This document specifies the Saunderson correction for different measurement geometries and the solutions of the Kubelka-Munk equation for hiding and transparent layers. It also specifies methods for the calculations of the tinting strength including the residual colour difference based on different criteria such as the depth of shade. Finally, methods for determining the hiding power are provided…

This document provides recommendations and requirements to project developers, decision-makers and managers responsible for authorising, promoting, financing, planning, designing, procuring, managing, reviewing and implementing a project or programme. The recommendations and requirements aim to ensure that a project or programme adds value by aligning its development and implementation with a…

This document gives the essential principles in the application of ISO 25841. It outlines the details of elements applicable in quality management of female condoms as required by related normative standards, as referred in ISO 25841 and other relevant concepts. This document supplements the use of ISO 25841 and addresses quality management aspects to be considered during the development,…

Classes A1a and B1a porcelain (as defined in ISO 13006) are now manufactured in much larger formats than previously available and are increasingly being used as an external cladding material for buildings. Classes A1b, A11a, and AIIb extruded ceramics (as defined in ISO 13006) are not covered by the scope of this document. These materials, when specifically developed for external façade…

This document describes a method for calculating steady-state rollover threshold of heavy commercial vehicles and buses, not considering the effects of active control systems. The calculation method considers the main factors that influence the rollover threshold, namely the height of centre of gravity, the track, the tyre lateral stiffness, and all factors that affect the vehicle roll stiffness…

This document establishes: —    principles and methods for the performance assessment of presentation attack detection (PAD) mechanisms; —    reporting of testing results from evaluations of PAD mechanisms; and —    a classification of known attack types (Annex A). Outside the scope are: —    standardization of specific PAD mechanisms; —    detailed information about countermeasures (i.e. anti-…

IEC 62146-2:2023 is applicable to TRV capacitors used on high-voltage alternating current circuit-breakers with rated voltages above 100 kV with 50 Hz or 60 Hz. TRV capacitors are installed phase to earth, either in parallel to the bushing on dead tank circuit-breakers, or immersed inside the circuit-breaker, or freestanding close to the circuit-breaker. Their function is to limit the transient…

IEC 62146-2:2023 s’applique aux condensateurs TTR utilisés sur les disjoncteurs à courant alternatif haute tension dont les tensions assignées sont supérieures à 100 kV à 50 Hz ou 60 Hz. Les condensateurs TTR à neutre reliés à la terre sont installés soit parallèlement à la traversée sur les disjoncteurs à cuve mise à la terre, soit immergés à l’intérieur du disjoncteur, soit de façon autonome à…

This document specifies content-related aspects of terminology database maintenance. It gives guidance on the content of terminological data collections, with emphasis on data quality evaluation. This document gives guidance for modellers of concept entries who need to ensure interoperability and high-quality content. It aims to ensure that terminological data collections themselves meet high…
