Why leak test? Leak testing is performed to ensure that when in service, the component or assembly has zero leakage or a leakage that is acceptable over time for the fluid/gas that it is meant to contain, or conversely to prevent material on the outside from leaking in.
When it comes to testing aerospace components, the costs of imperfections go far beyond the financial. Thus it is critical that nondestructive testing (NDT) for aerospace vehicles and parts is made foolproof in finding even the tiniest hint of damage or defect.
Aircraft are the backbone of several industries and, as such, are subjected to intense and near-continuous use, making preventive maintenance critical. Maintenance protocols are exhaustive, but time-consuming, especially when fuselage and wing longerons are involved.
Established in 1993, DICONDE (Digital Imaging and Communication for Non-Destructive Evaluation) is an imaging and archiving technology standard that defines all image attributes and elements in a universal format. DICONDE was based on DICOM (Digital Imaging and Communications in Medicine), a proven imaging and archiving standard in the medical industry. In 2004, the American Society for Testing and Materials (ASTM) E07.11 subcommittee made DICONDE the standard (E2339-11) for NDT (nondestructive testing) imaging.
