Overview

EN 61628-1:1997 (CLC adoption of IEC 61628-1:1997) establishes the definitions, designations and general requirements for corrugated pressboard and presspaper used in electrical applications. The part sets out terminology, designation coding and fundamental supply, marking and composition requirements to support consistent, reliable use of these insulating materials. The standard emphasizes that material selection must be based on the actual application requirements rather than the specification alone.

Key Topics

• Scope and purpose: Defines corrugated pressboard and presspaper for electrical purposes and provides the framework for classification and basic requirements.
• Corrugation types: Describes corrugation forms used in sheet materials, including:
  • symmetrical sine type
  • symmetrical angular type
  • non-symmetrical sine type
  • non-symmetrical angular type
• Designation system: Specifies a designation format combining base material type, thickness and corrugation code. Example: B3.1/1/SS denotes a B3.1 base material, 1 mm thickness, symmetrical sine corrugation.
• General requirements:
  • Composition: materials shall be manufactured from pressboard or presspaper in accordance with IEC 60641-1 and formed by mechanical pressure, heat or moisture or a combination, without additives.
  • Packaging: supply packaging must protect the material during handling, transport and storage.
  • Marking: consignments must be legibly marked with an identifiable code; marking materials must be electrically neutral, oil resistant and non-polluting to oil.
• Selection guidance: The standard notes materials conforming to this part meet established performance levels but stresses selecting materials based on specific application needs.

Applications

EN 61628-1:1997 is directly relevant to manufacturers, specifiers and design engineers dealing with electrical insulation systems where corrugated pressboard or presspaper are considered. Typical applications include:

• internal insulation components in transformers and switchgear
• insulating spacers, barriers and support structures
• components where controlled mechanical form (corrugation) contributes to dielectric or mechanical performance

The standard supports consistent procurement, quality control and interchangeability between suppliers by clarifying terminology and marking.

Related Standards

• IEC 61628 series: Part 2 (methods of test) and Part 3 (material specifications) are related and provide test methods and detailed specifications.
• IEC 60641-1, IEC 60641-2 and IEC 60641-3-x: referenced normative documents for pressboard/presspaper definitions, tests and material sheets.

For specification and compliance, consult the full EN/IEC text and applicable national adoptions. EN 61628-1:1997 provides the normative framework to ensure consistent quality, clear designation and safe supply of corrugated insulating materials.

61628-1 © IEC:1997– 3 –INTERNATIONAL ELECTROTECHNICAL COMMISSION–––––––––––CORRUGATED PRESSBOARD AND PRESSPAPERFOR ELECTRICAL PURPOSES –Part 1: Definitions, designations andgeneral requirementsFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, 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 InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61628-1 has been prepared by subcommittee 15C: Specifications,of IEC technical committee 15: Insulating materials.The text of this standard is based on the following documents:FDISReport on voting15C/796/FDIS15C/844/RVDFull information on the voting for the approval of this standard can be found
