IEC 60512-99-003:2023 is used for the assessment of connectors within the scope of SC 48B that are used in balanced single-pair communication cabling with remote power, in support of e.g., IEEE 802.3 remote powering applications for point-to-point connections. The object of this document is to detail a test schedule to determine the ability of sets of single-pair connectors as defined in the IEC…

IEC TS 63291-2:2023 defines aspects on planning, specification, and execution of multi-vendor HVDC grid systems also referred to as HVDC grids. The terms "HVDC grid systems" or "HVDC grids" are used in this document to describe HVDC systems for power transmission having more than two HVDC stations connected to a common DC circuit. The DC circuit can be of radial or meshed…

IEC 62056-6-2:2023 specifies a model of a meter as it is seen through its communication interface(s). Generic building blocks are defined using object-oriented methods, in the form of interface classes to model meters from simple up to very complex functionality. Annexes A to F (informative) provide additional information related to some interface classes This fourth edition cancels and…

IEC 62056-5-3:2023 specifies the DLMS®/COSEM application layer in terms of structure, services and protocols for DLMS®/COSEM clients and servers, and defines rules to specify the DLMS®/COSEM communication profiles. It defines services for establishing and releasing application associations, and data communication services for accessing the methods and attributes of COSEM interface objects,…

IEC 62056-8-12:2023 describes the use of DLMS®/COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMS®/COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN. This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN.…

This document defines a test method which enables the determination of the characteristic values of discharge flow rate and thermal losses of gas-loaded accumulators with separators used in fluid power systems.

IEC TS 63189-1:2023 covers the terms and definitions, system composition and control modes of virtual power plant (VPP). It defines the functional requirements for VPPs, including power generation forecasting, load forecasting, generation and consumption scheduling, control and management of energy storage devices and loads, coordinated optimization of distributed energy resources, status…

IEC 62977-3-5:2023 specifies standard evaluation methods for determining the colour capabilities of electronic display modules and systems with respect to colour accuracy, colour gamut volume, and their intersection with a reference colour space. Also included is evaluation with respect to the chromaticity gamut area. These methods apply to emissive and transmissive direct view displays that…

This document defines the general criteria for the development of flight-to-ground umbilical systems used by a space system. These criteria apply to the service arms or equivalent mechanisms, umbilical carriers and plates, couplings, connectors, withdrawal and retract devices, handling mechanisms and control systems for mechanisms, as well as the prevention of accidental cross-connection.

This document specifies requirements for the design, design verification and validation, manufacturing and data control, performance ratings, functional evaluations, handling and storage of tubing-deployed electrical submersible pump (ESP) systems. Additionally, this document provides requirements for assembled ESP system. This document is applicable to those ESP related components meeting the…
