This paper presents a new nondestructive technique using a non-contact ultrasound scanner, suitable for the testing of fibre cement boards. The capabilities of this technique for locating defects in usually unilaterally accessible fibre cement boards during their production are described. An original test methodology developed for this purpose is included. The methodology was verified through laboratory tests on specimens and through trials on a production line. The suitability of this technique for testing fibre cement boards and its reliability have been confirmed.
