Overview

EN 60893-3-5:2004/A1:2009 (identical to IEC 60893-3-5:2003/A1:2009) is a European amendment specifying requirements for industrial rigid laminated sheets based on polyester thermosetting resins used as electrical insulating materials. Published by CENELEC/IEC, the amendment updates mechanical impact limits (Charpy and Izod) based on round‑robin test results and reinforces the material property and test requirements that manufacturers, test houses and specifiers use to demonstrate conformity.

Key topics and technical requirements

This standard Part 3‑5 focuses on material‑level specifications for polyester‑based rigid laminates and references the test methods given in the IEC/EN test series. Core technical topics include:

  • Mechanical properties - flexural strength and impact resistance (Charpy or Izod). The amendment revises the impact‑strength limits for all polyester laminate types.
  • Dielectric and electrical properties - electric strength (including tests in oil at elevated temperature), breakdown voltage parallel and perpendicular to laminations, and insulation resistance after water immersion.
  • Tracking and erosion resistance - requirements and classification based on small‑scale laboratory tests (method references such as IEC 60587 are used).
  • Surface and fire behavior - flammability classification used for production consistency monitoring (not a full fire‑hazard assessment).
  • Durability metrics - water absorption limits and other conditioning‑related measurements.
  • Numeric property limits and acceptance criteria are presented in tabular form (e.g., Table 5 and related tables) in the standard; the amendment replaces Table 5 with revised property requirements.

Practical applications

This standard is intended for specifying and verifying polyester resin laminate sheets used as electrical insulation in industrial applications, for example:

  • Support and barrier components in electrical switchgear and controlgear
  • Insulating substrates and structural parts in transformers and power distribution equipment
  • Rigid insulating parts exposed to elevated temperatures, oil immersion or tracking stresses
  • Quality control and product specification for laminate manufacturers and converters

Using the standard helps ensure consistent mechanical, dielectric and tracking performance of polyester laminates under relevant electrical service conditions.

Who uses this standard

  • Laminated sheet manufacturers and compound formulators
  • Test laboratories and conformity assessment bodies
  • Electrical equipment designers, specifiers and purchasers
  • Regulatory and standards committees ensuring compliance with CENELEC/IEC norms

Related standards

  • IEC/EN 60893 series (test methods and other material parts)
  • IEC 60587 (tracking/erosion test methods)
  • Other parts of IEC 60893 addressing different resin systems and test procedures
