This document specifies the design and metrological characteristics of point autofocus probe (PAP) instruments for the areal measurement of surface topography. Because surface profiles can be extracted from areal surface topography data, the methods described in this document are also applicable to profiling measurements.

This document specifies requirements for the sampling and analysis of air, surface or bulk material samples analysed by fluorometric detection of an enzyme activity present in filamentous fungi[1] (US Patent No. 6,372,446) to quantitatively determine the total fungal biomass density. It describes the analytical procedure that can be performed on-site or in a laboratory. This method does not…

This document specifies the design and metrological characteristics of coherence scanning interferometry (CSI) instruments for the areal measurement of surface topography. Because surface profiles can be extracted from surface topography data, the methods described in this document are also applicable to profiling measurements.

This document specifies the design and metrological characteristics of a particular non-contact instrument for measuring surface texture using a confocal chromatic probe based on axial chromatic aberration of white light. Additional metrological characteristics can be found in ISO 25178-600. Because surface profiles can be extracted from areal surface topography data, the methods described in…

This document specifies the design, metrological characteristics and nominal characteristics of contact stylus instruments for the areal measurement of surface topography. Because surface profiles can be extracted from areal surface topography data, the methods described in this document are also applicable to profiling measurements.

Le présent document spécifie les dimensions, en millimètres, les forces nominales initiales et le type des ressorts à gaz. Le présent document est applicable aux ressorts à gaz de type 900 à 100 000, gonflés avec de l’azote avec une force nominale initiale comprise entre 900 N ± 5 % et 100 600 N ± 5 %, destinés à être utilisés dans les outillages de presse. Le présent document spécifie également…

This document defines the layout and colorimetric values of targets for use in the calibration of a photographic product/input scanner combination (as used in the preparatory process for printing and publishing). One target is defined for positive colour transparency film and another is defined for colour photographic paper.

Le présent document contient les dispositions relatives à la conception géotechnique qui s'appliquent à une vaste gamme de structures en mer, plutôt qu'à un type particulier de structure. Le présent document décrit les méthodes développées principalement pour la conception des fondations superficielles avec un rapport entre longueur enfouie (L) et diamètre (D) L/D < 0,5, des…

This document contains provisions for geotechnical engineering design that are applicable to a broad range of offshore structures, rather than to a particular structure type. This document outlines methods developed for the design of shallow foundations with an embedded length (L) to diameter (D) ratio L/D < 0,5, intermediate foundations, which typically have 0,5 ≤ L/D ≤ 10 (see Clause 7), and…

IEC 62657-4:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62657-4:2025 specifies a concept and methods for central coordination (CC) of automation applications using…
