Insulating materials - Industrial rigid laminated sheets based on thermosetting resins for electrical purposes - Part 3-3: Specifications for individual materials - Requirements for rigid laminated sheets based on melamine resins

Gives the requirements for industrial rigid laminated sheets for electrical purposes based on melamine resins 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.

Izolacijski materiali - Industrijske toge laminirane plošče iz smol s toplotnim utrjevanjem za električne namene - 3-3. del: Specifikacije za posamezne materiale - Zahteve za toge laminirane plošče na osnovi melaminskih smol

V njem so navedene zahteve za industrijske toge laminirane plošče na osnovi melaninskih smol in različnih ojačitev za električne namene. Navedene so vrste uporab in razlikovalne lastnosti. Materiali, ki so skladni s to specifikacijo, ustrezajo določenim ravnem učinkovitosti. Vendar mora uporabnik material za specifično uporabo izbrati glede na dejanske zahteve za zadostno učinkovitost pri tej uporabi, 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 60893-3-3:2004/A1:2012 (CLC endorsement of IEC 60893-3-3:2003/A1:2011) defines technical requirements for industrial rigid laminated sheets based on melamine resins used as electrical insulating materials. This amendment (A1, 2012) updates mechanical impact limits (Charpy and Izod) and confirms European adoption by CENELEC. The standard specifies test methods, property limits and acceptance criteria to ensure consistent performance of melamine-based electrical laminates.

Key topics and requirements

• Material scope: Rigid laminated sheets manufactured from melamine (thermosetting) resins for electrical applications.
• Referenced test methods: Tests are carried out in accordance with IEC/EN test procedures (see IEC 60893-2 for test methods).
• Mechanical properties
  • Flexural strength requirements are specified for applicable sheet thicknesses.
  • Impact strength: The amendment revises limits for Charpy and Izod impact tests; the standard accepts either Charpy or Izod to demonstrate conformance.
• Electrical properties
  • Electric strength in oil at 90 °C (perpendicular to laminations) and breakdown voltage parallel to laminations are prescribed.
  • Insulation resistance after immersion in water is specified to verify long-term dielectric performance.
  • Proof tracking index requirements are given to assess surface tracking resistance.
• Fire and durability
  • Flammability: Small-scale laboratory flammability classification is included and, for these melamine laminates, the standard cites category V‑0 (for the purposes of production consistency monitoring).
  • Water absorption limits and other environmental durability checks are specified.
• Conformance: Tables of property requirements and applicable thickness ranges detail the acceptance criteria (amendment updates these tables where impact strength figures are concerned).

Applications and users

• Manufacturers of electrical laminates and melamine-based pressboards who need standardized material specifications for production control.
• Product designers and electrical engineers specifying insulating parts for switchgear, terminal blocks, terminal supports, busbar insulation, and other components requiring rigid insulating sheets.
• Test laboratories and quality control teams performing mechanical, electrical and flammability testing to verify compliance.
• Procurement, compliance and certification bodies in the EU and international markets that require harmonized standards (CENELEC/IEC) for electrical insulating materials.

Related standards

• IEC 60893 series - test methods and specifications for rigid laminated insulating materials (see IEC 60893-2 for referenced test methods).
• EN 60893-3-3:2004/A1:2012 is the CENELEC (European) adoption of the IEC text; users should consult national implementations and the CENELEC webstore for the official document.
