Burst attempt

The bursting test is a component-oriented, destructive test to determine the bursting pressure of hollow bodies . The maximum tensile stresses that can be tolerated in a material can be determined from the bursting pressure using the boiler formula . Since it is more complex and less reliable in design and recording than the classic tensile test , it is used less often and is only standardized for certain applications .

attempt

The hollow component is sealed except for an inlet opening and slowly (quasi-statically) filled with a fluid until it bursts. The maximum pressure that occurs is the burst pressure. Liquids, in particular water, are preferred as the fluid , since they do not expand or expand only weakly when they burst. The attempt then often only ends with a leak . In contrast, when using gaseous fluids, increased safety measures are required in order to recapture debris from the exploding sample.

application

The burst test is used for smaller pressure vessels such as PET bottles for beverages, gas bottles for technical gases , compressed air bottles , etc. It can also be used to test pipes and hoses . Since this is a destructive process, this is only possible on a random basis for quality assurance purposes.

It is also used for technical ceramics . B. used for hip prostheses , as they can withstand high tensile stresses and are also tensile until they break.
