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 TR 63434:2023 is intended to provide awareness about partial discharge phenomena. This document gives guidance for some conditions when partial discharge can occur in low voltage switchgear and controlgear connected to networks of up to 1 000 V AC. Internal operational voltages can exceed these values. This document gives guidance on the design of conductors and dimensioning of insulation…

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.…

IEC 61936-2:2023 provides, in a convenient form, requirements for the design and the erection of DC installations in systems with nominal voltages above 1,5 kV DC, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this document, a DC installation is considered to be one of the following: a) A converter station or DC switching station; b) one (…

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.

IEC 61010-2-030:2023 specifies safety requirements for equipment having testing or measuring circuits which are connected for test or measurement purposes to devices or circuits outside the measurement equipment itself. These include measuring circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. These circuits in equipment have…

IEC 61010-2-030:2023 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with the comprehensive content of the Standard. IEC 61010-2-030:2023 EXV includes the content of the references made to IEC 61010-1:2010 and IEC 61010-1:2010/AMD1:2016. IEC 61010-2-030:2023 EXV…

IEC TS 63266:2023 specifies a structure for representation of exchanged information that is essential for testing and maintenance of the devices in power utility automation systems. It is mainly intended to be applied to communication equipment that communicate information in accordance with IEC 61850 (all parts) in at least one part of their communication flow. The following communication…

This document specifies the measurement of forces by means of load cells carried out for geotechnical monitoring. General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674-1. This document is applicable to: —     performance monitoring of geotechnical structures such as anchors,…
