The burst test is a destructive test and is applied to detect the high pressure capacity of pressure containing parts. The tests are usually done with a liquid. This test is mainly performed as a pre-production test to meet safety and quality standards. To verify the reliability of products, it is important to determine the margin between the highest working pressure and the pressure when the product fails completely. Particularly for products where failure is not an option, burst testing is performed at the pre-production stage and testing is often done periodically on non-production parts.
Briefly, the objectives of the burst test are:
A product typically has several pressure ratings, and these need to be verified in the development or production environment. Proof pressure is the highest pressure that can be applied to a product without causing permanent damage to its working function. Burst pressure, on the other hand, is the upper pressure limit that can be applied without causing catastrophic failure in the component. It is expressed as multiples of the maximum pressure or upper pressure range value. In hydraulic equipment, this value can be as high as ten times the maximum working pressure. Burst pressure testing continues to increase the pressure beyond the proof pressure until the component fails. These test pressures can easily reach 20 or 60 PSI.
Briefly, the burst test is a test method used to determine the highest pressure at which a given component will explode when pressure is applied under controlled conditions. This test is invaluable for assisting design engineers in material selection, wall thickness, or component geometry such as cross holes, strain risers, and similar components. Knowing the maximum burst pressure is a vital consideration for any component under pressure, helping to establish safety design margins. Determining the maximum burst pressure of a component gives manufacturers and consumers confidence.
