ISO/IEC 30171-1:2022 provides the general overview of base-station based underwater wireless acoustic networks (B-UWANs). It gives detailed description for main components of B-UWAN and also provides functions of B-UWAN components. It further specifies the requirements of B-UWAN.

This document defines a set of compression methods for coding one or more images of bi-level, continuous-tone greyscale, or continuous-tone colour, or multichannel digital samples. This document: —    specifies decoding processes for converting compressed image data to reconstructed image data; —    specifies a codestream syntax containing information for interpreting the compressed image data…

IEC 60072-1:2022 is applicable for the majority of rotating electrical machines for industrial purposes within the dimension range and output powers. - Foot- mounted: shaft heights: 56 mm to 400 mm - Flange- mounted: pitch circle diameter of flange: 55 mm to 1 080 mm. This seventh edition cancels and replaces the sixth edition published in 1991. This edition includes the following significant…

IEC 60072-1:2022 s'applique à la majorité des machines électriques tournantes pour usages industriels qui relèvent de la plage de dimensions et des puissances concernées: - Fixation par pattes: hauteur d'axe; entre 56 mm et 400 mm. - Fixation par bride: diamètre du cercle primitif de la bride: entre 55 mm et 1 080 mm. Cette septième édition annule et remplace la sixième édition parue…

This document specifies two methods of testing for checking the leaktightness of assembled joints between mechanical fittings and plastic pressure pipes with diameters up to and including 63 mm. The test applies regardless of the design and material of the fitting used for jointing plastics pipe. This test method is not applicable to fusion-welded joints.

This document specifies a method for the determination of the fat content of all types of cheese and processed cheese products containing lactose of below 5 % (mass fraction) of non-fat solids, and all types of caseins and caseinates. The method is not applicable to fresh cheese types containing, for example, fruits, syrup or muesli. For such products, the Schmid-Bondzynski-Ratzlaff (SBR)…

Le présent document spécifie deux méthodes d’essai pour la vérification de l’étanchéité des assemblages entre raccords mécaniques et tubes sous pression en plastique dont le diamètre est inférieur ou égal à 63 mm. L’essai s’applique quelles que soient la conception et la matière du raccord utilisé pour le raccordement du tube plastique. La présente méthode d’essai n’est pas applicable aux…

Le présent document définit les spécifications traitant des essais de laboratoire effectués avec des sièges conçus pour les passagers et le personnel des véhicules ferroviaires de traction et de remorquage. Il concerne les vibrations rectilignes triaxiales relevant de la gamme de fréquences comprise entre 0,5 Hz et 50 Hz. Il spécifie les vibrations d’entrée à utiliser pour l’essai du siège. Le…

This document defines specifications covering laboratory tests for seats designed for passengers and crew in railway tractive and trailer vehicles. It concerns tri-axial rectilinear vibration within the frequency range 0,5 Hz to 50 Hz. It specifies the input test vibration to be used at seat testing. This document makes it possible to characterize, in the form of frequency response functions, the…
