Fixings
Anchors Fasteners
Why load test your fixings?
​
You may have insufficient data available to determine the resistance of your post-installed anchors, or you may not have enough information about the base material.
​
In order to verify the installation quality of your post-installed anchors, you may be required to proof test them.
At Elephant we carry out on site testing to determine the maximum load the anchor can withstand (Preliminary or ultimate testing), and to prove the anchors can withstand the required load or to have a record of the installation quality (proof load testing).
Preliminary (Ultimate load) testing is carried out to determine the maximum load the fixing can withstand. This involves loading fixings until failure occurs.
Proof load testing is used to verify that fixings are sufficient for their required use. This involves applying the maximum design service load plus an additional safety factor.
