Overview
EN 60371-3-7:1995/A1:2006 (IEC 60371-3-7:1995/A1:2006) specifies requirements for polyester film mica paper with an epoxy resin binder intended for single conductor taping in electrical insulation. This amendment (A1, approved 2006-10-01) updates test references, designation rules and specific performance limits. The sheet forms part of the IEC 60371 series that governs insulating materials based on mica.
This standard is primarily used by manufacturers, quality engineers and specifiers of conductor insulation materials to ensure material compliance, reliable performance and interchangeability across CENELEC member states.
Key Topics
- Designation and ordering: Materials are ordered by the specification and type number (example: IEC 60371-3-7: type 7.1.01). The type number derives from the sheet number, table number and product entry.
- Constituent materials: Mica paper shall comply with IEC 60371-3-2. Polyester backing films must be PET meeting IEC 60674-3-2 requirements.
- Composition and tolerances: Composition limits are verified by methods referenced in IEC 60371-2 (Clause 7) and supplied in the sheet tables.
- Thickness measurement: Thickness is measured per Clause 4 of IEC 60371-2, taking 10 measurements to characterise the material.
- Mechanical and electrical performance:
- Electric strength: Minimum specified value when tested per Clause 16 of IEC 60371-2 with electrodes per IEC 60243-1 is not less than 50 kV/mm.
- Tensile strength: When tested per Clause 8 of IEC 60371-2, minimum tensile strengths are specified for film thicknesses: ≥ 25 N/10 mm for 23 µm film and ≥ 40 N/10 mm for 30 µm film.
- Stiffness testing: Per Clause 11 of IEC 60371-2 when stiffness is a specified requirement.
Applications
This sheet targets use in single-conductor taping where a combination of mica-based dielectric performance and a polyester (PET) support film are required. Typical applications include:
- Insulation layers or tapes for coils, windings and high-temperature electrical assemblies
- Situations requiring high dielectric strength and controlled tensile performance
- Environments where standardized material designation and interchangeability are needed across manufacturers
Benefits include improved dielectric reliability, predictable mechanical properties and harmonised test methods for quality control.
