ISO 8578:2012 specifies the format for the marking of data or symbols for optical characteristics on microscope objectives and eyepieces and the positioning of the data. It makes recommendations for the marking of additional information, particularly colour coding of rings designating the magnification of objectives and the immersion media with which they are used.
Nanomanufacturing - Key control characteristics - Part 2-1: Carbon nanotube materials - Film resista...
IEC/TS 62607-2-1:2012(E) which is a technical specification, provides a standardized method for categorizing a grade of commercial carbon nanotubes in terms of their electrical properties to enable a user to select a carbon nanotube material suitable for his application. The method is intended to assess whether the delivered materials from different production batches of the same production…
High-voltage switchgear and controlgear - Part 107: Alternating current fused circuit-switchers for ...
IEC 62271-107:2012 applies to three-pole operated units for distribution systems that are functional assemblies of a circuit-switcher and current-limiting fuses designed so as to be capable of:
- breaking, at the rated recovery voltage, any load or fault current up to and including the rated short-circuit breaking current;
- making, at the rated voltage, circuits to which the rated short-circuit…
Appareillage à haute tension - Partie 107: Circuits-switchers fusiblés pour courant alternatif de te...
La CEI 62271-107:2012 s'applique aux appareils à man uvre tripolaire pour les réseaux de distribution, qui sont des ensembles fonctionnels constitués d'un circuit-switcher et de fusibles limiteurs, conçus de façon à être capables:
- de couper, à la tension de rétablissement assignée, tout courant de charge ou de défaut jusqu'au pouvoir de coupure en court-circuit assigné y compris…
Medical electrical equipment - Part 2-26: Particular requirements for the basic safety and essential...
IEC 60601-2-26:2012 standard applies to basic safety and essential performance of electroencephalographs used in a clinical environment (e.g., hospital, physician's office, etc.). This standard does not cover requirements for other equipment used in electroencephalography. This third edition cancels and replaces the second edition of IEC 60601-2-26 published in 2003. The aim of this third…
Appareils électromédicaux - Partie 2-26: Exigences particulières pour la sécurité de base et les per...
La CEI 60601-2-26:2012 s'applique à la sécurité de base et aux performances essentielles des électroencéphalographes utilisés dans un environnement hospitalier (par exemple, hôpital, cabinet médical, etc.). Les exigences propres à d'autres appareils également utilisés en électroencéphalographie ne sont pas du domaine de cette norme. Cette troisième édition annule et remplace la deuxième…
Fibre optic interconnecting devices and passive components - Basic test and measurement procedures -...
IEC 61300-3-38:2012 describes the measurement methods necessary to characterise the group delay properties of passive devices and dynamic modules. From these measurements further parameters like group delay ripple, linear phase deviation, chromatic dispersion, dispersion slope, and phase ripple can be derived. In addition, when these measurements are made with resolved polarization, the…

La CEI 61300-3-38:2012 décrit les méthodes de mesure nécessaires pour caractériser les propriétés du retard de groupe de dispositifs passifs et de modules dynamiques. A partir de ces mesures, on peut déduire d'autres paramètres tels que la fluctuation du retard de groupe, l'écart de phase linéaire, la dispersion chromatique, la pente de dispersion et la fluctuation de phase. En outre,…
Information technology — Security techniques — Lightweight cryptography — Part 1: General
ISO/IEC 29192-1:2012 provides terms and definitions that apply in subsequent parts of ISO/IEC 29192. ISO/IEC 29192-1:2012 sets the security requirements, classification requirements and implementation requirements for mechanisms that are proposed for inclusion in subsequent parts of ISO/IEC 29192.
Global maritime distress and safety system (GMDSS) - Part 15: Inmarsat FB500 ship earth station - Op...
IEC 61097-15:2012(E) specifies the minimum operational and performance requirements, technical characteristics, methods of testing and required test results for Inmarsat FB500 ship earth stations (SES), capable of transmitting and receiving distress and safety communications, initiating and receiving distress priority calls and transmitting and receiving general radiocommunications, using…
