An acceleration test is designed to quantify the rigidity of palletized goods subject to horizontal inertial forces.
[1] The test was invented by Marc Juwet of KU Leuven[2] in 2008 and is now in worldwide use.
During the test, the sides of the pallet load are not supported, thus allowing the products and the packaging to deform.
Pallet loads that resist an acceleration test up to 0.5 g, can be prevented from sliding and tilting in the transverse transport direction.
Most often a single lashing, support by a vehicle wall or other pallet loads provides a legally required safety level in most countries.
