Full title and description

ISO 10556:2009 — Fibre ropes of polyester/polyolefin dual fibres. This International Standard specifies constructional and performance requirements, designation and marking rules for 3‑strand hawser‑laid, 8‑strand and 12‑strand braided ropes manufactured from a combination of polyester and polyolefin fibres.

Abstract

ISO 10556:2009 defines allowable constructions (Type A: 3‑strand hawser‑laid, Type L: 8‑strand braided, Type T: 12‑strand braided), compositional and yarn requirements (polyester cover over a polyolefin core; polyester content in cover ≥ 40% by mass for mixed‑fibre yarns), reference test conditions (linear density, breaking force for new/dry and wet ropes measured to ISO 2307) and rules for designation and marking.

Scope

This standard applies to fibre ropes made from polyester combined with polyolefin (polypropylene or polypropylene blended with polyethylene) in which polyester is used as a covering yarn over a polyolefin core (or equivalent dual‑fibre constructions). It covers three specific rope constructions (3‑strand hawser‑laid, 8‑strand braided, 12‑strand braided), gives minimum performance values (linear density and minimum breaking force for reference diameters) for new ropes in dry and wet conditions, and establishes designation and marking rules for delivery and identification. Test methods referenced include ISO 2307 (physical and mechanical property determination) and ISO 9554 (marking/delivery rules).

Key topics and requirements

• Permitted rope constructions: Type A (3‑strand hawser‑laid), Type L (8‑strand braided), Type T (12‑strand braided).
• Material and yarn requirements: polyester continuous multifilament as cover, polyolefin core (polypropylene or PP/PE mix where PE content is controlled); cover yarns contain ≥ 40% polyester by mass for mixed yarns.
• Performance specifications: linear density (ktex) and minimum breaking force (kN) given for reference diameters; separate values for unspliced ropes and for common spliced terminations; measurements referenced to ISO 2307 test conditions.
• Designation and marking: required designation format (including standard number, rope type, reference diameter, materials and performance level such as “(hs)” for higher‑strength variants) and delivery marking rules (reference to ISO 9554).
• Referenced documents and vocabulary: ISO 1968 (vocabulary for fibre ropes), ISO 2307 (testing), ISO 9554 (general specifications/marking).

Typical use and users

Used by rope and cordage manufacturers for product specification and quality control; procurement, engineering and fleet operations for selection of mooring, towing and handling ropes in marine, offshore and industrial applications; test laboratories and certification bodies for compliance testing; and specifiers writing tender documents and technical datasheets. The standard is often referenced alongside industry guidelines (e.g., OCIMF/MEG) and classification society requirements for synthetic hawsers and mooring lines.

FAQ

Q: What is this standard?

A: ISO 10556:2009 is an International Standard that specifies requirements, test references and designation rules for polyester/polyolefin dual‑fibre ropes in 3‑strand and multi‑strand braided constructions.

Q: What does it cover?

A: It covers rope construction types (3‑strand hawser‑laid, 8‑strand and 12‑strand braided), material/yarn composition rules (polyester cover over polyolefin core or equivalent), minimum performance values (linear density and breaking forces for new dry/wet ropes) and marking/designation for delivery. Test methods are referenced (notably ISO 2307).

Q: Who typically uses it?

A: Rope manufacturers, purchasers and engineers in marine/offshore/towing/mooring and industrial handling sectors, test laboratories, classification societies and procurement/specification teams.

Q: Is it current or superseded?

A: According to ISO, ISO 10556:2009 was reviewed and confirmed in 2020 and therefore the 2009 edition remains the current version as of that review. Users should check with the national standards body or ISO for any subsequent amendments or a new review after 2020.

Q: Is it part of a series?

A: It sits within ISO/TC 38 (Textiles) work on fibre and synthetic ropes and is used alongside related rope standards such as ISO 1968 (vocabulary), ISO 2307 (testing) and the ISO/EN polyester rope standards (ISO 1141 series). Regional adoptions exist (EN ISO 10556).

Q: What are the key keywords?

A: Fibre ropes, polyester, polyolefin, dual‑fibre, braided, hawser‑laid, breaking load, linear density, rope designation.
