Defines a method of measurement and associated test conditions to assess the magnitude of non-linear distortion generated in a resistor.

IEC 60440:2012 specifies a method of measurement and associated test conditions to assess the magnitude of non-linear distortion generated in a resistor. This method is applied if prescribed by a relevant component specification, or if agreed between a customer and a manufacturer. This International Standard cancels and replaces the Technical Report IEC/TR 60440, published in 1973. The major changes with regard to the Technical Report are:
- change of the principle parameter\'s term from \'third harmonic attenuation\' to \'third harmonic ratio\';
- addition of advice on the prescription of requirements in a relevant component specification;
- addition of a set of recommended measuring conditions for a specimen with a rated dissipation of less than 100 mW;
- a complete editorial revision.
