Radio interference characteristics of overhead power lines and high-voltage equipment. Part 3: Code ...
This publication forms a "a code of good practice" to reduce to a
minimum the production of radio noise by power lines and equipment.
It provides information to follow both when
designing various fittings and components and when stringing the
conductors and installing the hardware of the line.
It also describes methods of detecting and locating defects
resulting in unusually high…
Flickermeter - Functional and design specifications
This report gives a functional and design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Sufficient information is presented to enable such an instrument to be constructed.
It does not specify the method of calculating a flicker severity value, or give tolerable limit values.
Software for computers in the safety systems of nuclear power stations
Applies to highly reliable software required for computers to be used in the safety systems of nuclear plants for safety functions (Class 1 functions according to IEC 643). This includes the safety actuation systems, the safety system support features and the protection systems. This standard provides requirements for each stage of software generation, including design, development, qualification…
