What is ISO 1140 about?
ISO 1140 specifies requirements for 3-strand hawser-laid and 4-strand shroud-laid ropes, 8-strand braided ropes, and 12-strand braided ropes for general service made of polyamide, and gives rules for their designation.
NOTE: ISO 1140 does not cover all variations in the strength or product performance. The rope manufacturer is consulted to ensure the intended design meets the requirements of the application.
Who is ISO 1140 for?
ISO 1140 on designation of fibre ropes is relevant to:
- Polyamide fibre ropes manufacturer
- Industrial applications
- Rigging and construction industry
Why should you use ISO 1140?
Polyamide is the most widely used fibre for making high-quality ropes from synthetic material.
ISO 1140 states the designation of different kinds of polyamide ropes that ensures of abrasion-resistant, highly-durable and elastic product.
ISO 1140 also provides the necessary procedures to determine dimensional stability, linear density and minimum breaking strength (MBS). However, the MBS can set by each manufacturer, as per their own internal statistical methods based on breaking tests.
What’s changed since the last update?
ISO 1140:2021 supersedes ISO 1140:2012. ISO 1140:2021 includes some technical changes with respect to ISO 1140:2012. These include:
- In the Scope, a statement specifying that the document does not cover all variations in strength or product performance has been added
- The term "minimum breaking strength" has been added
- The tolerances in linear density have been modified
