V njem so navedene zahteve za industrijske toge laminirane plošče na osnovi silikonskih smol in različnih ojačitev za električne namene. Navedeni so načini uporabe in razlikovalne lastnosti. Materiali, ki so skladni s to specifikacijo, ustrezajo določenim ravnem delovanja. Vendar naj bi uporabnik material za določeno uporabo izbral glede na dejanske zahteve, ki omogočajo ustrezno delovanje pri tej uporabi, in ne samo na podlagi te specifikacije. V tej različici specifikacij skupine standardov IEC 60893 so zajeti novi tipi materialov, spremenjene so zahteve glede lastnosti nekaterih obstoječih tipov, dodana sta nova metoda za preskušanje permitivnosti in faktor odvajanja, vsi podatki glede posameznih tipov, ki niso povezani s specifikacijami, pa so prestavljeni v nov, 4. del dokumenta IEC 60893-4: Običajne vrednosti.

Overview
EN IEC 60893-3-6:2004/A2:2018 specifies requirements for industrial rigid laminated sheets based on silicone resins used as electrical insulating materials. This CLC-adopted amendment (A2) updates the IEC 60893‑3‑6 series and aligns European practice with IEC requirements for material specification, testing and conformity of silicone‑resin laminates intended for electrical applications.
Key topics and technical requirements
The amendment replaces and clarifies property requirements (Table 5) and cross‑references test methods in IEC 60893‑2. Key technical topics covered include:
- Mechanical properties - evaluation of flexural strength and impact resistance (Charpy or Izod) to ensure mechanical integrity of laminates.
- Dielectric performance - electric strength (dielectric breakdown) measured at elevated temperature (90 °C) in oil, both perpendicular and parallel to laminations.
- Dielectric constants and losses - permittivity and dissipation factor measured at power frequencies (48–62 Hz) and at 1 MHz to characterise insulation behaviour across frequency ranges.
- Moisture and insulation resistance - insulation resistance after water immersion and limits on water absorption to assess long‑term electrical reliability in humid environments.
- Flammability - small‑scale laboratory flammability classification (the standard notes a V‑0 classification in test results) for production consistency monitoring.
- Material categorization - nominal sheet thickness and type groupings with associated property applicability.
Note: Amendment A2 modifies the property requirement table to reflect the updated thresholds and test applicability; detailed values and test procedures are given in the full standard and in IEC 60893‑2.
Applications and users
This standard is intended for stakeholders involved with electrical insulation materials and component manufacture, including:
- Manufacturers of silicone‑resin laminated sheets and composite insulating parts
- Electrical equipment designers and engineers specifying insulating materials for switchgear, transformers, bushings, supports and barriers
- Test laboratories and quality assurance teams performing conformance testing
- Procurement, certification bodies and standards committees ensuring compliance with IEC/CENELEC requirements
Using EN IEC 60893‑3‑6 helps ensure materials meet defined mechanical, dielectric and safety characteristics for reliable electrical insulation performance.
