This document specifies the sequence of methods for characterizing the structural properties of graphene, bilayer graphene and graphene nanoplatelets from powders and liquid dispersions using a range of measurement techniques typically after the isolation of individual flakes on a substrate. The properties covered are the number of layers/thickness, the lateral flake size, the level of disorder,…

This document specifies the conditions and methods used for testing and characterizing the water distribution patterns of irrigation sprinklers. The term sprinkler is used in this document in a broad generic sense and is meant to cover a wide variety of products. The specific performance measurements addressed include distribution uniformity, wetted radius, and water jet trajectory height. This…

L’IEC 60704-1:2021 s’applique aux appareils électriques pour usages domestiques et analogues, y compris leurs accessoires ou composants, alimentés à partir du réseau ou par piles ou accumulateurs. L’expression "usages analogues" s’entend des usages dans des conditions similaires à celles des foyers domestiques, par exemple dans les restaurants, cafés, salons de thé, hôtels, salons de…

L’IEC 61800-2:2021 s’applique aux entraînements électriques de puissance à vitesse variable en courant alternatif, incluant les convertisseurs à semiconducteurs et les moyens permettant de les commander, de les protéger, de les surveiller, de les mesurer, ainsi que les moteurs à courant alternatif. Elle s’applique aux entraînements électriques de puissance à vitesse variable destinés à alimenter…

This document specifies general requirements for eye and face protectors. These protectors are intended to provide protection for the eyes and faces of persons against one or more common occupational hazards such as impacts from flying particles and fragments, optical radiation, dusts, splashing liquids, molten metals, heat, flame, hot solids, harmful gases, vapours and aerosols. Additional…

Le présent document spécifie les exigences générales relatives aux protecteurs des yeux et du visage. Ces protecteurs sont destinés à assurer une protection des yeux et du visage de personnes contre les risques professionnels courants, tels que les impacts de particules et fragments projetés, le rayonnement optique, les poussières, les projections de liquides, les métaux fondus, la chaleur, les…

1 Scope This document specifies mechanisms for the provision of specific, communication-related, non-repudiation services using asymmetric cryptographic techniques.

1 Scope The ISO/IEC 15938 series operates on and generates conformant bitstreams. This document provides a specific implementation that behaves in a conformant manner. NOTE 1 Other implementations that conform to the ISO/IEC 15938 series are possible, which do not necessarily use the algorithms or the programming techniques of the reference software. The software contained in this document is…

This document describes general test methods for determining the water vapour transmission rate of sheet materials by means of a dynamic gas method or a static gas method. Depending on the method and specific apparatus employed, materials up to 38 mm thick and with water vapour transmission rates in the range from 0,05 g/(m2·d) to 65 g/(m2·d) can be tested. The basis of the function of the…
