07.020 - Mathematics

This document specifies mathematical symbols, explains their meanings, and gives verbal equivalents
and applications.
This document is intended mainly for use in the natural sciences and technology, but also applies to
other areas where mathematics is used.

This International Standard provides mathematical expressions for selected reliability, availability, maintainability and maintenance support measures defined in IEC 60050192:2015. In addition, it introduces some terms not covered in IEC 60050-192:2015. They are related to aspects of the system of item classes (see hereafter).
According to IEC 60050-192:2015, dependability [192-01-22] is the ability of an item to perform as and when required and an item [192-01-01] can be an individual part, co...view more

IEC 60050-103:2009 gives the terminology relative to functions of one or more variables. Together with IEC 60050-102, it covers the mathematical terminology used in the fields of electricity, electronics and telecommunications. It maintains a clear distinction between mathematical concepts and physical concepts, even if some terms are used in both cases. Mathematical symbols are generally in accordance with IEC 60027-1 and ISO 80000-2. This standard cancels and replaces Sections 101-13, 101-14 a...view more

This part of IEC 60050 gives the general mathematical terminology used in the fields of electricity, electronics and telecommunications, together with basic concepts in linear algebra. It maintains a clear distinction between mathematical concepts and physical concepts, even if some terms are used in both cases. Another part will deal with functions.
It has the status of a horizontal standard in accordance with IEC Guide 108.
