IEC EN 60394-3-2 Epoxy for Electrical Purposes - Polyurethane - Silicone - Polyester - Bituminous and Oil Resin Varnished Fabrics

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60394-3-2 testing. IEC EN 60394-3-2 is a technical standard for varnished fabrics used for electrical purposes.

IEC EN 60394-3-2 Epoxy for Electrical Purposes - Polyurethane - Silicone - Polyester - Bituminous and Oil Resin Varnished Fabrics

This standard is one of a series for lacquered fabrics based on cotton, natural silk or synthetic fibers (including glass), supplied in full-width rolls, sheets or cut strips of various widths.

This part of the standard contains requirements for lacquered glass fabrics based on the following resins:

  • Epoxy – based on glass fabric, EP/G;
  • Polyurethane – glass fabric sole, PUR/G:
  • Silicone – glass cloth sole, SI/G;
  • Polyester – glass cloth sole, PE/G;
  • Bituminous – with glass fabric base, BT/G;
  • Oily resinous - glass-fabric based, OR/G.

The standard provides detailed guidance on the chemical composition and physical properties of each varnish used and the application process of the varnish on glass fabric. It also summarizes the mechanical and electrical properties of the obtained polished fabric.

The mechanical properties of varnished fabric include tensile strength, elongation and flexibility, which are important to ensure that the material can withstand mechanical stress and deformation. The electrical properties of lacquered fabric include dielectric strength, insulation resistance and surface resistance, which are important to ensure that the material can effectively isolate electrical components and prevent electric arc or breakdown.

In general, the specifications set out in IEC EN 60394-3-2 help ensure that various types of lacquers and glasscloth-based lacquered fabrics used in electrical applications meet certain quality and performance standards. By adhering to these standards, manufacturers can ensure that their products are safe, reliable and effective for their intended use.
