Side-Drilled Hole
A small hole (typically 1-3mm diameter) drilled horizontally into a calibration block from the side, perpendicular to the scanning surface. Side-drilled holes are used in IIW and other reference standards to simulate point-source reflectors for ultrasonic equipment calibration and evaluation. They simulate small internal flaws and are excellent for establishing sensitivity and resolution. Proper positioning of side-drilled holes at different depths ensures full-thickness coverage verification.

Equipment Selection and Use
Proper selection and maintenance of side-drilled hole is critical for successful NDT inspections. Equipment must be calibrated and verified per applicable standards.
Maintenance and Verification
Regular maintenance and calibration verification ensure reliable equipment performance. Equipment that falls out of calibration can produce unreliable results.
Best Practices
- Always follow applicable NDT standards and procedures
- Use properly calibrated and maintained equipment
- Ensure personnel are properly trained and certified
- Document inspection procedures and results completely
- Keep current with industry standards and best practices
