*   Minimum Breaking Strength

The Minimum Breaking Strength (MBS) is the force that a given rope is required to meet or exceed in a laboratory test when it is new and unused. MBS values are given in Cordage Institute Standards and individual manufacturers’ specifications.

Minimum Breaking Strength (MBS) is based on tests of new and unused rope of standard construction in accordance with Cordage Institute Standard Test Methods.

There are inherent risks in the use of rope and cordage because such products are subject to highly variable conditions that change over time. Therefore, Design Factor (the ratio between the MBS and WL) selections and Working Load Limits must be calculated with consideration of exposure to risk and actual conditions of use for each application. If in doubt, consult the manufacturer, an experienced engineer or other qualified individual  regarding the design, application and selection of a rope product.

 

**     Working Load / Working Load Limit

The Working Load (WL) is the weight or force applied to rope or cordage in a given application.

The Working Load Limit (WLL) is a guideline for the maximum allowable capacity of a rope product and should not be exceeded.

Applied loads higher than a specified WLL can overstress and damage fibers, resulting in premature rope failure. The Working Load of an application should not exceed the WLL of the rope for optimalproduct performance and the safety of personnel and property.

In accordance with Cordage Institute Standard Test Methods, Working Load Limits (WLL) are for rope in good condition, with appropriate splices, in non critical applications, and under normal service conditions. As a general rule,  Working Loads Limits are 10%-15% of new rope Minimum Breaking Strength.

 

This weight, strength, size and working load chart supersedes all data and specifications sheets published prior to January 1, 2010.
