Overview

EN 60811-201:2012 (IEC 60811-201:2012) specifies standardized methods for the measurement of insulation thickness of non-metallic materials used in electric and optical fibre cables. It covers common insulating compounds (cross-linked polymers, PVC, PE, PP, etc.) and is intended to be used together with EN/IEC 60811‑100 (general provisions). This part replaces clause 8.1 of the earlier IEC 60811‑1‑1 and is adopted by CENELEC/CLC for harmonized European use.

Key topics and requirements

• Scope: Methods apply to insulation thickness measurement for most cable insulating compounds; tests normally at room temperature.
• Measuring equipment:
  • Measuring microscope or profile projector with at least 10× magnification or an optical digital image analyser.
  • Equipment must allow readings to 0.01 mm, and three decimal places for specified thicknesses < 0.5 mm.
  • Measuring microscope is the reference method if in doubt.
• Sample preparation:
  • Remove outer coverings and withdraw conductor(s) without damaging insulation; bonded semi-conducting layers must remain.
  • Cut a thin slice perpendicular to the conductor axis; for flat non-sheathed cores do not separate cores.
  • If the insulation has indented marking (local thickness reduction), include the marking in sample selection but exclude it from mean-thickness calculations unless specified.
• Measuring procedure:
  • Typically six radial measurements (e.g., at ~60° intervals) for circular or stranded conductors; specific measurement patterns apply for sectoral, uneven or flat profiles (figures provided in the standard).
  • Exclude unremovable screening layers from the measurement; use a measuring microscope for opaque insulations with such layers.
  • First measurement must be taken at the thinnest point.
• Reporting and evaluation:
  • Report in accordance with IEC 60811‑100 and include measuring equipment specifications.
  • Readings: two decimal places for thickness ≥ 0.5 mm, three estimated decimals for < 0.5 mm.
  • Result evaluation follows the relevant cable standard’s acceptance criteria.

Applications and users

• Who uses it: cable manufacturers, independent test laboratories, material suppliers, R&D and quality assurance teams, and standards bodies.
• Practical uses: incoming material inspection, production quality control, acceptance testing, and as part of mechanical or electrical tests where correct insulation thickness affects performance and safety (e.g., dielectric strength, mechanical protection).

Related standards

• EN/IEC 60811‑100 (general rules and reporting) - mandatory companion document.
• IEC 60811 series - other parts cover additional non-metallic material test methods.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
