Cast aluminium alloy enclosures for gas-filled high-voltage switchgear and controlgear

Cast aluminium alloy enclosures for gas-filled high-voltage switchgear and controlgear

This standard applies to cast aluminium alloy enclosures pressurized with dry air, insert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear with rated voltages above 1 kV, where the gas is used principally for its dielectric and/or arc-quanching properties. The enclosures comprise parts of electrical equipment not necessarily limited to the following examples: circuit breakers, switch-disconnectors, disconnectors, earthing switches, current transformers, voltage transformers, surge arrestors, busbars and connections. The scope also covers pressurized components such as the centre chamber of live tank switchgear, gas-insulated current transformers, etc.

Optical fibre cables - Part 1-209: Generic specification - Basic optical cable test procedures - Environmental test methods - Ageing, method F9
kSIST FprEN IEC 60794-1-209:2024

IEC 60794-1-209:2024 defines test procedures to be used in establishing uniform requirements for the environmental performance of: - optical fibre cables for use with telecommunication equipment and devices employing similar techniques; and - cables having a combination of both optical fibres and electrical conductors. Throughout this document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This document defines a test standard to determine cable aging performance by high temperature exposure and temperature cycling in order to simulate lifetime behaviour of the attenuation of cables, or physical attributes. See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements and definitions. This document partially cancels and replaces IEC 60794‑1‑22:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794‑1‑22:2017: a) the ambient temperature test condition has been defined as per IEC 60794‑1‑2; b) all the maximum allowable attenuation increase values for single-mode and multimode fibres have been deleted, and have been included in the list of details to be specified.

Electrostatics - Part 5-1: Protection of electronic devices from electrostatic phenomena - General requirements
SIST EN IEC 61340-5-1:2024

IEC 61340-5-1:2024 applies to organizations that: manufacture, process, assemble, install, package, label, service, test, inspect, transport, or otherwise handle electrical or electronic parts, assemblies and equipment with withstand voltages greater than or equal to 100 V human body model (HBM) and 200 V charge device model (CDM). Also, protection from isolated conductors is addressed by limiting the voltage on isolated conductors to less than 35 V. ESDS with lower withstand voltages can require additional control elements or adjusted limits. Processes designed to handle items that have lower ESD withstand voltage(s) can still claim compliance to this document. This document provides the requirements for an ESD control program. IEC TR 61340-5-2 provides guidance on the implementation of this document. This document does not apply to electrically initiated explosive devices, flammable liquids, gases, and powders. The purpose of this document is to provide the administrative and technical requirements for establishing, implementing, and maintaining an ESD control program (hereinafter referred to as the “program”). This edition includes the following significant technical changes with respect to the previous edition: a) definitions have been added to the document; b) updates to product qualification requirements; c) subclause 5.3.3 now includes a reference to groundable static control garment systems; d) Table 2 was replaced; e) subclause 5.3.4.2 was updated to define what an insulator is; f) subclause 5.3.4.3 was updated to include a definition for isolated conductor; g) Table 3 was updated, technical items added, including a reference to IEC 61340-5-4 for compliance verification testing; h) Table 4 was added as a summary of the requirements in IEC 61340-5-3 and to include requirements for compliance verification of packaging; i) Annex A was replaced: the former Annex is no longer required. Annex A are examples of tailoring.
