IEC 61757-4-3: 2020 defines terminology, structure, and a characteristic test method of an optical current sensor using the polarimetric method. It addresses the current sensing element only and not the additional devices that are unique to each application. Generic specifications for fibre optic sensors are defined in IEC 61757. As the specifications of optical polarimetric fibre current sensors…

IEC TS 62607-6-13:2020 establishes a standardized method to determine the chemical key control characteristic • oxygen functional group content on graphite oxide, graphene oxide, reduced graphene oxide and other types of functionalized graphene by • Boehm titration method. In this document, the measured functional groups are carboxyl groups (also in the form of their cyclic anhydrides),…

IEC TS 62910:2020 is available as IEC TS 62910:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC TS 62910:2020 provides a test procedure for evaluating the performance of Under Voltage Ride-Through (UVRT) functions in inverters used in utility-interconnected Photovoltaic (PV) systems.…

This document specifies guidance on the specification of technically specified rubber (TSR). A grading system is proposed, based on the origin of the natural rubber content and on properties exhibited by the rubber. This document is intended for use by parties involved in the procurement of TSR and is intended to form a basis from which requirements for a particular case may be more closely…

IEC 62890:2020 establishes basic principles for Life-Cycle-Management of systems and components used for industrial-process measurement, control and automation. These principles are applicable to various industrial sectors. This standard provides definitions and reference models related to the life-cycle of a product type and the life time of a product instance, It defines a consistent set of…

IEC 61280-4-5:2020 is applicable to the measurement of attenuation and determination of polarity and length of installed multimode and single-mode optical fibre cabling plant, terminated with MPO connectors, using test equipment having an MPO interface. This cabling plant can include multimode or single-mode optical fibres, connectors, adapters, splices, and other passive devices. The cabling can…

IEC SRD 63199:2020 presents the current status of the IEC systems committee Smart Energy (SyC SE) development plan for readers (not limited to IEC smart energy related members). The document identifies items that require standardization, their current status and work required, possibly by multiple technical committees or working groups, to address any issues. Since the content of this document…

IEC 62890:2020(E) establishes basic principles for Life-Cycle-Management of systems and components used for industrial-process measurement, control and automation. These principles are applicable to various industrial sectors. This standard provides definitions and reference models related to the life-cycle of a product type and the life time of a product instance, It defines a consistent set of…

IEC 60601-1-6:2010+A1:2013+A2:2020 specifies a process for a manufacturer toanalyse, specify, design, verify and validate usability, as it relates to basic safety and essential performance of medical electrical equipment. This usability engineering process assesses and mitigates risks caused by usability problems associated with correct use and use errors, i.e., normal use. It can be used to…
