Adityvioji gamyba. Neardomieji bandymai ir įvertinimas. Matmenų nustatymo kūginio pluošto kompiuterine rentgeno tomografija gairės (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.

Komentavimo iki data 2026-07-23

Modernioji techninė keramika. Monolitinės keramikos termomechaninės savybės. 5 dalis. Tampros modulių nustatymas aukštoje temperatūroje

This part of EN 820 describes methods for determining the elastic moduli, specifically Young's modulus, shear modulus and Poisson's ratio, of advanced monolithic technical ceramics at temperatures above room temperature. The standard prescribes three alternative methods for determining some or all of these three parameters: A the determination of Young's modulus by static flexure of a thin beam in three- or four-point bending. B the determination of Young's modulus by forced longitudinal resonance, or Young's modulus, shear modulus and Poisson's ratio by forced flexural and torsional resonance, of a thin beam. C the determination of Young's modulus from the fundamental natural frequency of a struck bar (impulse excitation method). This part of EN 820 extends the above-defined room-temperature methods described in EN 843-2 to elevated temperatures. All the test methods assume the use of homogeneous test pieces of linear elastic materials. The test assumes that the test piece has isotropic elastic properties. At high porosity levels all of the methods can become inappropriate. The maximum grain size (see EN 623-3), excluding deliberately added whiskers, should be less than 10 % of the minimum dimension of the test piece. NOTE 1 Method C in EN 843-2 based on ultrasonic time of flight measurement has not been incorporated into this part of EN 820. Although the method is feasible to apply, it is specialised, and outside the capabilities of most laboratories. There are also severe restrictions on test piece geometries and methods of achieving pulse transmission. For these reasons this method has not been included in EN 820-5. NOTE 2 The upper temperature limit for this test depends on the properties of the test pieces, and can be limited by softening within the timescale of the test. In addition, for method A there can be limits defined by the choice of test jig construction materials.

Reikalavimai, keliami lygiagrečiai prie skirstomųjų tinklų jungiamoms elektrinėms. 10 dalis. Elektros energijos gamybos blokų atitikties vertinimo bandymai

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.
