Water quality - Gross alpha and gross beta activity - Test method using thin source deposit (ISO/DIS 10704:2026)

This document specifies a method for the determination of gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides. Gross alpha and gross beta activity measurement is not intended to give an absolute determination of the activity concentration of all alpha and beta emitting radionuclides in a test sample, but is a screening analysis to ensure particular reference levels of specific alpha and beta emitters have not been exceeded. This type of determination is also known as gross alpha and gross beta index. Gross alpha and gross beta analysis is not expected to be as accurate nor as precise as specific radionuclide analysis after radiochemical separations. Maximum beta energies of approximately 0,1 MeV or higher are well measured. It is possible that low energy beta emitters can not detected (e.g. 3H, 55Fe, 241Pu) or can only be partially detected (e.g. 14C, 35S, 63Ni, 210Pb, 228Ra). The method covers non-volatile radionuclides, since some gaseous or volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation. The method is applicable to test samples of drinking water, rainwater, surface and ground water as well as cooling water, industrial water, domestic and industrial wastewater after proper sampling, sample handling, and test sample preparation (filtration when necessary and taking into account the amount of dissolved material in the water). The method described in this document is applicable in the event of an emergency situation, because the results can be obtained in less than 1 h. Detection limits reached for gross alpha and gross beta are less than 10 Bq/l and 20 Bq/l respectively. The evaporation of 10 ml sample is carried out in 20 min followed by 10 min counting with window-proportional counters. It is the laboratory's responsibility to ensure the suitability of this test method for the water samples tested.

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.

Advanced technical ceramics - Mechanical properties of monolithic ceramics at room temperature - Part 2: Determination of Young's modulus, shear modulus and Poisson's ratio

This part of EN 843 specifies methods for determining the elastic moduli, specifically Young’s modulus, shear modulus and Poisson’s ratio, of advanced monolithic technical ceramics at room temperature. This European Standard prescribes four 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 flexure. 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, shear modulus and Poisson’s ratio from the time-of-flight of an ultrasonic pulse. D The determination of Young’s modulus from the fundamental natural frequency of a struck bar (impulse excitation method). All the test methods assume the use of homogeneous test pieces of linear elastic materials. NOTE 1 Not all ceramic materials are equally and linearly elastic in tension and compression, such as some porous materials and some piezoelectric materials. With the exception of Method C, the test assumes that the test piece has isotropic elastic properties. Method C may be used to determine the degree of anisotropy by testing in different orientations. NOTE 2 An ultrasonic method for dealing with anisotropic materials (ceramic matrix composites) can be found in ENV 14186 (see Bibliography). An alternative to Method D for isotropic materials using disc test pieces is given in Annex A. NOTE 3 At high porosity levels all of the methods except Method C can become inappropriate. The methods are only suitable for a maximum grain size (see EN 623-3), excluding deliberately added whiskers, of less than 10 % of the minimum dimension of the test piece. NOTE 4 The different methods given in this European Standard can produce slightly different results on the same material owing to differences between quasi-isothermal quasi-static an

Welding and allied processes - Symbols for welding - Welded joints (ISO/DIS 2553:2026)

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.
