Komentavimo iki data 2026-08-04

Adityvioji gamyba. Kvalifikacinio vertinimo principai. 1 dalis. Dažniausiai pasitaikantys gedimų tipai, naudojami procesų rizikos plano sudarymui (ISO/ASTM DIS 52954-1:2026)

This document identifies common failure modes, which can occur within operations across additive manufacturing (AM) process categories defined in ISO/ASTM 52900. It lists state-of-the-art failure modes, which can lead to risks within AM parts and equipment, as well as providing informative examples of corresponding failure effects and mitigation actions. This document can be used to aid manufacturers in their risk management. While doing so it supports the implementation of AM as a production method within critical applications and regulated industries. This document helps to address the requirements for risk management set by regulated industries for part and production method compliance. Technology specific failure modes will be addressed in separate standards, including but not limited to PBF-LB/M, PBF-LB/P, MEX, MJT, BJT, and DED. This document aims to close the existing gap between general risk management standards, such as ISO 31000 or ISO 14971 (medical), and the know-how gap of existing failure modes of the AM process category and their integrated workflow. The standard maps risks according to AM processes defined within ISO/ASTM 52920. This document does not cover environment, health and safety risks and will not measure, assess, or evaluate the risk impact on the AM part to be produced. It does not list the part specific input and output parameters, during the respective process steps. This task is dedicated to the risk management evaluation teams, which usually comprise quality managers and product domain specific experts. The document enables all part owners and manufacturers to use it for the risk mapping activities, to support subsequent risk assessments, continuous improvement, validation planning, estimation of manufacturing efforts, and conformity audits. For risk examples that are relevant only to specific AM machinery brands, manufacturers might consider use of the informative annex.

This part of ISO 13164 gives general guidelines for sampling, packaging, and transporting of all kinds of water samples, for the measurement of the activity concentration of 222Rn. The test methods fall into two categories: a) direct measurement of the water sample without any transfer of phase (see ISO 13164-2[7]); b) indirect measurement involving the transfer of the 222Rn from the aqueous phase to another phase (see ISO 13164-3[8] and 13164-4[9]). The test methods can be applied either in the laboratory or on-site. The laboratory is responsible for ensuring the suitability of the test method for the water samples tested.

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.

Žemės ir miškų ūkio mašinos. Malkų ruošimo mašinos. Sauga

This document specifies safety requirements and their verification for the design and construction of firewood processors, designed to be used for making firewood. Firewood processors are combined machinery that cut and then split the wood. This document covers machines where the cutting is done either by a chain blade or a circular saw, and splitting movement is done horizontally or near horizontally by one or more splitting wedges. If cutting or splitting is done by other means, e.g. by guillotine blade or vertical movement splitting, this document is not applicable. This document is not applicable for machinery, where the wood is required to be moved from cutting to the splitting by manual handing by the operator. This document deals with firewood processors that are designed in a way that only one operator carries out the work process, but it is foreseeable that other operators, e.g. for loading or unloading, will work on or close to the machine. This document deals with all significant hazards, hazardous situations and hazardous events relevant to these machines, when they are used as intended and under the conditions foreseen by the manufacturer. See Clause 4 for the list of significant hazards. This document is not applicable to machines which were manufactured before the date of its publication. This document is applicable for manually operated, semi-automatic and automatic firewood processors. This document is applicable to the following possible integral features of the firewood processor: - Integral outfeed conveyors - Integral infeed conveyors - Integral hold to run operated log lifting device Other accessories or added features of firewood processors are not covered by this document. These could be e.g.: - Separate conveyors or tables that are not integral parts of the machine - Other wood lifting equipment (e.g. winch or crane) - Other separate accessories of the machine, e.g. for cleaning the wood or packing the wood.

Viešasis transportas. Pamatinių duomenų modelis. 8 dalis. Valdymo informacija ir statistika

Transmodel is composed of 10 parts (see above). This work item consists in the revision and update of the documentation of the Public transport reference data model – Part 8 (Transmodel – Part 8). The update consists basically of the following types of actions: a. Simplication of Part 8 based on the revision of Part 1: several functional extensions of Transmodel took place since the last publication of EN12896 (in 2016 and 2019). The functional extensions elaborated until 2019 generated additional common concepts which have already been published in the relevant documents. These additional common concepts are now integrated into Transmodel - Part 1 and thus removed from Part 8. b. Updates/extensions of Part 8 as a consequence of • Work presented in TR17370:2019. This TR provides a list of KPIs calculated using operational raw data. The action consists here to provide data model extracts, representing the raw data needed for several KPIs (listed in TR17370:2019), The extracted sub-models are based upon the (already existing) "Loggable object model" and will complete the 2 examples published in the current version of Part 8. c. Ensuring coherence of the Transmodel eco-system. Several updates of Transmodel- Part 8 result from the discussions lead with the OpRa group and intend to ensure coherence with the OpRa Technical Specification.
