Pullout Test

Last updated: June 1, 2018

What Does Pullout Test Mean?

A pullout test gauges the strength of a particular specimen through the use of dedicated tension jacks, which are injected into the specimen under testing.

This test is usually conducted in industrial settings to prevent malfunctions that may be brought on by loosened and weakened hardware due to a variety of factors, such as unstable temperatures. This test is typically conducted to set up hardware strength for airports, railways and other types of commercial and industrial structures.


Corrosionpedia Explains Pullout Test

The durability and strength of anchor bolts, safety wires, eyebolts and other hardware can be affected by various factors. Thus, it is essential that these components are checked and tested on a regular basis. Visual examination is not sufficient, so pullout testing should be performed as well.

This test works by attaching a small device to the hardware such as a screw, exterior bolt or nut. Then, this equipment is pulled, depending on the allocated level of stress, in order to gauge the strength and attachment of the hardware. Despite the fact that the bonding material may vary, the pullout test remains identical for all hardware types.

This test is highly beneficial in the early detection of possible issues. It helps in improving the design and anchor selection in industrial settings. Hence, safety can be promoted and the possibility of hardware failure can be mitigated at the earliest possible opportunity.
