Gives the requirements for industrial rigid laminated sheets for electrical purposes based on phenolic resin and different reinforcements. Applications and distinguishing properties are given. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. In this revision of the IEC 60893 series of specifications, new material types have been included, changes have been made to the property requirements of some existing types, a new method for testing permittivity and dissipation factor has been added, and all non-specification data for each type has been moved to a new Part 4 document - IEC 60893-4 - Typical values.

Overview
EN 60893-3-4:2004/A1:2012 is the CENELEC/IEC standard that specifies requirements for industrial rigid laminated sheets based on phenolic (phenol) thermosetting resins used as electrical insulating materials. The amendment A1 (2012) aligns the European publication with IEC 60893-3-4:2003/A1:2012 and updates impact-strength limits based on round‑robin testing. This standard is used to classify, test and verify mechanical, electrical and climatic performance of phenolic laminates for electrical applications.
Key topics and requirements
The standard defines material-specific performance criteria and referenced test methods (see IEC 60893-2). Key technical topics include:
- Mechanical properties
- Flexural (bending) strength: minimum values specified by nominal thickness and material type.
- Impact resistance: Charpy or Izod impact strength limits; A1 revises these minimums for all phenolic laminate types.
- Electrical properties
- Electric strength (kV/mm) at 90 °C in oil and breakdown voltage parallel/perpendicular to laminations - numerical minimums are given by type and thickness.
- Insulation resistance after immersion in water (specified minimum in MΩ).
- Environmental and safety properties
- Water absorption limits (mg) based on thickness/type.
- Flammability category from small-scale lab tests (used for production consistency monitoring; not a full fire-hazard assessment).
- Test methods and classification
- Uses referenced IEC test procedures (flexural test, Charpy/Izod, dielectric tests, water immersion, flammability) and tabulates requirements by nominal thickness and laminate type.
Practical applications
This standard is directly applicable to:
- Electrical insulating components such as barriers, supports, terminal boards, mounting plates, switchgear panels, and insulating blocks.
- Manufacturers of phenolic laminated sheets seeking to certify product performance for industrial electrical use.
- Quality control and testing laboratories performing routine acceptance or type testing.
- Design engineers specifying insulating materials for transformers, switchgear, motor supports and other electrical equipment where mechanical strength, dielectric performance and environmental resistance are critical.
Who should use this standard
- Phenolic laminate producers and material suppliers
- Electrical equipment designers and OEMs
- Compliance, test-lab and procurement teams requiring assured dielectric and mechanical performance
- Standards committees and certification bodies
Related standards
- IEC 60893-3-4 and IEC 60893-2 (referenced test methods)
- Other EN/IEC parts in the EN 60893 series covering different resin systems and material families
Keywords: EN 60893-3-4, phenolic resin, rigid laminated sheets, insulating materials, electrical insulation, Charpy impact, Izod, breakdown voltage, electric strength, water absorption, flammability.
