A method of inspecting the fragmentation pattern of a single ply of toughened glass, following a fragmentation test carried out in accordance with ECE R43 involves illuminating a first portion of the ply of glass in transmission using a strip light source located on a first side of the transparent support. An image of the first portion of the ply of glass is captured using an image capture device located on a second side of the transparent support means, aligned with and fixed in a relative position to the strip light source. A series of images of the glass are collected and analyzed to produce an image of the fragmentation pattern. Imaging can be performed using an apparatus for carrying out the imaging.
