Calculation of the cyclic and emergency current rating of cables - Part 3: Cyclic rating factor for...
Gives a method for calculating the cyclic rating factor, for cables of all voltages, where partial drying out of the surrounding soil is anticipated. The method is based on one of the three methods published in a CIGRE document. The method is applicable to any type of cable, but it is recommended that it should be applied only to installations of one multi-core cable or to three single-core…
Calculation of load capacity of spur and helical gears — Application for industrial gears
The formulae specified in this International Standard are intended to establish a uniformly acceptable method for
calculating the pitting resistance and bending strength capacity of industrial gears with spur or helical teeth.
The rating formulae in this International Standard are not applicable to other types of gear tooth deterioration such
as plastic yielding, micropitting, scuffing, case…
Standard data element types with associated classification scheme for electric components - Part 1: ...
Provides a firm basis for the clear and unambiguous definition of
characteristic properties (data element types) of all elements of electrotechnical systems from basic components to subassemblies and full systems. Although originally conceived in the context of providing a basis for the exchange of information on electric/electronic components, the principles and methods of this standard may be…
