Overview
ISO/FDIS 10325 sets out the standard requirements for high modulus polyethylene (HMPE) fibre ropes, specifically covering 8-strand braided, 12-strand braided, and covered rope constructions. Applicable to general-purpose ropes, this ISO standard provides essential rules for the designation, construction, and performance of HMPE ropes, helping ensure consistency, reliability, and safety across various industries.
This document is critical for manufacturers, users, and specifiers who need to align rope design and properties with the demands of specific applications. While ISO/FDIS 10325 includes classification and property tables for reference, it highlights the need for consultation with rope manufacturers to select the appropriate type and grade to meet operational requirements, as not all variants and performance characteristics are covered by the standard.
Key Topics
Rope Types Covered:
- 8-strand braided ropes
- 12-strand braided ropes
- Covered ropes (single braid, double braid, and multi-core options)
Material Specification:
- Ropes (or cores) made of continuous filament high modulus polyethylene (HMPE) fibres
- Covers can include polyester, polyolefins (e.g., polypropylene), or other HMPE layers
- Overlay finishes and coatings are tailored to application needs
Rope Designation:
- Clear system based on rope type, ISO reference, construction, size, material, and heat-setting status (Type 1: heat-set, Type 2: non-heat-set)
Physical Properties:
- Guidelines for linear density and minimum breaking strength of both bare and covered HMPE ropes
- Strength values serve as general-purpose reference; actual performance may vary with design
Requirements for Labelling, Packaging, and Invoicing:
- Alignment with ISO 9554 ensures traceability and correct information for end-users
Marking and Traceability:
- Use of coloured synthetic yarns and printed marker tape (as per ISO 9554) for identification and compliance
Applications
HMPE fibre ropes standardized under ISO/FDIS 10325 are recognized for their superior strength-to-weight ratio, flotation ability (for 100% HMPE ropes), and excellent abrasion resistance. Typical applications benefiting from these properties include:
- Maritime and Offshore:
Mooring lines, towing hawsers, anchoring systems, and vessel operations - Industrial Lifting and Rigging:
Lightweight, high-strength slings and winch lines - Safety and Rescue Operations:
Lines for hoisting, securing, and rapid deployment - Commercial Fishing and Aquaculture:
Nets, trawl warps, and buoy lines requiring durability and buoyancy - Construction and Utility:
Ropes for pulling, securing, or construction site logistics
Selecting the right HMPE rope type and construction is critical for optimizing performance, safety, and lifespan in these demanding sectors. Consultation with rope manufacturers is essential to address specific performance needs such as strength, creep resistance, and environmental compatibility.
Related Standards
When implementing or specifying HMPE rope products, the following related standards provide complementary guidelines for terminology, testing, and general requirements:
- ISO 1968: Fibre ropes and cordage - Vocabulary
- ISO 2307: Fibre ropes - Determination of certain physical and mechanical properties
- ISO 9554: Fibre ropes - General specifications
Complying with ISO/FDIS 10325 alongside these references ensures a unified approach to quality, performance, and safety for high modulus polyethylene fibre ropes worldwide.
For the latest updates and country-specific implementation, always consult with national standards bodies or the rope manufacturer.

general purpose use
use where a conservative approach addressing most foreseeable use, and reasonably foreseeable misuse,
provide a sufficient margin of safety against unknown variables associated with potential conditions of use.
4 Designation
Fibre ropes shall be designated as follows:
— — the words “fibre rope”;
— — the number of this document, i.e. ISO 10325;
— — the construction or type of the rope (see Clause 6Clause 6););
— — the reference number of the rope;
— — the material from which the rope is made (including cover material if applicable);
— — the type of stabilization (type 1 or type 2 in accordance with ISO 9554).
HMPE ropes that have been heat set are designated as type 1 ropes. HMPE ropes that have not been heat set
are designated as type 2 ropes.
EXAMPLE Designation of a 12-strand braided rope, reference number 20 (type T), corresponding to a linear density
of 232 ktex made of high modulus polyethylene (HMPE) that has not been heat set:
Fibre rope ISO 10325 - T - 20 - HMPE - 2
5 Material
5.1 5.1 The ropes, or load bearing core of the rope, shall be made of filament HMPE fibres. The rope
user shall consult the rope manufacturer to ensure the intended design meets the requirements of the
application.
5.2 5.2 Overlay finishes and coatings are applied on the yarn, strand or rope making ropes fit for the
intended use.
NOTE HMPE fibres have a low coefficient of friction and good abrasion resistance. The coefficient of friction can be
altered by applying suitable coatings
5.3 5.3 Concerning covered ropes, the cover may consist of a variety of fibre materials, for example,
polyester (PES), polyolefins, polypropylene (PP), high modulus polyethylene (HMPE), and may be of
varying thicknesses, depending on the requirements of the application. The type and level of protection
depends on cover construction (e.g. type of fibre(s), thickness, and applied coatings). Core constructions
may vary significantly also and incl

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en
général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit
de faire partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales
et non gouvernementales, en liaison avec l’ISO participent également aux travaux. L’ISO collabore
étroitement avec la Commission électrotechnique internationale (IEC) en ce qui concerne la
normalisation électrotechnique.

Cordages en fibres — Polyéthylène à haut module — Cordages
tressés à 8 torons, cordages tressés à 12 torons et cordages avec
couverture
1 Domaine d’application
Le présent document spécifie les exigences applicables aux cordages tressés à 8 torons, aux cordages
tressés à 12 torons et aux cordages avec couverture (cordage tressé, cordage coaxial et construction à
âmes multiples) pour usage général fabriqués en polyéthylène à haut module (HMPE), et il précise les
règles pour leur désignation.
Il existe de nombreux types et de nombreuses qualités différentes de fibres HMPE qui sont couramment
utilisés pour fabriquer des cordages. Le présent document ne couvre pas toutes les variations de
résistance ou de performance des produits. Le fabricant de cordages et l’utilisateur doivent s’accorder
afin de s’assurer que la conception du cordage est adaptée à l’usage prévu.
NOTE La sécurité d’un cordage est déterminée par le fabricant ainsi que par l’utilisateur. Un cordage est adapté
à l’usage prévu si le fabricant l’a correctement conçu, fabriqué et soumis à l’essai. Ce n’est que lorsque l’utilisateur
applique, utilise, inspecte et entretient correctement le cordage qu’un cordage adapté à l’usage prévu est réellement
adapté au service attendu.
