This part of ISO 12777 describes test methods for the determination of the bending resistance of pallet nails, staples and other dowel-type fasteners. It includes tests for the a) ultimate strength in static bending (three- and four-point loading methods); b) impact bend resistance (three-point loading method). These test methods apply to all types of nails, including loose, collated or coil nails, up to 6 mm in diameter (round, square, fluted, twisted, plain or threaded) and may also be suitable for other fasteners such as staples.
