Standards

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 part of the ISO/IEC 9314 specifies the Media access control (MAC) the middle sublayer of the data link layer (DLL) for fiber distributed data interface (FDD). FDDI (ISO/IEC 9314) provides a high- bandwidth (100 Mbits) general - purpose interconnection among information processing systems, subsystems and peripheral equipment, using fiber optics or other transmission media. (FDDI can be configured to support a sustained data transfer rate of at least 80 Mbits/s (10 Mbyte/s). FDDI provides connectively for many nodes distributed over distances of many kilometers in extent. Certain default parameter values for FDDI (eg. timer settings) are calculated on the basis of up to 1000 transmission links or up to 200 km total fiber path length (typically corresponding to 500 nodes and 100 km of dual fiber cable, respectively) however, the FDDI protocols can support much larger networks by increasing these parameter values.

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 International standard defines an input/output bus for interconnecting computers and peripheral devices. It defines extensions to the small computer system interface (ISO 9316:1989), referred to herein to herein as SCSI-1. Its also provides more complete standardization of the previously characteristics of the interface to allow inter-operability of conforming devices. This International standards is referred to herein as SCS1-2. The term SCS1 is used wherever it is not necessary between the two version
