Product Samples We Regularly Subject to Glued Board Pallet Inspection

The coordinate‑measuring machines, the universal compression‑and‑bending test frames, the constant‑temperature and humidity chambers, the spectrophotometers, the gas‑chromatography–mass‑spectrometry systems and the mechanical‑shock and vibration tables in our facility accommodate a broad variety of glued‑board pallet designs and their constituent materials. The following categories represent the most frequently tested items:

Plywood‑deck pallets with solid‑timber or plywood blocks – the four‑way and the two‑way‑entry pallets that are assembled from the phenolic‑, the urea‑melamine‑ or the polyurethane‑bonded plywood panels and the glued‑or‑nailed blocks, used for the export and the domestic distribution of the packaged goods, the chemicals and the food products
OSB and the wafer‑board pallets – the pallets that are manufactured from the oriented‑strand‑board or the wafer‑board panels, often with the edge‑sealing or the moisture‑resistant coating, evaluated for the bending‑strength, the fastener‑holding and the resistance to the humidity and the rough handling
Moulded‑wood and the compressed‑wood‑fibre pallets – the one‑piece, the nestable pallets that are formed from the wood‑fibre and the thermosetting resin under the heat and the pressure, tested for the stacking‑strength, the impact‑resistance and the water‑absorption
LVL and the laminated‑veneer‑lumber stringer pallets – the heavy‑duty pallets that incorporate the high‑strength LVL stringers and the plywood or the LVL top‑decks, designed for the racking and the high‑load applications, evaluated for the bending‑stiffness and the long‑term creep behaviour
Composite‑block pallets with the glued wooden‑fibre or the recycled‑plastic blocks – the pallets that combine the plywood or the OSB deck‑boards with the composite‑material spacer‑blocks, assessed for the block‑shear, the vibration‑loosening and the resistance to the cleaning‑chemicals
Prototype, field‑returned and the accelerated‑ageing‑exposed glued board pallet specimens – the pallets that have been subjected to the multiple‑trip use, the exposure to the rain and the sun, the forklift‑impact or the in‑service failure, submitted for the residual‑strength, the glue‑line‑degradation and the root‑cause failure analysis
