Standards

This standard specifies requirements for gas-insulated, metal-enclosed switchgear in which the insulation is obtained, at least partly , by an insulting gas other than air at atmospheric pressure, for alternating current of rated voltage above 52 kV, for indoor and outdoor installation, and for services frequencies up to and including 60 Hz.

This technical report applies to high -voltage switchgear and control gear such as circuit breakers, disconnectors and switches. However , its application to other equipment is not excluded . The terminals can be made of any suitable materials; no coordination between dimensions and the rated normal current can be given.

This technical report contains information and test procedures for type testing of circuit- breakers relevant to short-circuit breaking performances during asymmetrical test duty (t100a) as required by IEC 62271-100.

This technical report is applicable to class E2 circuit-breakers rated 72,5 kV and above intended for use on overhead tines.

This technical report applies to medical electrical equipment (as declined in subclauses 3.63 of IEC 60601 -1 2005 and 2.2 15 IEC 60601-1 : 1988) hereinafter referred to as me equipment.

This clause of Part 1 is replaced by the following. This International standard deals with the safety of electric fans for household and similar purposes, their rated voltage being not more than 250V for single-phase appliances and 480 V for other appliances.

This part of IEC 61400 deals with mechanical load measurements on wind turbines . It mainly focuses on large (.40 m2 electricity generating horizontal axis wind turbines. However, the methods described might be applicable to other wind turbines as well for example, mechanical water pumpers, vertical axis turbines.

This technical report introduces the concept of functional safety and gives an overview of the IEC 61508 series.

This technical specification provides design, testing and loading information for uses by both the manufacturer and user of liquid-immersed power transformers using either high temperature insulation or combination of high-temperature and conventional insulation. It is application to power transformers designed in accordance with IEC 60076-1. - - convertor transformers designed to IEC 61378. - arc furnace transformers. and covers the use of various liquid and solid insulation combinations..

This document establishes requirements and provides guidelines for subsurface safety valve (SSSV) system equipment. This includes requirements for SSSV system design, installation, operation, testing, redress, support activities, documentation, and failure reporting. SSSV system equipment addressed by this document includes control systems, control lines, SSSVs, and secondary tools as defined herein. SSSV types including surface controlled (SCSSV), sub-surface controlled (SSCSV), and sub-surface injection safety valves (SSISV) are included. Requirements for testing of SSSVs including frequency and acceptance criteria are included. Alternate technology SSSV equipment and systems are included in these requirements. This document is not applicable to design, qualification, or repair activities for SSSVs. This document does not specify when a SSSV is required.
