SIST EN ISO 10325:2026

• Abstract:

  This document specifies requirements for 8-strand braided ropes, for 12-strand braided ropes, and for covered rope constructions (single braid, double braid and multi-core construction) for general purpose made of high modulus polyethylene (HMPE), and gives rules for their designation.; Many different types and grades of HMPE fibre exist which are commonly used to produce rope products. This document does not apply to all variations in strength or product performance.

SIST EN ISO 10325:2026 is the Slovenian adoption of EN ISO 10325:2026, aligned with ISO 10325:2026. It covers general-purpose high modulus polyethylene (HMPE) fibre ropes, specifically 8-strand braided ropes, 12-strand braided ropes and covered ropes, and it sets out how to designate and identify them.

What does SIST EN ISO 10325:2026 specify?

SIST EN ISO 10325:2026 specifies the requirements for HMPE rope constructions used for general purpose applications and gives the designation rules for those ropes. It is focused on 8-strand braided ropes, 12-strand braided ropes, and covered rope constructions such as single braid, double braid and multi-core construction.

The document is organized into:

• Clause 1, Scope
• Clause 2, Normative references
• Clause 3, Terms and definitions
• Clause 4, Designation
• Clause 5, Material
• Clause 6, General requirements
• Clause 7, Physical properties
• Clause 8, Marking

The scope also makes clear that HMPE exists in many grades and performance levels, so the standard is not a catch-all for every HMPE fibre rope variant. In practice, that means a buyer or engineer should use it when the rope is a general-purpose HMPE product and the construction matches the rope types named in the standard.

What are the key requirements of SIST EN ISO 10325:2026?

SIST EN ISO 10325:2026 starts with a safety warning: rope and cordage use carries inherent risk, and compliance with the document does not by itself guarantee safe use. If the application is uncertain, the document calls for consultation with a competent person.

• Designation, Clause 4: The rope designation shall include the words “fibre rope”, the document number, the rope construction or type, the reference number, the material, and the stabilization type. This matters because the designation is the compact description used in purchase specifications, inspection records and product labels.
• Stabilization type, Clause 4: HMPE ropes that are heat set are designated as type 1, while ropes that are not heat set are type 2. This tells the user whether the rope has been thermally stabilized, which affects how the rope is identified and compared.
• Material, Clause 5: The rope, or the load-bearing core, shall be made of filament HMPE fibres. Covered ropes may use different cover materials, and the document notes that the cover can change protection and floating behavior.
• Construction, Clause 6: HMPE ropes shall be type L, type T or type K, meaning 8-strand braided, 12-strand braided or covered ropes. The construction, manufacture and braid pitch or lay length shall conform to ISO 9554, so the rope is made and described in a controlled way.
• Covered ropes, Clause 6.2: The cover is non-load-bearing, and strand interchanges in the cover are permitted if they are properly staggered. For users, that means the cover is for protection rather than strength, and construction details still need to be checked against the core design.
• Physical properties, Clause 7: Tables 1 and 2 give indicative linear density and minimum breaking strength for general purpose ropes. The values are typical only, and the standard points users to ISO 2307 for measuring linear density and for physical and mechanical property determination.
• Supplier information, Clause 5 and Clause 7: If requested, the manufacturer shall provide creep and fatigue information, and the supplier shall provide instructions for use and maintenance. This is important where the rope sees long-term loading or repeated service.
• Marking, Clause 8: The manufacturer may use coloured synthetic yarns for identification, and printed marker tape shall follow ISO 9554. This helps with traceability and product recognition in the field.

What terms does SIST EN ISO 10325:2026 define?

SIST EN ISO 10325:2026 uses a short set of terms that matter for rope selection and identification.

• HMPE: High modulus polyethylene, the fibre material used for the ropes covered by the standard.
• Cover / jacket: A braided cover or other protective layer placed over the rope core; the document notes that it does not significantly contribute to rope strength.
• Heat-set rope: A rope whose properties have been changed by applying heat while it is under controlled tensile load.
• General purpose use: Use where a conservative approach gives enough safety margin for foreseeable use and reasonably foreseeable misuse.
• Reference number: The number used with the rope designation and linked to the approximate rope diameter.
• Linear density: The mass per unit length of the rope, measured under reference tension as specified through ISO 2307.
• Minimum breaking strength: The strength value used in the tables for rope comparison and selection.

Who uses SIST EN ISO 10325:2026?

SIST EN ISO 10325:2026 is used by rope manufacturers, suppliers, buyers, quality managers, test laboratories and technical specifiers who work with HMPE fibre ropes. It is relevant whenever a team needs to choose a rope construction, write a purchase specification, check delivered marking, or compare declared physical properties with test results.

What changed in SIST EN ISO 10325:2026 from the previous edition?

SIST EN ISO 10325:2026 supersedes EN ISO 10325:2018. The main changes stated in the document are:

• a safety and risk warning was added before the Scope
• Clause 3 adds a definition of general purpose use
• Clause 5 revises the material description
• Clause 6 revises Figure 1 and aligns the figure layout
• Clause 7 revises the physical properties description and the linear density values in Tables 1 and 2, with clarified footnotes

Which standards are used with SIST EN ISO 10325:2026?

SIST EN ISO 10325:2026 cites three normative references:

• ISO 1968 - provides the vocabulary for fibre ropes and cordage
• ISO 2307 - provides the test methods for certain physical and mechanical properties, including linear density measurement
• ISO 9554 - provides general specifications for fibre ropes, including construction, manufacture, labelling, packaging, invoicing and delivered lengths

What does the SIST EN ISO 10325:2026 document contain?

SIST EN ISO 10325:2026 contains a designation system, material rules, construction requirements, property tables and marking provisions for HMPE ropes. Figures 1 to 3 show the rope constructions covered by the standard, including the two braided types and the covered-rope forms.

Tables 1 and 2 provide the indicative linear density and minimum breaking strength data used for selecting type L, type T and type K ropes. The text around those tables explains that terminations, bends, prior loading and coating can change performance in service.

The document also gives practical instructions on how rope characteristics should be described, measured and marked. For users, that supports procurement, receiving inspection, test planning and specification writing for general purpose HMPE ropes.
