Branduolinio kuro technologija. Urano nustatymas tirpaluose, urano heksafluoride ir kietosiose medžiagose. 1 dalis. Redukavimo geležimi(II) ir oksidavimo kalio dichromatu titrimetrinės analizės metodas (ISO 7097-1:2025)

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, uranyl nitrate hexahydrate, uranium hexafluoride and U3O8 from the nuclear fuel cycle. This procedure is sufficiently accurate and precise to be used for nuclear materials accountability. This method can be used directly for the analysis of most uranium and uranium oxide nuclear reactor fuels, either irradiated or un-irradiated, and of uranium nitrate product solutions. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere, and other elements which could cause interference are not normally present in sufficient quantity to affect the result significantly. The method recommends that an aliquot of sample is weighed and that a mass titration is used, in order to obtain improved precision and accuracy. This does not preclude the use of alternative techniques which could give equivalent performance. The use of automatic device(s) in the performance of some critical steps of the method has some advantages, mainly in the case of routine analysis.

Popierius ir kartonas. Atranka vidutinei kokybei nustatyti (ISO/DIS 186:2026)

This Iinternational Standard specifies a method of obtaining a representative sample from a lot of paper or board, including solid and corrugated fibreboard (see ISO 4046:1978), for testing to determine whether or not its average quality complies with set specifications. It defines the conditions which apply when sampling is carried out to resolve disputes between buyer and seller relating to a defined lot of paper or board, which has been or is being delivered. NOTE If less than 50 % of the lot is available for sampling, then sampling in terms of this International Standard will be invalid in the absence of agreement to the contrary. The method is unsuitable for determining the variability within a lot. In cases where International Standards make reference to sampling according to this standard but where such sampling is impossible, impractical or inappropriate, and where no dispute is involved, guidance is given in normative annex A.

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.
