ISO/TR 17881-3:2018 describes a method for determining short-chain chlorinated paraffins (C10-C13) (SCCPs) in textiles using carbon skeleton reaction gas chromatography with a flame ionization detector (GC-FID).
ISO/TR 17881-3:2018 is applicable to all kinds of textile products.
Insulation co-ordination - Part 2: Application guidelines
IEC 60071-2:2018 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 60071-2:2018 constitutes application guidelines and deals with the selection of insulation levels of equipment or…
ISO 21012:2018 specifies design, construction, type and production testing, and marking requirements for non-insulated cryogenic flexible hoses used for the transfer of cryogenic fluids within the following range of operating conditions:
- working temperature: from −270 °C to +65 °C;
- nominal size (DN): from 10 to 100.
End fittings for mounting of any couplings are within the scope of…
L'ISO 21012:2018 définit la conception, le type et les tests de production ainsi que les exigences de marquage applicables aux tuyaux flexibles cryogéniques non isolés utilisés pour le passage des fluides cryogéniques dans la plage de conditions de fonctionnement suivante:
- température de service: entre − 270 °C et + 65 °C;
- diamètre nominal (DN): entre 10 et 100.

Insulation co-ordination - Part 2: Application guidelines
IEC 60071-2:2018 constitutes application guidelines and deals with the selection of insulation levels of equipment or installations for three-phase electrical systems. It gives guidance for the determination of the rated withstand voltages for ranges I and II of IEC 60071-1 and to justify the association of these rated values with the standardized highest voltages for equipment. It covers three-…
Coordination de l'isolement - Partie 2: Lignes directrices en matière d'application
L'IEC 60071-2:2018 constitue des lignes directrices en matière d'application et concerne le choix des niveaux d'isolement des matériels ou des installations pour les réseaux triphasés. Elle a pour objet de donner des recommandations pour la détermination des tensions de tenue assignées pour les plages I et II de l'IEC 60071-1 et de justifier l'association de ces valeurs…
Microbeam analysis — Analytical electron microscopy — Selected area electron diffraction analysis us...
ISO 25498:2018 specifies the method of selected area electron diffraction (SAED) analysis using a transmission electron microscope (TEM) to analyse thin crystalline specimens. This document applies to test areas of micrometres and sub-micrometres in size. The minimum diameter of the selected area in a specimen which can be analysed by this method is restricted by the spherical aberration…
