This document specifies a method for measuring the adhesion of the finish to leather or the adhesion between two adjacent layers of the finish. The method is valid for all finished flexible leathers with a smooth surface that can be bonded to an adherent plate without the adhesive penetrating into the finish. Preliminary experiments can be necessary to determine whether these conditions are met.…

In order to create punctual timetables, it is necessary to accurately calculate and plan out many values, such as running time between stations, headway between trains, train scheduling, rolling stock scheduling, driver and crew scheduling, operation scheduling in stations and depots and capacity of the line/infrastructure. Among these values, shortest running time between stations must be…

IEC 62232:2022 addresses the evaluation of RF field strength, power density and specific absorption rate (SAR) levels in the vicinity of base stations (BS), also called products or equipment under test (EUT), intentionally radiating in the radio frequency (RF) range 110 MHz to 300 GHz in accordance with the scope, see Clause 1. It does not address the evaluation of current density. RF exposure…

The document addresses specific requirements which are applicable to all types of electronic devices with an integral display such as cell phones, computer tablets, desktop and laptop computers, monitors and printers.

This document specifies a data interchange format for the exchange of deoxyribonucleic acid (DNA) data for person identification or verification technologies that utilize human DNA. Consideration of laboratory procedures is out of scope of this document. This document provides the ability for DNA profile data to be exchanged and used for comparison (subject to privacy regulations) with DNA…

IEC 60071-12:2022 applies guidelines on the procedures for insulation co-ordination of line commutated converter (LCC) stations for high-voltage direct current (HVDC) project, whose aim is evaluating the overvoltage stresses on the converter station equipment subjected to combined DC, AC power frequency, harmonic and impulse voltages, and determining the specified withstand voltages for equipment…

L'IEC 60071-12:2022 applique des lignes directrices concernant les procédures de coordination de l’isolement des stations de conversion équipées de convertisseurs commutés par le réseau (LCC) pour des installations à courant continu haute tension (CCHT), dont l’objectif est d’évaluer les contraintes de surtension exercées sur le matériel soumis à des tensions combinées de fréquence, d'…
