In stock
Description
Capacity 1000 kN
Material Mild Steel
Test Method IS 1367 (Part - 3), IS1367 (Part -6)
A Proof Load Test for bolts and nuts verifies a fastener's structural integrity by applying a predetermined load, usually 70-80% of its minimum ultimate tensile strength, to ensure it withstands working loads without permanent deformation or failure. The test involves securing the component in a tensile machine, applying the specified load for a set time, and then checking for any measurable permanent change in length or signs of damage. A successful test demonstrates that the bolt or nut is safe and reliable for its intended use.
