What is the breaking strain on the Adjama...

Posted on

What is the breaking strain on the Adjama Climbing Harness or the SWL? I have to document all our safety equipment and just can't find the info anywhere. Help?

Do you mean the breaking stress? Strain is defined at change in length divided by the original length. Stress is Force divided by area. However, most climbing gear is simply rated by force required to fail it, with a safety factor. Meaning they do away with the known value of area for the end users.

On the lower left of this PDF, you will see a small little diagram that says 15kN. That seems to be the best I can find for you.
