Almost all liquid goods with a density up to 2.4 are now packed securely including dyes, acids, varnishes, foodstuff, or other special solutions. An IBC that is approved to store and transport liquids with this density is unique on the European market, Werit claims.
To guarantee the performance of the IBC in transporting material of extreme density, Werit conducts a stress test in which the container is filled and stored holding the original content for six months. This exposes the packaging to any potential damaging impact from the liquid. After this period of conditioning, the IBC is cleaned of all the residues from the original charge, then filled with water and antifreeze. Within 48 hours, the mixture is cooled down to -20 degC and then dropped from a height of 2.4m. The conventional IBC would only have to withstand a drop from a maximum height of 1.9m.
Following this process further tests are conducted for leaks, vibration, lifting, and stacking, and a hydraulic internal pressure test with 100 kPa.
