Cargo Net Testing Definitions to determine Product Load Ratings
The strength of cargo nets is commonly determined by two separate testing methods to determine the product load ratings:
- Weakest Component Break Test – Test conducted by using a calibrated hydraulic ram to break each component systematically in a controlled environment.
- Complete Assembly Break Test – Test conducted by stressing all components equally until failure point. For this test the break limit is determined on complete assembly.
Break Limit: This number is determined by the amount of tension, pressure or weight it takes to “break” any component or the complete assembly of the tested subject.
Safety Factor: To determine the Working Load Limit (WLL) rating of a cargo net, sling or tie down, a Safety Factor is used. This number is set by the industry and is divided into the break limit of the product. Three is the industry standard Safety Factor for rating a cargo net, sling or tie down.
Break Limit ÷ 3 = Working Load Limit (WLL)
A Safety Factor of 3 is the standard for complying to NSC 10 legislation and the industry standard for rating a cargo net, sling or tie down.
