ISO 2307:2019 — Fibre ropes — Determination of certain physical and mechanical properties
ISO 2307 is an ISO International Standard that describes methods for determining several commonly specified rope characteristics used in manufacturing control, purchasing specifications, and performance verification.
It is typically referenced alongside a rope product specification (or customer requirement) to define how properties like diameter, elongation, and breaking force are measured in a consistent way.
Quick Definition
ISO 2307 is a rope-testing standard focused on measuring fibre rope geometry and performance, including breaking force and elongation, plus selected optional finish-related checks when requested.
What This Standard Covers
ISO 2307 provides methods to determine physical characteristics and tensile-performance characteristics for fibre ropes.
| Characteristic measured | What it supports |
|---|---|
| Linear density | Mass-per-length verification for ordering and product control |
| Diameter | Fit, compatibility, and conformance to specified size |
| Lay length / braid pitch | Construction and manufacturing consistency checks |
| Elongation | Stretch behavior reporting for quality and application suitability |
| Breaking force | Strength verification against purchase/specification requirements |
When requested by a customer, ISO 2307 also includes methods to measure water repellence, lubrication, and finish content.
Why This Standard Matters in Testing
Fibre ropes are sensitive to construction, handling, and gripping method during testing. ISO 2307 helps reduce disputes by defining how key properties are measured and reported under controlled conditions.
For labs and QA/QC teams, the biggest practical impact is repeatability: consistent pre-tensioning/measurement approach for geometry checks and a consistent tensile test approach for breaking force and elongation.
Common Materials, Product Types, or Applications Covered
This standard is used for fibre ropes across industrial and commercial supply chains where a measurable conformance requirement exists (diameter, mass-per-length, elongation, and strength).
Common examples: General-purpose fibre ropes, braided or laid constructions, and customer-specified ropes where proof of properties is needed for purchasing, safety margins, or process control.
Common Test or Verification Workflow
ISO 2307 is commonly used as part of a receiving inspection, production QA, or qualification workflow for rope products.
Typical workflow: Condition and identify rope sample → measure linear density and diameter → measure construction parameters (lay length / braid pitch) as applicable → perform tensile test to determine breaking force and elongation → document results versus the cited product requirement.
Optional finish-related checks (water repellence, lubrication, finish content) may be added when required by the purchase order or contract specification.
Equipment Commonly Used for This Standard
Equipment selection for ISO 2307 is driven primarily by maximum breaking force, rope diameter range, and how the rope must be gripped without premature slip or localized damage.
Common equipment: Universal testing machine or dedicated rope tensile tester (appropriate force range), calibrated load cell, rope grips (selected to suit diameter and construction), and a safe test area or guarding for recoil at failure.
Common measuring tools: Devices for mass-per-length and dimensional checks (for example, a balance for linear density determination and suitable tools for diameter and construction measurements).
If you are comparing machine capacities or grip packages for larger diameters or higher loads, you can request a detailed quote for an equipment configuration matched to your rope range and target forces.
How to Read This Designation or Revision
ISO standards are commonly cited using the format “ISO 2307:YYYY”, where “YYYY” indicates the publication year of the referenced edition.
Because acceptance criteria are usually defined in a separate rope specification or customer requirement, it is important that your test report states the exact ISO 2307 edition used, along with the rope identification and the reported properties (for example, diameter, elongation, and breaking force).
Related Standards, Methods, or Frameworks
ISO 2307 is often referenced by fibre rope product specifications and procurement documents to define how declared properties are determined. Those companion documents typically define the required minimum values, while ISO 2307 defines the measurement approach.
When you are working to a contract specification, keep the full chain aligned: rope type and construction definition, the cited ISO 2307 edition, and the required acceptance limits for each reported property.
