Letter symbols to be used in electrical technology - Part 3: Logarithmic and related quantities, and their units
   Abstract
Applies to logarithmic quantities and units. Quantities that can be expressed as the logarithm of a dimensionless quantity, such as the ratio of two physical quantities of the same kind, can be regarded and treated in different ways. In many cases, differences do not affect practical treatment.

Letter symbols to be used in electrical technology - Part 7: Power generation, transmission and distribution
   Abstract
IEC 60027-7:2010 is applicable to generation, transmission, and distribution of electric energy. It gives names and letter symbols for quantities and units. In addition, rules for multiple subscripts and their succession are given. It is an addition to IEC 60027-1. Therefore letter symbols already given in IEC 60027-1 are repeated only if they have a special meaning in the field of power generation, transmission, and distribution or if they are used in this field with special subscripts.

Rotating electrical machines - Part 1: Rating and performance
   Abstract
IEC 60034-1:2010 is applicable to all rotating electrical machines except those covered by other IEC standards, for example, IEC 60349. Machines within the scope of this standard may also be subject to superseding, modifying or additional requirements in other publications, for example, IEC 60079 and IEC 60092. The changes with respect to the previous edition are as follows:

- clarification of water coolant temperature,

- recognition of IE code,

- clarification of the term "tolerances".
