UN Certified FIBC Bags are specially designed and constructed for transportation of dangerous materials. These are made in strict compliance with the United Nation’s recommendations for the transport of dangerous goods.
There are four types of FIBCs for dangerous goods:
13H1: woven PP without coating & without liner
13H2: woven PP, coated & without liner
13H3: woven PP, uncoated & with liner
13H4: woven PP, coated & with liner
Tests that are applied on the bags in order to verify UN requirements are as follows:
Tear test- 100mm tear is made on the side of the FIBC which is filled with the maximum load. The bag is then filled with twice its maximum load for five minutes. At the end, the FIBC is suspended with its SWL for another five minutes
Top lift test- Loaded with six times the maximum load
Stacking test- Bag with maximum load is further loaded with 1.8 times the permissible weight
Topple test- FIBC with the maximum load is toppled from a height of 80 cm or 120 cm depending on the material packed inside
Drop test- FIBC with the maximum load is dropped from a height of 80 cm or 120 cm in an upright position
Righting test- Post toppling, FIBC with the maximum load is lifted to an upright position on one or two loops
