There are four types of FIBC for dangerous goods made from woven polypropylene:
13H1: woven PP without coating and without liner
13H2: woven PP, coated and without liner
13H3: woven PP, uncoated and with liner
13H4: woven PP, coated and with liner

Top lift test: The FIBC is loaded with six times of the rated load.
Drop test: The FIBC filled with the rated load is dropped in an upright position from a height of 80 cm or 120 cm.
Topple test: The FIBC filled with the rated load is toppled from a height of 80 cm or 120 cm.
Righting test: After being toppled, the FIBC filled with the maximum load is lifted to an upright position on one or two loops.
Tear test: A 100 mm tear is made on one of the sides of the FIBC filled with the maximum load. The FIBC is then filled with twice its maximum load for a minimum of five minutes. Finally, the FIBC is suspended with its SWL for five minutes.
