How are FIBC bags tested before use?
The contents that UN bags carry can sometimes be too dangerous or volatile in nature. Hence, an extreme testing procedure is a mandate before it can be actually put to use. A one-hour vibration test followed by side or top lift for next five minutes is what the testing procedure begins with. Then next procedure is a stacking test to check whether it loses contents or not followed by a drop test taken from a number of different heights. A topple test is then conducted on any part of the top without the loss of contents. With FIBC on its side the bag is lifted into the upright position to check if there is any kind of damage done to the bag. The ultimate test is the knife test where it is checked that the bag should not increase more than 25 percent of its original length.
