DIN EN 60294
Measurement of the dimensions of a cylindrical component with axial terminations (IEC 60294:2012); German version EN 60294:2012
Bestimmung der Maße eines zylindrischen Bauelementes mit axialen Anschlüssen (IEC 60294:2012); Deutsche Fassung EN 60294:2012
Overview
This International Standard applies to cylindrical capacitors and resistors for use in electronic equipment. It specifies methods for measurement of the body length and for checking the excessive protective coating extending onto the wire terminations of components with axial wire terminations. It further provides a method for checking the overall body diameter of cylindrical components with axial wire terminations. A measuring method for components with unidirectional terminations is given in IEC 60717. The length of the body shall be measured by inserting the wire terminations into slots or bores of a pair of gauge plates and by moving these plates parallel to each other until the component body is clamped without deforming the body or the wire terminations. The following figure describes the standard gauge plates. The following modifications have been made with respect to the first edition of DIN IEC 60294:1986-01: - employment of SI units only, causing deletion of all imperial dimensions; - reduction of the tolerance on the chamfer depth in Figure 1 and Figure 2; - description of the method for checking the coating material extending onto wire terminations; - description of the method for determination of largest body diameter; - introduction of information required to be given in a relevant specification. The responsible committee is GK 613 "Widerstände" ("Resistors") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
