Abstract
Overview - ISO 19397:2024 (Ultrasonic film thickness measurement)
ISO 19397:2024 specifies a non-destructive method for determining the on metallic and non‑metallic substrates using an . This first edition replaces and provides updated normative references and an added introduction. The method is based on time‑of‑flight measurement of ultrasonic echoes (A‑scan) from coating interfaces and converts sound travel time to dry film thickness when the sound velocity in each layer is known.
