How much should the deviation between applied force and measured elongation not exceed during tensioning?

The standard for the acceptable deviation between applied force and measured elongation during tensioning is established to ensure accuracy and safety in the tensioning process. A deviation of 5% indicates a balance between allowable variations and the need for precision. This level of deviation ensures that any adjustments made during tensioning maintain structural integrity and the desired pre-stress in the materials involved.

Maintaining an upper threshold of 5% allows for operational flexibility while still adhering to industry safety standards. Straying beyond this percentage could lead to inadequate tensioning or over-tensioning, both of which can compromise the performance of the structural element being tensioned. Hence, a 5% deviation threshold strikes an optimal balance, ensuring that tensioning processes are reliable and effective.
