Nuclear fuel technology - Determination of uranium in solutions, uranium hexafluoride and solids - Part 1: Iron(II) reduction/potassium dichromate oxidation titrimetric method (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.

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.

NOTE 101 Examples of such appliances are: — flight conveyor dishwashing machine; — rack conveyor dishwashing machine. Requirements to avoid backsiphonage of non-potable water into the water mains are specified in Annex BB. This document deals with specific requirements on noise emitted from these appliances because the generated noise can be LpA > 70 dB(A) and is considered to be a relevant hazard. See Clause 7.12.104, 22.115 and Annex CC. The electrical part of appliances making use of other forms of energy is also within the scope of this document. This document deals with the reasonably foreseeable hazards presented by appliances that are encountered by all persons in and around the installation place or workplace. NOTE 102 Attention is drawn to the fact that: — for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary; — in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities; — in many countries, additional requirements are specified for appliances incorporating pressurized parts; — for scrapping of appliances, additional requirements can be necessary. This document does not apply to: — commercial electric dishwashing machines under EN IEC 60335 2 58; — appliances designed exclusively for industrial purposes, for example machines used in the food industry for cleaning receptacles that serve as packaging for final products (e.g. bottle-cleaning machines) and machines used in manufacturing processes; — gas heated appliances which are part of the conveyor dishwashing machines; — movable appliances; — dishwashing machines that do not form one functional unit, for example where a transportation device transfers the load from one separate unit to another; — separately driven transport devices not confined in the appliance; — appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); — sterilizers and washer-disinfectors used to treat medical materials (EN IEC 61010 2 040). With this European revision 2.0 of the document, the EN 50416:2005 is superseded. This European revision 2.0 of the document, supplements or modifies the corresponding clauses of the standards below: — EN IEC 60335 1:2023+A11:2023+prA12:2026. Secretary’s note: The above addition has been moved from the Introduction (informative text) to the Scope (normative text) of the standard following discussions with the HAS consultants.

Measurement of CO2 streams - Sampling and analysis for pipeline transportation

This document specifies requirements and recommendations for measuring the composition of CO2 streams during post capture pipeline transportation. The primary objective of this document is to establish standardized technical requirements and recommendations necessary for implementing regulations, commercial contracts, inventory ownership and fiscal transactions within the framework of Carbon Capture and Storage (CCS). This document includes measurements up to the storage injection points but does not cover Measurement, Monitoring, and Verification (MMV) once the CO2 has entered the geological storage complex. The differentiation between biogenic and non-biogenic CO2 in a CO2 stream is recognized as highly relevant for accounting purposes. However, the measurement methodologies for the biogenic CO2 fraction fall outside the scope of this document, which covers post-capture pipeline transportation. This document is not intended to differentiate between biogenic CO2 and CO2 produced from non-biogenic sources.
