Pull Test  We realize that the strength of our web is very important for our customers.

  

  • Testing at Boss Strapping
    An Important part of our manufacturing process is the pull testing of our strapping to ensure:
    1) the quality of the yarn
    2) the consistency of the weave
    3) the strength of the strap

    There are two primary pull tests conducted on woven narrow fabric (straps); break strength and system strength.


     
  • Break Test Strength
    As the name implies, with this test the strap (alone) is pulled until it breaks.
    This is also referred to as the Tensile Strength.

    This tests the strength of the strap only.  At BOSS our typical Break Strength for our 1 ½” strap = 5,175 lbs.







     
  • System Break Strength
    This tests the complete strap system; both the strap and the buckle are pulled until failure.

    The system break strength is almost always more than the break strength. Also, the strap will normally break before the buckle.  At BOSS our typical System Break Strength for our 1 ½” strap and Buckle = 5,650 lbs
