This feature ensures that pet leashes maintain their hold even when subjected to the maximum physical force of large or reactive animals, providing a benchmark for high-performance functionality.
The Science of Tensile Load and Peak Force
In the pet industry, leash strength is a measure of "ultimate tensile capacity" and "component synergy." A leash is only as strong as its weakest point, which is typically the swivel eye of the bolt snap or the "box-stitch" joining the handle to the lead. High-performance leashes are engineered using high-tenacity nylon or polyester webbing and "Climbing Grade" carabiners or heavy-duty zinc-alloy clasps. This engineering ensures that the leash can absorb the kinetic energy of a dog in motion—which can exert a force several times its own body weight—without the fibers reaching their breaking point or the metal hardware deforming.
Validation through the High Performance Mark
By meeting rigorous technical benchmarks, your pet leashes become eligible for the Intertek High Performance (HP) Mark’s Strength. For this mark, we apply our unique in-house test method ITS M 0082, which utilizes specially designed test equipment to apply the appropriate pull force to simulate actual use, up to 66.9kg for the largest pets. The product must withstand the testing without damage or breakage.
This mark serves as a ‘proof of performance’ by validating that your product meets the HP Mark standards for safety across specific dog sizes. You can display the mark on product packaging, retail hangtags, and digital storefronts to confidently signal to pet owners that their "lifeline" to their pet is verified for maximum security.
