What Is Proof Testing?

A proof test is a type of stress test that is used to ensure that a load-bearing structure is capable of withstanding expected loads. Proof testing is usually done before new structures are initially used and periodically afterward to ensure the unit still functions correctly.

Proof Testing Applications

Proof testing is performed in a variety of industrial situations. Industrial equipment, such as cranes and derricks, are usually tested to ensure they can safely handle heavy loads. Because turbomachinery is operated at high speeds, proof testing is done to ensure the machinery is capable of being operated at expected speeds and that the overspeed safety mechanisms function correctly. Because pressure vessels must be able to handle high-pressure applications without failing, industrial pressure testing Houston TX companies perform proof testing as part of safety protocols. Because the barrel temporarily becomes a pressure vessel when fired, firearms also undergo proof testing.

Reasons for Proof Testing

Proof testing is primarily done to ensure that products, structures and equipment are fit for their intended use. It is also a critical component of safety testing. Failures can lead to severe injuries or property damage, so it is important to ensure that units can withstand expected stresses and that safety mechanisms function correctly when those stress levels are exceeded. Additionally, international safety standards may require proof-testing to be performed to remain compliant.

Occupational Safety and Health Administration Safety Standards

In addition to international safety standards, OSHA requires proof testing of some industrial equipment. OSHA guidelines require employers to maintain a safe workplace. Part of this requirement is ensuring that any equipment used by employees can be safely used for the intended purpose. Proof testing is essential for ensuring that workers are not injured by equipment failures.

Proof testing is an essential component of safety protocols for many types of industrial equipment. Proof testing helps keep workers safe and protects valuable property and equipment.
