Cuir — Détermination des alkylphénols éthoxylés — Partie 2: Méthode indirecte
Le présent document spécifie une méthode de détermination des alkylphénols (le nonylphénol et l'octylphénol) et des éthoxylates d'alkylphénol (l'éthoxylate de nonylphénol et l'éthoxylate d'octylphénol) dans le cuir et les produits auxiliaires de traitement. Cette analyse est effectuée par chromatographie en phase liquide à haute performance (CLHP) ou par chromatographie…
Leather — Determination of ethoxylated alkylphenols — Part 2: Indirect method
This document specifies a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries. The analysis is based on high-performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS).
The analysis of the alkylphenol ethoxylate is made by cleaving the…
Railway applications - DC surge arresters and voltage limiting devices - Part 2: Voltage limiting de...
IEC 62848-2:2019 applies to Voltage Limiting Devices (VLDs) to be applied in DC traction systems in order to comply with protective provisions against electric shock from DC, and combined AC – DC voltages, in accordance with the IEC 62128 series, taking into account stray current provisions.
VLDs operate in such a way as to connect the track return circuit of DC railway systems to the earthing…

IEC TS 62600-20:2019 establishes general principles for design assessment of OTEC plants. The goal is to describe the design and assessment requirements of OTEC plants used for stable power generation under various conditions. This electricity may be used for utility supply or production of other energy carriers. The intended audience is developers, engineers, bankers, venture capitalists,…
Health Informatics — Terminology resource map quality measures (MapQual)
This document provides quality requirements for producing a quality map between terminological systems.
This document establishes measures which can be used to assess the quality and utility of a map between terminological resources in order to determine the types and levels of measure required for common use cases in healthcare.
NOTE Examples of such cases include conformity assessment.
