Overview
IEC 61061-3-2:2001 is an international standard published by the International Electrotechnical Commission (IEC) as part of the IEC 61061 series, focusing on non-impregnated densified laminated wood for electrical purposes. Specifically, Part 3, Sheet 2, of the standard specifies the requirements for rings produced from beech veneer. These rings are widely used in electrical equipment where insulating materials must meet stringent mechanical and electrical specifications.
This standard is essential for manufacturers, designers, and quality assurance specialists involved in the production or use of insulating rings derived from densified beech veneer, ensuring their products comply with internationally recognized performance criteria. The requirements build upon the general definitions and test methods laid out in IEC 61061-1 and IEC 61061-2.
Key Topics
IEC 61061-3-2:2001 covers several important aspects, including:
- Material composition: Focus on non-impregnated, densified laminated wood made from beech veneer.
- Mechanical properties: Standards for flexural strength, compressibility, impact strength, and modulus of elasticity.
- Electrical properties: Requirements for electric strength perpendicular to the laminations and breakdown voltage parallel to the laminations.
- Dimensional tolerances: Strict controls on nominal thickness, diameter, and flatness of rings.
- Moisture and density: Maximum allowable moisture content and specified ranges for apparent density.
- Quality control measures: Specified test methods and sample preparation in accordance with IEC 61061-2.
Applications
Rings made from non-impregnated densified laminated beech veneer are utilized in a wide range of electrical equipment and systems that require robust insulation and structural performance. Practical applications include:
- Transformers and reactors: Used as insulation spacers or support rings due to their electrical insulation properties and mechanical stability.
- Electric motors and generators: Applied for insulation or as mechanical components where high dielectric strength is needed.
- Switchgear and control equipment: Incorporated in assemblies where dimensional stability, electric strength, and reliability are critical.
- Custom electrical insulating assemblies: Suitable for specialized electrical or electromechanical equipment requiring custom-shaped, robust insulating parts.
Manufacturers and designers specifying or using these rings benefit from enhanced safety, reliability, repeatable quality, and easier international sourcing thanks to standardized requirements.
Related Standards
Several related standards complement IEC 61061-3-2:2001:
- IEC 61061-1: Non-impregnated densified laminated wood for electrical purposes - Part 1: Definitions, designation, and general requirements. This serves as the foundation for material and product classification.
- IEC 61061-2: Specification for non-impregnated densified laminated wood for electrical purposes - Part 2: Methods of test. It details test methods for verifying compliance with the specified requirements.
- IEC 60243-1: Electrical strength of insulating materials - Test methods - Part 1: Tests at power frequencies. Used for determining the dielectric breakdown and insulation properties.
- Other insulating material standards: Including those for phenolic laminates or synthetic resins, which may be considered for similar applications.
Benefits of Compliance
By adhering to IEC 61061-3-2:2001, organizations ensure that their beech veneer-based laminated wood rings consistently meet established benchmarks for safety, performance, and quality in electrical insulation applications. International compliance also streamlines manufacturing processes, opens access to global markets, and reduces risk associated with material failures in service.

1) La CEI (Commission Électrotechnique Internationale) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. A cet effet, la CEI, entre autres activités, publie des Normes internationales.
Leur élaboration est confiée à des comités d'études, aux travaux desquels tout Comité national intéressé par le
sujet traité peut participer. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec la CEI, participent également aux travaux. La CEI collabore étroitement avec l'Organisation
Internationale de Normalisation (ISO), selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux intéressés
sont représentés dans chaque comité d’études.
3) Les documents produits se présentent sous la forme de recommandations internationales. Ils sont publiés
comme normes, spécifications techniques, rapports techniques ou guides et agréés comme tels par les Comités
nationaux.
4) Dans le but d'encourager l'unification internationale, les Comités nationaux de la CEI s'engagent à appliquer de
façon transparente, dans toute la mesure possible, les Normes internationales de la CEI dans leurs normes
nationales et régionales. Toute divergence entre la norme de la CEI et la norme nationale ou régionale
correspondante doit être indiquée en termes clairs dans cette dernière.
5) La CEI n’a fixé aucune procédure concernant le marquage comme indication d’approbation et sa responsabilité
n’est pas engagée quand un matériel est déclaré conforme à l’une de ses normes.
6) L’attention est attirée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour
responsable de ne pas avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this Inte
