About the AAR testAbout the AAR test: AAR test is a rigorous test. Rail transport is one of North America’s primary logistics tools, one in which drastic sloshing of liquids occurs where rail tracks intersect, or when train carriages go uphill/ downhill, or are coupled - along with huge impacts on the panels of containers, both inside and outside. Therefore, for a plastic collapsible and large-volume IBC, the AAR test is a direct and authoritative testimony of its reliability. IBC OF330 has been designed to pass the AAR test from the very beginning. And after more than 4 years, it officially passed the AAR test (No. 811) on April 29, 2019.
