This document specifies an analytical method for determining the neptunium concentration by spectrophotometry, with spectrophotometer implemented in hot cell or glove box allowing the analysis of high activity solutions, with a standard uncertainty, with coverage factor k = 1 of about 5 %, in nitric acid solutions after the dissolution of nuclear reactor irradiated fuels, at different steps of…

This document establishes the general specifications, requirements and tests for decomposition blockers located on the high-pressure side in battery vehicles and gas containers as defined in EN 13807 or in acetylene bundles as defined in ISO 10961. NOTE 1       The terms “upstream” and “downstream” refer to the normal direction of gas flow in the decomposition blocker. 1 bar = 0,1 MPa = 105 Pa; 1…

This document builds upon ISO/IEC 14882 by describing requirements for implementations of an interface that computer programs written in the C++ programming language could use to invoke algorithms with concurrent execution. The algorithms described by this document are realizable across a broad class of computer architectures. This document is written as a set of differences from the base…

IEC/IEEE 63253-5713-8:2024 describes electrical and mechanical requirements of single-phase station service voltage transformers with system voltages of 46 kV or higher and with the maximum rated voltage of the power winding of 1 000 V. This document is a basis for the establishment of performance and limited electrical and mechanical interchangeability requirements of the equipment are…

This document specifies the functional requirements of nomadic devices for lane-level positioning and integrity monitoring with the network-based precise positioning infrastructure for land transportation (NETPPI-LT), a lane-level positioning system based on global navigation satellite systems (GNSS) described in ISO/TR 22086-1. This document identifies the GNNS threats to monitor and the errors…

Le présent document spécifie une méthode d’essai métallographique permettant de déterminer la teneur en inclusions non métalliques dans les poudres métalliques à l’aide d’une éprouvette frittée-forgée. La méthode d’essai est applicable aux éprouvettes frittées-forgées par recompression dans lesquelles s’est produit un écoulement latéral minime (< 1 %). Le cœur de l’éprouvette frittée-forgée ne…

This document specifies a metallographic test method for determining the non-metallic inclusion level in metal powders using a powder-forged specimen. This test method is applicable to repress powder-forged test specimens in which there has been minimal lateral flow (<1 %). The core region of the powder-forged test specimen must not contain porosity detectable at 100x magnification. This test…

This document describes a practical procedure for nucleotide sequence database evaluation and validation. This document describes minimum requirements for the validation of a nucleotide sequence database. This document is applicable only for databases consisting of entries of nucleotide sequences. This document is not applicable to the general evaluation of the entire database quality including…
