HB 5460-1990 (English Version) PDF

Scope: This standard specifies the method principles and classification, environmental conditions, equipment and instruments, couplant and comparison test blocks, testing steps, evaluation, acceptance, technical documents and requirements for testing personnel for the ultrasonic penetration C-scan imaging method to detect honeycomb components. . This standard is suitable for testing the bonding quality of metal honeycomb components, such as detecting defects such as delamination, holes, and debonding. It is also suitable for testing the bonding quality of metal or fiber reinforced composite skins - Nomex honeycomb components and laminate components. However, this standard does not apply to components without symmetry planes and complex shapes.
