IEC 60127-8:2018(Main)
Miniature fuses - Part 8: Fuse resistors with particular overcurrent protection

IEC 60127-8:2018 relates to fuse resistors with particular overcurrent protection rated up to AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors.
It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere.
The object of this part of IEC 60127 is
a) to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way;
b) to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics;
c) to establish uniform test methods for fuse resistors with particular overcurrent protection, so as to allow verification of the values (for example rated dissipation, functioning characteristic and rated breaking capacity values) specified by the manufacturer.
This part of IEC 60127 applies in addition to the requirements of IEC 60127-1.
This first edition of IEC 60127-8 cancels and replaces IEC PAS 60127-8:2014.
This international standard is to be used in conjunction with IEC 60127-1.

Fibre optic communication subsystem test procedures - Part 2-13: Digital systems - Measurement of error vector magnitude

IEC 61280-2-13:2024 series defines a procedure for calculating the root-mean-square error vector magnitude of optical n-APSK signals from a set of measured symbols. It specifically defines the normalization of the reference states and a procedure for optimal scaling of the measured symbol states. The procedure described in this document applies to single-polarized optical signals as well as to conventional polarization-multiplexed signals with independently modulated polarization tributaries. In general, it is not advisable to apply these procedures without modification to signals, in which optical amplitude, phase, and polarization state are simultaneously modulated to encode the information data. This document does not specify any signal processing steps for extracting the symbols from the received optical signals, because these steps depend on the optical receiver and can vary with the type of the transmitted n-APSK signal. These and optional additional signal processing steps are defined in application-specific documents.

Nanomanufacturing - Key control characteristics - Part 9-2: Nanomagnetic products - Magnetic field distribution: Magneto-optical indicator film technique

IEC TS 62607-9-2:2024, which is a Technical Specification, establishes a standardized method to determine the key control characteristic
• magnetic field distribution
of nanomagnetic materials, structures and devices by the
• magneto-optical indicator film technique.
The magnetic field distribution is derived by utilizing a magneto optical indicator film, which is a thin film of magneto-optic material that is placed on the surface of an object exhibiting a spatially varying magnetic field distribution. The Faraday effect is then employed to measure the magnetic field strength by analysing the rotation of the polarization plane of light passing through the magneto-optic film.
The method is applicable for measuring the stray field distribution of flat nanomagnetic materials, structures and devices.
- The method can especially be used to perform fast quantitative measurements of stray field distributions at the surface of an object.
- The magneto-optic indicator film technique (MOIF) is a fast, non-destructive method, making it an attractive option for materials analysis and testing in the industry.
- MOIF measurements can be done without any sample preparation and do not rely on specific surface properties of the object. It can be applied to the characterization of rough samples as well as of samples with non-magnetic cover layers.
- MOIF can quantitatively measure magnetic field distributions:
• with a one-shot measurement which typically takes a few seconds
• over areas of several square centimetres (over diameters of up to 15 cm with special techniques)
• in a field range from 1 mT to more than 100 mT
• with down to 1 µm spatial resolution
- Although techniques with nano-scale resolution are suitable for analysing the details of magnetic field structure, their ability to characterize larger areas is limited by their scanning area. Therefore, the MOIF technique is an indispensable complementary method that can offer a more comprehensive understanding of material properties.
This document focuses on the calibration procedures, calibrated measurement process, and evaluation of measurement uncertainty to ensure the traceability of quantitative magnetic field measurements obtained through the magneto-optic indicator film technique.

Smart city system ontology - Part 1: Gap analysis

IEC SRD 63476-1:2024 provides a gap analysis on ontology relevant standards for smart city systems to be used as a base document for mapping, developing and maintaining a set of ontology standards for smart city systems.
Ontology is becoming a key subject in the world of big data, AI, IoT, and smart city system standards. The following benefits of ontology are recognized as important with respect to interoperability, connectivity, traceability of digital content, particularly machine readability, executability and interpretability of digital content for decision making and actions.
- Increase interoperability across domains.
- Enable machine-readable code for computational reasoning and decision making.
- Create semantic linkages between data, information and knowledge systems.
- Build accessible APIs and semantic linkages between web-based data objects.
- Link data domains with shared concepts or canonical data models.
- Connect shared data concepts and definitions between domains.
However, ontology has a variety of definitions in different international standards. How to understand different meanings of ontology and select the right definition for the right stakeholders’ concerns for the right purposes is a big challenge for effective integration of business, data, information, knowledge and decision making, across disciplines, domains, systems, platforms and applications in smart cites. Moreover, how to deal with the grand challenges of interoperability of many and various ontologies to satisfy the demands from artificial intelligence and big data analytics are gaps to be filled in the area of smart city systems. How to develop digital content that is machine readable, executable and interpretable, working in the system without human effort for a smart city system are emerging needs to be studied. There are significant demands for better communication, coordination, cooperation, collaboration and connectivity of existing ontology standards to smart cities practical sectors. This document aims:
• to identify existing ontology standards from different Standards Development Organizations (SDOs) and to provide best practice examples and considerations of ontology standards development and maintenance for smart city systems;
• to identify gaps in existing ontology standards for smart city systems and the opportunities and challenges in ontology standards development taking into account multi-dimensional and muti-domain stakeholders’ concerns city wide, and to provide recommendations for ontology standards development and maintenance to enable integration, interoperability, efficiency and effectiveness of smart city systems.

Magnetic materials - Part 1-1: Classification - Surface insulations of electrical steel sheet, strip and laminations

Establishes a classification of surface insulations for electrical steel sheet, strip and laminations according to their general composition, relative insulating ability and function. These surface insulations are either oxide layers or applied coatings. The purpose of this classification is to create a nomenclature for the various types of surface insulations and to assist users of surface insulations by providing general information about the chemical nature and use of the surface insulations. It is not the intent of this classification to specify insulation requirements in terms of specific values of surface insulation resistance. Such requirements are agreed between the purchaser and the steel producer, where applicable. The classification is used in conjunction with the various specifications for cold rolled electrical steels (see the standards in the IEC 60404-8 series in Clause 2).
