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.

Bitumas ir bituminiai rišikliai. Kompleksinio šlyties modulio ir fazės kampo nustatymas. Dinaminis šlyties reometras (DSR)

This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear. From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus. This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

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.
