Overview

SIST EN ISO 10325:2026 specifies the requirements for fibre ropes manufactured from high modulus polyethylene (HMPE). This standard covers three main types of rope constructions for general purpose use:

• 8-strand braided ropes
• 12-strand braided ropes
• Covered ropes (including single braid, double braid, and multi-core designs)

By defining construction parameters, material guidelines, and key performance characteristics, this standard facilitates quality assurance and consistency for HMPE rope products across multiple industries. The document also outlines the rules for the designation and marking of ropes, supporting clear identification and traceability within the supply chain.

Key Topics

SIST EN ISO 10325:2026 addresses the following essential areas:

• Material Specifications: Ropes must use continuous filament HMPE fibres in their load-bearing core. Covered ropes may use different fibres for the protective jacket according to application needs.
• Rope Constructions: Defines specific requirements for:
  • 8-strand braided ropes (Type L)
  • 12-strand braided ropes (Type T)
  • Covered ropes (Type K), which may include a single or multiple cores protected by a non-load-bearing cover
• Physical Properties: Establishes minimum values for linear density and breaking strength for both unspliced and eye-spliced terminations.
• Designation and Identification: Provides a standardized system for rope designations based on type, size, HMPE grade, and stabilization process.
• Manufacture and Labelling: Outlines requirements for construction, braid pitch, packaging, marking, and delivery lengths, as per ISO 9554.
• Testing Reference: Specifies that strength and density measurements should conform to ISO 2307 procedures.

Applications

High modulus polyethylene (HMPE) ropes standardised under SIST EN ISO 10325:2026 are chosen for their combination of high strength, low stretch, and light weight. They are widely used in applications where performance, reliability, and safety are paramount. Typical sectors and uses include:

• Maritime and Offshore Operations: Mooring lines, towing ropes, and winch lines
• Heavy Industry and Construction: Lifting slings, rigging, and load securing
• Recreational Marine: Yachting, sailing ropes, and cordage for outdoor sports
• Transport and Logistics: Container securing and cargo handling
• Utilities and Maintenance: Rope access, aerial installations, and safety lines

This standard helps manufacturers and end users align expectations for product performance, ensuring the right rope is selected for the intended service environment. Additionally, the document emphasizes that both the engineer and user play a role in ensuring rope safety and longevity through correct selection, application, and maintenance.

Related Standards

To ensure comprehensive understanding and appropriate application, SIST EN ISO 10325:2026 should be used in conjunction with related international rope and fibre standards, including:

• ISO 1968: Fibre ropes and cordage – Vocabulary
• ISO 2307: Fibre ropes – Determination of certain physical and mechanical properties
• ISO 9554: Fibre ropes – General specifications

These documents provide essential definitions, testing methodologies, and additional requirements applicable across fibre rope products.
