Overview

EN 60811-508:2012/A1:2017 (IEC 60811-508:2012/A1:2017) is the CENELEC amendment specifying a mechanical pressure test at high temperature for non‑metallic insulation and sheaths used on electric and optical fibre cables. It amends and clarifies test apparatus, specimen preparation, measurement procedures and the formulae used to determine the minimum blade force applied during the high‑temperature indentation/pressure test.

Keywords: EN 60811-508:2012/A1:2017, IEC 60811-508, pressure test at high temperature, insulation and sheaths, cable test methods, non‑metallic materials.

Key topics and technical requirements

• Scope and status: European endorsement of IEC 60811-508 with amendment A1 (approved 2017); national implementation dates and CENELEC compliance noted.
• Test environment (air oven): Includes a new NOTE warning that thermoplastic materials with sharp melting points (e.g., some ethylene polymers) can show large increases in indentation with small temperature rises above the test temperature.
• Indentation device: Clarified requirement for an indentation blade with a flat edge (replacement of previous wording).
• Measurement equipment and precision:
  • Strip shall be measured using a measuring microscope, measuring projector, or optical digital image analyser with at least 10× magnification.
  • Cross‑wire alignment to the bottom of the indentation and outside of the test piece; microscope is the reference method in case of doubt.
  • Use a reading resolution of 0.01 mm, and for insulation thickness < 0.7 mm provide estimated readings to three decimal places.
• Specimen preparation: Clarifications for sheath test piece preparation (terminology change from “Insulation” to “Sheath” in notes).
• Force determination:
  • The standard defines a formula for the minimum blade force F as a function of a coefficient k, the measured thickness δ, and a mean diameter parameter D.
  • If not otherwise specified in a product standard, default k values are provided (general values: 0.6 and 0.7, with application rules listed, and distinctions for flexible vs fixed installation cables and D ≤ 15 mm or > 15 mm).
  • Special rules for flat cables and multi‑core arrangements (e.g., twin core) modify the applied force (multiplication factors described).

Applications and users

• Cable manufacturers (design verification and production quality control)
• Independent testing laboratories and certification bodies
• Materials engineers evaluating polymeric insulation and sheath performance at elevated temperature and pressure
• Spec writers and purchasers requiring standardized mechanical ageing/durability data for cable selection

Practical benefits: ensures repeatable, comparable results for cable mechanical high‑temperature pressure testing, informs material selection, supports compliance and product specifications.

Related standards

• IEC/EN 60811 series (test methods for non‑metallic materials used in cables)
• Refer to the base publication EN 60811-508:2012 and the international IEC 60811-508:2012/A1:2017 for full test details and figures.
