Dangerous goods packagings are subject to strict international recommendations published by the United Nations. Such standards (UN) recommend that packagings undergo a series of extremely rigorous tests. Solvent-based paints are classified under dangerous goods and paint manufactures must use onerous reinforcement systems in secondary packagings such as plastic locks and corrugated cardboard boxes to meet these standards.
Among the exacting tests conducted for approval, the most difficult tests are:
After extensive work with lid and ring profiles and densities, in December 2000, Brasilata successfully produced the quarter and the 1/16 gallon cans which passed the rigorous tests conducted by the Departament of the Navy one of the Brazilian certifying agencies. Later on in January 2002, our R&D and Prototype departament developed the 1 gallon can that resisted the same test as well. Important to stand out the 1/16 gallon can during the tests resisted 250 Kpa of internal pressure becoming possible its use for the highly dangerous products transportation.
According to specialists, no other pressure lid can had been found in world records able to withstand such tests without the aid of auxiliary seals.
Several sources have reported that companies in some countries have sought to decrease the test levels so that a conventional can might be aproved for transportation of dangerous goods.
This is not necessary anymore.
