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.

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.

Suvirinimas ir panašūs procesai. Suvirinimo simboliai. Suvirintosios jungtys (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.

Kranai. Varikliniai suktuvai ir keltuvai. 1 dalis. Varikliniai suktuvai

This document is applicable to the design, information for use, maintenance and testing of power-driven winches for which the prime mover is an electric motor, hydraulic motor, or pneumatic motor. Winches are designed for the movement or manipulation of loads supported on level or inclined planes in situations where risks resulting from a failure of the winding mechanism or pulling medium are mitigated by external measures. This document is not applicable to devices which handle suspended loads. Generally, a winch is used without any additional transport movement, except in cases where a winch is used on a stranded vehicle for self-recovery of the vehicle. Applications of winches covered are for example, but not limited to: a) rope winches; b) belt winches, except steel belts used as pulling media; c) traction winches, including double capstan and traction sheave winches. These types of winches a) to c) also include the following specific applications: — vehicle recovery winches; — winches for boat trailers; — winches for stationary offshore applications. NOTE Examples are shown in Annex H. This document does not apply to: — power-driven hoists in accordance with EN 14492-2; — forestry winches in accordance with EN ISO 19472-1; — winches for seagoing vessels and mobile offshore units; — winches for the lifting of persons; — NGL building hoists in accordance with EN 14492-2; — winches for the handling of hot molten masses. This document deals with the significant hazards, hazardous situations or hazardous events relevant to power driven winches when used as intended and under conditions of misuse which are reasonably foreseeable, identified in Annex A. This document does not specify additional requirements for hazards related to the use of power driven winches in explosive atmospheres in underground mines.

Vandens kokybė. Visuminis alfa ir visuminis beta aktyvumas. Tyrimo metodas naudojant ploną šaltinio sluoksnį (ISO/DIS 10704:2025)

Warning — Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices. IMPORTANT — It is absolutely essential that tests conducted in accordance with this document be carried out by suitably qualified staff. This document specifies a method for the determination of gross alpha and gross beta activity concentrations 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 cannot be detected (e.g. 3H, 55Fe, 241Pu) or can only be partially detected (e.g. 14C, 35S, 63Ni, 210Pb, 228Ra). If the presence of low-energy beta emitters is strongly suspected, liquid scintillation analysis is recommended (ISO 11704). The method described in this document applies to non-volatile radionuclides, since some gaseous or volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation. The method described in this document is applicable to test samples of drinking water, rainwater, sea water, 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 can be used 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-1 and 20 Bq·l-1, respectively, for instance for rainwater water. The evaporation of a 10 ml sample can be carried out in 20 min followed by 10 min counting using a gas-flow -proportional counter with window. It is the laboratory’s responsibility to ensure the suitability of this test method for the water samples tested.
