This document specifies the minimum requirements and the test methods for meteorological balloons made from natural rubber latex or natural rubber latex compounded with synthetic rubber emulsion. This document applies to two types of balloons: —     Type 1: meteorological balloon by dipping process; —     Type 2: meteorological balloon by moulding process.

This document specifies a volumetric method for the determination of silver on a material considered homogeneous. The silver content of the sample lies preferably between (100 and 999,0) parts per thousand (‰) by mass. Fineness above 999,0 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15096). This method is intended to be used as the reference method for the…

Le présent document spécifie les caractéristiques de l'alliage à forger mis en forme à froid à base de cobalt, de chrome, de nickel, de molybdène et de fer utilisé dans la fabrication des implants chirurgicaux, et les méthodes d'essai correspondantes. NOTE            Les propriétés mécaniques d'un échantillon prélevé sur un produit fini fabriqué avec cet alliage peuvent différer de…

IEC 60913:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60913:2024 edition 3.0 and the previous IEC 60913:2013 edition 2.0. Furthermore, comments from IEC TC 9 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…

This document provides a collection of representative use cases of AI applications in a variety of domains.

IEC 60947-5-7:2024 states the requirements for proximity devices that correspond to the scope of IEC 60947-5-2:2019 with analog output (PDAO) and/or a digital output to transmit a corresponding digital value representing the detected sensing input. These devices can provide additional parameters. This second edition cancels and replaces the first edition published in 2003. This edition…

L'IEC 60947-5-7:2024 établit les exigences relatives aux détecteurs de proximité relevant du domaine d'application de l'IEC 60947-5-2:2019 qui comportent une sortie analogique (PDAO, Proximity Devices with Analog Output) et/ou une sortie numérique pour transmettre une valeur numérique correspondante qui représente l'entrée sensible détectée. Ces appareils peuvent fournir des…

IEC 62282-6-107:2024 covers micro fuel cell power systems, micro fuel cell power units and fuel cartridges using hydrogen produced from water-reactive (UN Division 4.3) compounds as fuel. These systems and units use proton exchange membrane (PEM) fuel cell technologies. The designs can include fuel processing subsystems to derive hydrogen gas from the water-reactive fuel formulation. This…

IEC 62282-6-107:2024 traite des systèmes à micropiles à combustible, des unités d’alimentation électrique des micropiles à combustible et des cartouches de combustible qui utilisent comme combustible l’hydrogène produit à partir de composés hydroréactifs (division 4.3 des Nations Unies). Ces systèmes et unités d’alimentation utilisent des technologies de piles à combustible à membrane à échange…

IEC 62631-2-3:2024 specifies the measuring technology and the test method for the relative permittivity and dielectric dissipation factor of thin single layer insulating polymer film without any additional metallization on the sample surface. The adaptive thickness range is approximately 10 μm to 100 μm. The proposed frequency is the power frequency (50 Hz or 60 Hz), and it is also suitable in…
