Drum Components Of UN Packagings Are Not Interchangeable

The entire design of a UN drum, and all its components (metal thickness, heads, ring, gasket, bolt, nut, plugs), is defined at a performance test. These elements comprise a drum type, or certification, that must meet a specific test standard for classified haz-mat products. Packaging users cannot alter or change any of these components, as it will impact the ability for the drum to perform as certified. If replacement parts are needed, fillers must make sure that they get the originally tested components from the manufacturer. Once a drum enters transportation, compliance with the UN certification is the responsibility of the shipper.
