Overview
EN 60455-3-2:2003 (CLC/CENELEC adoption of IEC 60455-3-2:2003) specifies the requirements for quartz filled epoxy resinous compounds in the cured form. It applies to product types EP-F-1 to EP-F-7 and defines minimum material characteristics, referenced test methods (IEC 60455-2), and limits that support reliable electrical insulation performance. The standard also allows for introduction of other fillers in the future and contains CENELEC normative annexes.
Key Topics
- Scope and application: Requirements apply to cured quartz-filled epoxy compounds intended for electrical insulation uses. Quartz filler content is specified between 45 % and 65 % by mass.
- Referenced test methods: Measurement and verification use IEC 60455-2 methods (viscosity, epoxy equivalent, shelf life, pot life, exothermic peak, total shrinkage, and cured-state tests such as mechanical, thermal and dielectric tests).
- Typical property ranges (as given by the standard):
- Density: about 1.7–1.9 g/cm³.
- Flexural strength: minimum values across types typically range from 60 to 110 MPa.
- Tensile and impact strength: minimum tensile strengths and unnotched impact values are specified per type to support mechanical integrity under service conditions.
- Electrical and dielectric: electric strength is specified (min. 10 kV/mm), with volume resistivity, dissipation factor and permittivity limits given for each type and test temperature.
- Flammability: identified classification FH2 for the materials in cured form.
- Water absorption: low uptake required; maximum values vary by type (see Table 2 in the standard).
- Thermal performance: temperature of deflection under load and thermal endurance indices are specified to assess long-term service temperature capability.
Note: The standard provides detailed per-type requirements in Table 2. Users should consult the official text for exact numerical limits for each EP-F type.
Applications
- Procurement and specification of cast or molded insulating components in power and electrical equipment where epoxy-based, quartz-filled compounds are required.
- Quality control and type testing for insulators, potting blocks, bushings, supports and other rigid insulating parts where mechanical strength, dielectric integrity and thermal endurance are critical.
- Basis for acceptance tests in supplier contracts and for ensuring compliance with European/CENELEC requirements when selecting epoxy resin systems.

- IEC 60455-1 - Definitions and general requirements for the series (Part 1).
Compliance with EN 60455-3-2:2003 helps manufacturers, test houses and purchasers ensure that quartz-filled epoxy resinous compounds meet consistent mechanical, thermal and dielectric performance levels appropriate for electrical insulation applications.
