    Scope and Requirements
    • EN 10228-3 describes ultrasonic testing of ferritic and martensitic steel forgings
    • Test applies to four types of forgings classified by shape and production method
    • Testing must be performed after final quality heat treatment
    • Manual pulse-echo technique with scanning speed not exceeding 150 mm/s
    Equipment and Surface Conditions
    • Normal probes with frequencies 1-6 MHz and effective crystal diameters 10-40 mm
    • Shear wave probes with beam angles 358-708 and effective crystal areas 20-625 mm2
    • Scanning surfaces must be free from paint, scale, and irregularities
    • Surface finish must match required quality class
    Scanning and Classification
    • Grid scanning or 100% coverage required based on forging type
    • Two types of indications: Pattern 1 for small discontinuities, Pattern 2 for large
    • Discontinuities classified as point, extended, isolated, or grouped
    • Recording levels and acceptance criteria specified for different quality classes
    Quality Control
    • Personnel must be qualified according to EN 473
    • Equipment must be calibrated and checked according to prEN 12668-3
    • Reference blocks required for sensitivity and defect sizing
    • Couplant must be removed after testing if not affecting subsequent operations
