From Wikipedia, the free encyclopedia. Retrieved from ” https: However lec document allows an easy reference whereby the standard conductor sizes and reference to physical dimensions are maintained but given an exact meaning in terms of the electrical characteristics of a conductor.

This 600028 a key distinction as it makes a standardized definition of conductors based solely on their electrical characteristics. This document is one considered Fundamental in that it does not contain reference to any other standard. By using this site, you agree to the Terms of Use and Privacy Policy.

International standard of resistance for copper Article no: Views Read Edit View history. This page was last edited on 16 Novemberat The current version is Third Edition [1] Among other things, it defines a set of standard wire cross-sectional areas:.

Sustainable Development Goals and standardisation, how do they connect? In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance.
