Overview

EN ISO 1140:2021 (ISO 1140:2021) specifies requirements for polyamide fibre ropes in common constructions: 3‑strand hawser‑laid, 4‑strand shroud‑laid, 8‑strand braided and 12‑strand braided ropes intended for general service. The standard covers designation rules, construction and manufacture requirements, physical properties (linear density and minimum breaking strength, MBS), marking and delivery. It supersedes EN ISO 1140:2012 and works alongside other rope standards for testing and vocabulary.

Key topics and technical requirements

  • Constructions covered:
    • Type A = 3‑strand hawser‑laid
    • Type B = 4‑strand shroud‑laid
    • Type L = 8‑strand braided
    • Type T = 12‑strand braided
  • Designation rules: ropes are designated using “Fibre rope”, the standard number (ISO 1140), construction/type, reference number (approximate diameter), material (PA = polyamide) and stabilization type (1 = heat‑set, 2 = not heat‑set). Example: Fibre rope ISO 1140 – A – 20 – PA – 1.
  • Physical properties: linear density (ktex) and minimum breaking strength (MBS) values are specified in tables for each construction and reference number. Linear density is measured under reference tension per ISO 2307. MBS relates to new dry ropes; wet breaking strength is typically 10–20% lower and ropes must be fully immersed 24 h before wet testing.
  • Terminations and strength: the tables provide different MBS values for unspliced ropes and ropes with eye‑spliced terminations (splices reduce MBS compared with unspliced).
  • Marking: Type 1 ropes with reference number < 14 shall be marked with a green thread; other marking follows ISO 9554.
  • Limitations: the standard states it does not cover all variations in strength or product performance - manufacturers must be consulted to ensure a rope design meets specific application requirements.
  • Testing & referenced methods: testing and terminology references include ISO 2307 (physical/mechanical tests), ISO 9554 (general rope specs) and ISO 1968 (vocabulary).

Applications and users

EN ISO 1140:2021 is used to:

  • Specify and buy polyamide ropes with clear designation, expected linear density and minimum breaking strength for general service.
  • Provide manufacturers, specifiers and testing laboratories with standardized MBS and linear density requirements.
  • Assist engineers, procurement teams and quality managers to compare rope types (3‑, 4‑, 8‑ and 12‑strand) and ensure consistent marking, packaging and delivery.

Typical stakeholders: rope manufacturers, textile and rope testing labs, procurement/specification engineers, and any organisation requiring standardized polyamide rope data for general service applications.

Related standards

  • ISO 2307 - Fibre ropes: determination of certain physical and mechanical properties (testing methods)
  • ISO 9554 - Fibre ropes: general specifications
  • ISO 1968 - Fibre ropes and cordage: vocabulary

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
