(Main)Measurement of the dimensions of a cylindrical component with axial terminations
Measurement of the dimensions of a cylindrical component with axial terminations
IEC 60294:2012 applies to cylindrical capacitors and resistors for use in electronic equipment. This standard gives 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. NOTE: A measuring method for components with unidirectional terminations is given in IEC 60717. This second edition cancels and replaces the first edition, published in 1969, and constitutes a technical revision. The main technical changes with respect to the first edition are the following: - 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, - elaboration of the method for coating material extending onto wire terminations, - elaboration of the method for the overall body diameter, and - introduction of requirements on information to be given in a relevant specification.
Bestimmung der Maße eines zylindrischen Bauelementes mit axialen Anschlüssen
Mesure des dimensions d'un composant cylindrique à sorties axiales
La CEI 60294:2012 s'applique aux condensateurs et résistances cylindriques destinés à être utilisés dans les matériels électroniques. Cette norme donne des méthodes pour la mesure de la longueur du corps et pour la vérification de l'excédent de revêtement de protection sur les fils de sorties des composants à fils de sorties axiales. Elle donne également une méthode pour la vérification du diamètre hors-tout du corps des composants cylindriques à fils de sorties axiales. NOTE: Une méthode de mesure pour les composants à sorties unilatérales est donnée dans la CEI 60717. Cette deuxième édition annule et remplace la première édition parue en 1969. Elle constitue une révision technique. Les principales modifications techniques par rapport à la première édition sont les suivantes: - utilisation d'unités SI uniquement, entraînant la suppression de toutes les dimensions impériales, - réduction de la tolérance pour la profondeur du chanfrein à la Figure 1 et à la Figure 2, - élaboration de la méthode relative à l'extension du matériau de revêtement sur les fils de sorties, - élaboration de la méthode relative au diamètre hors-tout du corps, et - introduction des exigences relatives aux informations à fournir dans une spécification applicable.

MEASUREMENT OF THE DIMENSIONS
OF A CYLINDRICAL COMPONENT WITH AXIAL TERMINATIONS
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60294 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This second edition cancels and replaces the first edition, published in 1969, and constitutes
a technical revision.
The main technical changes with respect to the first edition are the following:
– 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,
– elaboration of the method for coating material extending onto wire terminations,
– elaboration of the method for the overall body diameter, and
– introduction of requirements on information to be given in a relevant specification.

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until

MEASUREMENT OF THE DIMENSIONS
OF A CYLINDRICAL COMPONENT WITH AXIAL TERMINATIONS
1 Scope
This International Standard applies to cylindrical capacitors and resistors for use in electronic
equipment.
This standard gives 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.
NOTE A measuring method for components with unidirectional terminations is given in IEC 60717.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

3 Body length
3.1 General
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 plates shall be considered sufficiently close to paraIlel if, allowing for the size of plate
and the distance between the component and the measuring device, the error in measurement
due to this cause does not exceed 0,05 mm.
Components with axial wire terminations shall be measured using the standard gauge plates
of 3.2, unless glass-metal seals or other discontinuities in the wire terminations require t
