and beta emitting radionuclides - Test method to assess the ease of decontamination of surface materials (ISO 8690:2024)

This document applies to the testing of surfaces that may become contaminated by radioactive materials. The ease of decontamination is a property of a surface and an important criterion for selecting surface materials used in the nuclear industry, interim storage or disposal facilities from which contamination can be removed easily and rapidly without damaging the surface. The test described in this document is a rapid laboratory-based method to compare the ease of decontamination of different surface materials. The results from the test can be one parameter to take into account when selecting surface coatings such as varnish or impervious layers such as ceramics and other surfaces. The radionuclides used in this test are those commonly found in the nuclear industry (137Cs, 134Cs and 60Co) in aqueous form. The test can also be adopted for use with other radionuclides and other chemical forms, depending on the customer requirements, if the solutions are chemically stable and do not corrode the test specimen. The test does not measure the ease of decontamination of the surface materials in practical use, as this depends on the radionuclide(s) present, their chemical form, the duration of exposure to the contaminant and the environmental conditions amongst other factors. The test method is not intended to describe general decontamination procedures or to assess the efficiency of decontamination procedures (see ISO 7503-1 to ISO 7503-3). The test method is not suitable for use of radiochemicals if the radionuclide emits low energy gamma rays or beta particles that are readily attenuated in the surface.

Requirements for generating plants to be connected in parallel with distribution networks - Part 10: Tests for conformity assessment of generating units

The purpose of this document is to provide technical guidance for tests on generating units, interface protection and generating plant controller to evaluate their electrical characteristics. NOTE 1 Mechanical issues are taken into account as far as they influence the electrical characteristics. NOTE 2 Electrical energy storage systems (EESS) in meeting the conditions of 50549-1 and 50549-2 are considered as generating units. The evaluation results are intended to be used to demonstrate conformity of generating units, interface protection and generating plant controller to technical requirements for grid connection. In this context the evaluation results can also be used as part of a certification programme. NOTE 3 Besides the type test results of the generating units, interface protection and generating plant controller all additional elements for connection to the grid (e.g. transformer, cabling, multiple units) are considered in the evaluation of the final installation of a generating plant. The requirements intended to be evaluated are covered in the following standardization documents: - EN 50549-1:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 1: connection to a LV distribution network - Generating plants up to and including Type B - EN 50549-2:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 2: Connection to a MV distribution network - Generating plants up to and including Type B If grid connection requirements are dealt with in other documents or for other generating module types, where no specific testing procedure is provided, the testing methods described in this document can be used, if applicable. This document provides evaluation criteria for the conformity assessment of generating units with respect to the above mentioned standardization documents, based on type testing. However, some requirements are applicable on the generating plant level. The assessment of the conformity to these plant requirements is out of scope of this document. Nevertheless, this document can be used to show the capabilities of a generating unit to be used in a generating plant. As a consequence, it is possible that the conformity assessment of a generating unit does not cover all aspects of the above mentioned standardization documents, typically when a requirement is evaluated on plant level. Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and which clauses are not covered. This document recognizes the existence of specific technical test requirements within several member states and these must be complied with.
