Overview
EN ISO 10556:2009 - Fibre ropes of polyester/polyolefin dual fibres - specifies requirements and designation rules for polyester/polyolefin dual-fibre ropes. The standard covers three construction types: 3‑strand hawser‑laid (type A), 8‑strand braided (type L) and 12‑strand braided (type T). It defines material requirements, yarn construction, physical properties (linear density and minimum breaking force), marking and conformity with delivery and packaging rules.
Key topics and technical requirements
- Materials
- Polyester portion: continuous multifilament, industrial (high‑tenacity), heat- and light‑resistant.
- Polyolefin portion: suitable tenacity; may be polypropylene or a mixture of polypropylene and polyethylene (PE content 15–50%).
- Yarn construction
- Cover yarns: polyester fibres over a polyolefin core, containing ≥ 40% by mass polyester.
- Interior yarns (if used) may be 100% polyolefin.
- Higher‑strength (hs) ropes: all yarns use polyester covering a polyolefin core, with ≥ 40% polyester.
- Constructions allowed
- Type A: 3‑strand hawser‑laid
- Type L: 8‑strand braided
- Type T: 12‑strand braided
- Physical properties
- Specifies linear density (ktex) and minimum breaking force (kN) across reference diameters; values apply to new, dry and wet ropes.
- Differentiates breaking force for unspliced ropes and eye‑spliced terminations.
- Linear density measured under reference tension as specified in ISO 2307.
- Designation and marking
- Designation includes: the words “fibre rope”, the standard number, rope type, reference number, materials and performance level (e.g., “(hs)”).
- Example: Fibre rope ISO 10556 - A - 20 - polyester/polyolefin (hs)
- Marking and delivery rules reference ISO 9554:2005.
- Referenced standards
Applications and users
- EN ISO 10556:2009 applies where polyester/polyolefin dual‑fibre ropes are specified for load‑bearing or handling tasks. Typical sectors and users:
- Rope and cordage manufacturers (specification and quality control)
- Procurement and engineering teams in marine, offshore, industrial lifting, towing and mooring operations
- Test laboratories and certification bodies using ISO 2307 test methods
- Specifiers drafting technical datasheets and contracts requiring consistent designation and performance data
