Hose Restraint Strength Testing by the Numbers
In industrial environments, the performance of high-pressure hoses is all about safety. As a critical safety device, hose restraints are designed to look after people and property. That’s why testing is so important.
NCG hose restraints are manufactured and tested to deliver reliable protection in the event of hose failure. To make informed decisions about the right restraint, you need to know more about how strength is measured.
What Ultimate Tensile Strength really means
Ultimate Tensile Strength (UTS) is the tested maximum load a hose restraint can withstand before failure. NCG publishes UTS ratings based on actual destructive testing, not theoretical calculations.
Testing is carried out on equipment with National Association of Testing Authorities (NATA) accreditation and calibration. That means the results are accurate, repeatable and compliant with standards.
UTS vs Aggregate Breaking Strength
When comparing hose restraints, you may also notice references to Aggregate Breaking Strength (ABS). It’s important to understand the difference.
ABS is a theoretical calculation based on the combined minimum breaking strength of individual wires – not the restraint as a complete system under load.
This is why UTS figures are always lower than ABS figures. And because it reflects real-world performance, UTS is the benchmark that really matters.
Traceability built into every restraint
Every NCG hose restraint is stamped with key identification data, including manufacturer’s logo, specific size range, individual serial number and minimum breaking load.
This information is stamped into the ferrule and printed on the heat shrink, allowing quick verification and full traceability on site.
