ISO 16826:2025 is an international standard for non-destructive testing using ultrasonic methods to detect discontinuities perpendicular to the surface of metallic materials, specifically focusing on those with parallel or concentric surfaces. It provides guidelines for testing materials with thicknesses between 40 mm and 500 mm. The standard outlines principles for using techniques like the tandem technique and the longitudinal-longitudinal-transverse wave (LLT) technique to identify such defects.
