What does "Ultimate tensile strength" mean?

It means the maximum load when the chain is pulled to the point of breaking.
(It is also called "Breaking strength" and "Breaking load".

Ultimate tensile strength


Test Method of Ultimate Tensile Streng

As shown in the diagram, a chain consisting of at least five links is fastened into a clamping device and arranged so that it is not subject to stresses from torsion, bending etc. It is then subjected to a gradually increasing tensile force until it breaks, at which point the maximum load is measured.

Test Method of Ultimate Tensile Streng
(Note)
1. Values resulting from failure of the clamping device are not applicable.
2. The clamping device is able to move freely.
