Le présent document donne des recommandations relatives au choix, au stockage et à la manipulation du substrat, et indique les caractéristiques essentielles des méthodes d’essai de l’adhérence par traction permettant de vérifier la qualité de la liaison adhésive entre les matériaux dentaires de restauration et la structure dentaire, c’est-à-dire l’émail et la dentine. Certaines méthodes d’essai…

IEC TS 61936-0:2023 provides principles to ensure the coherence amongst HV publications to be observed necessary for the coordination of the design, selection of equipment, operation, and maintenance activities for erection of electrical HV installations to ensure the safety of such systems. In the context of this document, "safety" relates to the safety of persons, domestic animals,…

IEC PAS 63472:2023 describes dimensional options for CONFIGURATION FF AC/DC contact-tube vehicle couplers as defined in IEC 62196-3. These possibilities serve to improve the reliability of a mated connection when the charging cable is not axially constrained. The options can be implemented optionally and maintain mating compatibility with CONFIGURATION FF according to IEC 62196-3.

IEC 61439-5:2023 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: - used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V AC (see Figure 101 for a typical distribution network) and DC systems not exceeding 1 500 V DC; - stationary; - open…

L'IEC 61439-5:2023 définit les exigences spécifiques aux ensembles pour réseaux de distribution publique d'électricité (ERD). Les ERD remplissent les critères suivants: - ils sont utilisés pour la distribution de l'énergie électrique dans des systèmes triphasés pour lesquels la tension assignée ne dépasse pas 1 000 V en courant alternatif (se reporter à la Figure 101 qui…

This document specifies requirements for the design, manufacture, operation, safety, performance, acceptance tests and designation system of deep-sea hydraulic winch equipment (hereafter referred to as “winch equipment”). The deep-sea hydraulic winch equipment are intended to be used for large load deep-sea operations in depths of 3 000 m to 11 000 m.

This document specifies a method for the determination of total phosphate content of natural rubber latex concentrate. This method is not necessarily suitable for latex from natural sources other than the Hevea brasiliensis.

This document describes minimum requirements for performance evaluation of applying fluorescent nanoparticles in quantitative immuno-histochemistry.

This document specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) lattices. The method is applicable to hot (approximately 50 °C) emulsion polymerized SBR lattices having a bound styrene content, expressed on the SBR content, of up to 55 % and to cold (approximately 5 °C) emulsion polymerized SBR lattices having a bound styrene content between…
