    Abstract - (Show below) - (Hide below)

    IEC 60393-1:2008 is applicable to all types of resistive potentiometers, including lead- screw actuated types, presets, multi-turn units, etc., to be used in electronic equipment. It establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications of electronic components for quality assessment or any other purpose. It has been mainly written, and the test methods described, to conform to the widely used single-turn rotary potentiometer with an operating shaft. This edition contains the following significant technical changes with respect to the previous edition: implementation of Annex H which replaces Section 3 of the previous edition. It also includes minor revisions related to tables, figures and references.
