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…
Intelligent transport systems (ITS) — Network-based precise positioning infrastructure for land tran...
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…
Poudres métalliques — Méthode d’essai permettant de déterminer la teneur en inclusions non métalliqu...
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…
Metallic powders — Test method for the determination of non-metallic inclusions in metal powders usi...
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…
Biotechnology — Validation of database used for nucleotide sequence evaluation
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…
Chromium ores and concentrates — Determination of chromium content — Titrimetric method
This document specifies a titrimetric method for the determination of the chromium content of chromium ores and concentrates having a chromium content greater than a mass fraction of 7,00 %.
CISPR TR 31: 2024, which is a Technical Report, covers the rationale behind the database containing the characteristics of radio services. The database is a "living document " in the format of a spreadsheet file in the EMC Zone of the IEC web site: https://www.iec.ch/emc/radio-services-database . As new input for the IEC Radio Services Database arrives, this Technical Report provides…
Optics and photonics — Lasers and laser-related equipment — Test methods for the spectral characteri...
This document specifies methods by which the spectral characteristics such as wavelength, bandwidth, spectral distribution and wavelength stability of a laser beam can be measured. This document is applicable to both continuous wave (cw) and pulsed laser beams. The dependence of the spectral characteristics of a laser on its operating conditions may also be important.
