IEC Standards

This part of IEC 62271 is applicable to single- and three-phase direct connections between gas-insulated metal-enclosed switchgear (GIS) for rated voltages above 52 kV and transformer arrangements to establish electrical and mechanical interchange ability and to determine the limits of supply for the transformer connection. Direct connections are immersed on one end in the transformer

This part of IEC 61439 detines the specific requirements for distribution boards intended to be operaled by ordinary persons (abbrevialed DBO throughout this document, see 3.1.101) as follows: -assemblies intended to be operated by ordinary persons (e.g. switching operations and replacing fuse-links), e.g. in domestic (household) applications; – assembles containing outgoing clrcuits with protective devices

This part of IEC 61 360 specifies the new data dictionary (domain) “IEC 61 360-7 – General items” including its generic concepts. The IEC 61 360-7 data dictionary provides concepts (dictionary elements, e.g. classes, properties) intended for cross-domain use. This document has the status of a horizontal publication in accordance with IEC Guide 1 08.

This part of IEC 61 1 69, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) of HD-BNC series RF coaxial connectors together with the pro forma blank detail specification. HD-BNC series connectors with characteristic impedance of 75 Ω are used with RF cables or micro-strips in

This part of IEC 61 1 69, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for series SMB RF coaxial connectors with snap-on coupling with a characteristic impedance of 50 Ω. This document prescribes mating face dimensions for high performance connectors – grade 2,dimensional details of

This part of IEC 61 1 62 is an add-on to IEC 61 1 62-450 where higher safety and security standards are needed, for example due to higher exposure to external threats or to improve network integrity. This document provides requirements and test methods for equipment to be used in an IEC 61 1 62-460

This part of IEC 61 1 56 refers to cables as described in IEC 61 1 56-5:2020 or cables containing element(s) from cables as described in IEC 61 1 56-5 which are required to maintain both circuit integrity and data transmission capability before, during and after flame application under specified conditions. In addition to the
