Dropping a 1/4 scale model package from 30 feet onto an unyielding target. (the unyielding target forces all of the deformation to be in the package, none in the target).	Drop test of 1/4 scale model impact limiters from 30 feet onto an unyielding target.	Dropping a 1/3 scale model package from 40 inches onto a rigidly attached (welded) 2 inch diameter steel spike.	Dropping a 1/2 scale model package from 40 inches onto a rigidly attached (welded) 3 inch diameter steel spike.	1/8 scale model simulation of a highway/railroad crossing accident. The results of this test match the results of the full-scale test of this highway/railroad crossing accident.

*** Because leakage past seals does not scale, packages that are certified using scale model tests enforce no-deformation in the closure region to guarantee there is no leakage.
