Proof (Burst) Test Requirements for Canadian Registration (CRN)
Burst Testing
Pressure Vessel Engineering regularly completes and provides burst testing services. We can complete physical testing or simply provide assistance where needed. We have years of experience using burst testing to register products and have the knowledge to get the job done right and as economical as possible.
Benefits of using PVEng:
- 10+ years of successful experience
- Extensive knowledge of registration requirements
- Fast professional service
For projects of several components we can identify the minimum amount of testing required and provide more economical approaches when appropriate. We also provide Finite Element Analysis for components which are not appropriate for destructive testing.
We would be happy to discuss your project with you. For more information please contact:

Burst testing is a form of physical testing using a pressurized medium to load a component. This testing can be used to justify component designs that are too complex for analytical calculations. Guidelines for this type of testing can be found in ASME Section VIII Division 1 under design Section UG-101. Here formulas are used to determine a maximum allowable working pressure (MAWP) from the measured burst pressure. The MAWP can be used to justify the component for different applications or obtaining a Canadian Registration Number (CRN). An authorized inspector must witness the test and sign off on the results if the test is to be used for the purpose of proving an acceptable design pressure for CRN. In addition to the AI further documentation such as mill test reports (MTR) and material specifications are required to prove actual and minimum physical properties of the component material. The physical properties along with corrosion and efficiency factors directly affect the resulting MAWP calculation. For example, higher expected corrosion and weaker materials will both lower the calculated MAWP. The MAWP is not the only key piece of information yielded by burst testing. The results of a burst testing allow designers to observe actual failures in the design and will provide them with valuable insight for optimization.
