Determines extensibility of paint coatings on metal panels which are clamped in position and formed round the conical mandrel by rotation of the roller frame.
The 200mm mandrel tapers from 37mm to 3mm diameter. After test the panels are examined to determine minimum diameter at which failure by elongation occurs.
