Overview

EN 60674-3-8:2011/A1:2017 (IEC 60674-3-8:2011/A1:2016) is a CENELEC/CENELEC-endorsed amendment that specifies requirements for balanced biaxially oriented polyethylene naphthalate (PEN) films used as electrical insulation. It is part of the IEC 60674 series - "Plastic films for electrical purposes" - and provides material-specific properties, test requirements and limits for PEN films intended for electrical and electrotechnical applications.

Key Topics

• Material scope: Balanced biaxially oriented PEN films for electrical insulation applications.
• Properties dependent on thickness: The amendment updates minimum electric (dielectric) strength values (V/µm) for a range of nominal film thicknesses (µm) at two temperatures (23 °C and 150 °C).
• Test methods referenced: Tests follow IEC 60674-2 procedures; the amendment includes practical test conditions such as electrode diameters and test media.
• Test environments: Electric strength values are given for testing in air, in mineral transformer oil, and in silicone transformer oil, reflecting typical service and test environments for insulating films.
• Representative minimum values (examples):
  • 16 µm: 290 V/µm (23 °C) and 230 V/µm (150 °C)
  • 100 µm: 100 V/µm (23 °C) and 80 V/µm (150 °C)
  • 250 µm: 60 V/µm (23 °C) and 40 V/µm (150 °C)
• Standards governance: Prepared by IEC TC 15 (Solid electrical insulating materials) and adopted by CENELEC; amendment ensures harmonized national standards across CENELEC members.

Applications

This standard is practical for professionals and organizations involved in:

• Insulating film manufacturers specifying PEN film performance and ensuring compliance during production.
• Transformer and capacitor designers selecting dielectric films for winding insulation and dielectric layers, especially where elevated-temperature performance is important.
• Electrical engineers and specifiers writing material specifications for high-performance insulating systems.
• Test laboratories and conformity assessment bodies conducting dielectric strength testing and type approval using IEC 60674-2 test methods.
• Procurement and quality assurance teams needing clear acceptance criteria for PEN film batches.

Related Standards

• IEC 60674-2 - Test methods for plastic insulating films (referenced for dielectric testing)
• IEC 60674 (Part 3) - Series overview: specifications for individual materials (other sheets cover PET, polypropylene, etc.)
