Resistor Standards
US and international standards for electronic components, capacitors, transducers, surge protectors, LEDs, and resistors find wide application in consumer products, vehicles, medical devices, sensors and controls for industrial use and more. A representative selection of nearly one hundred standards published in recent years covering electronic components are provided here. For even more electronic component standards search by keyword in the field above or browse the offerings of the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE), two standard developing organizations focused on electronics and their design, manufacture, testing, use, and end-of-life procedures. These packages include many standards related to construction and specification of electric resistors.

IEC 60440 Ed. 1.0 b:2012
Method of measurement of non-linearity in resistors
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.
