Radio Data System (RDS) - VHF/FM sound broadcasting in the frequency range from 64,0 MHz to 108,0 MH...
IEC 62106-9:2021 specifies the Radio Broadcast Data System (RBDS), which is an RDS-compatible variant used in countries of North America. RBDS was first standardized by the U.S. National Radio Systems Committee (NRSC) in 1993 and subsequently revised in 1998, 2004, 2005 and 2011 . With the publication of this edition of IEC 62106, the RDS and RBDS standards are now harmonized into a single…
Uninterruptible power systems (UPS) - Part 1: Safety requirements
IEC 62040-1:2017+AMD1:2021 applies to movable, stationary, fixed or built-in UPS for use in low-voltage distribution systems and that are intended to be installed in an area accessible by an ordinary person or in a restricted access area as applicable, that deliver fixed frequency AC output voltage with port voltages not exceeding 1 000 V AC or 1 500 V DC and that include an energy storage device…
Alimentations sans interruption (ASI) - Partie 1: Exigences de sécurité
IEC 62040-1:2017+AMD1:2021 s'applique aux ASI mobiles, stationnaires, fixes ou intégrées destinées à une utilisation dans des réseaux de distribution basse tension et à être installées dans une zone accessible par une personne ordinaire ou une zone d'accès restreint, selon le cas, qui fournissent une tension de sortie en courant alternatif à fréquence fixe avec des tensions au niveau de…
Maritime navigation and radiocommunication equipment and systems - Shipborne voyage data recorder (V...
IEC 61996-1:2013+A1:2021 specifies the minimum performance requirements, technical characteristics, methods of testing and required test results, for shipborne voyage data recorder (VDR) installations as required by Chapter V of the International Convention for Safety of Life at Sea (SOLAS), as amended. It takes account of IMO resolution A.694(17) and is associated with IEC 60945. When a…
Matériels et systèmes de navigation et de radiocommunication maritimes - Enregistreur de données de ...
L'IEC 61996-1:2013+A1:2021 spécifie les exigences de performance, caractéristiques techniques et méthodes d'essai minimales ainsi que les résultats d'essai exigés pour les enregistreurs des données du voyage (VDR) de bord, comme exigé par le Chapitre V de la Convention internationale pour la sauvegarde de la vie humaine en mer (SOLAS – International Convention for the Safety of…
Data quality — Part 81: Data quality assessment: Profiling
This document specifies a procedure for data profiling to generate the foundation for performing data quality assessment. This profiling is applicable to data sets that are either originally in a structure of tables and columns or are the output from a transformation to create such a structure.
NOTE 1 Data profiling is applicable to all types of database technology.
The following are within…
Glass‐reinforced thermosetting plastics (GRP) pipes — Determination of the apparent axial long‐term ...
This document specifies a method for determining the apparent axial long-term modulus of pipes subject to beam bending deflection between vertically supported end-couplers, which allow rotation of the pipe relative to the couplers.
In conjunction with ISO 10928, this document expresses the results of the test as an apparent axial long-term modulus for use in the calculation of mid-span beam…
Plastics — Temperature modulated DSC — Part 3: Separation of overlapping thermal transitions
This document specifies a method for the separation of overlapping thermal transitions of plastics related to reversing and non-reversing heat flow rate, using temperature modulated differential scanning calorimetry.
