Drop height
Packing group III
SN/T0987.6—2013
Unit: meter
No loss of contents. After the drop, a small amount of contents leaked out from the seal or seam. However, when the flexible intermediate bulk container is lifted off the ground, no further leakage occurs and it should be judged as qualified. 6.3.5 Overturning test
Scope of application
Applicable to various flexible intermediate bulk containers.
Sample preparation
The flexible intermediate bulk container to be tested should be loaded to not less than 95% of its capacity and its maximum allowable load, and should be evenly distributed. 6.3.5.3 Test method
Tip the flexible intermediate bulk container over so that any part of its top hits a hard, inelastic, smooth, flat and horizontal surface.
The tipping height is shown in Table 3.

Packing class Positive
Qualification criteria
Packing class III
Unit: meter
No loss of contents. After the impact, a small amount of contents leaks out from the seal or seam. As long as there is no continuous leakage, it shall be judged as qualified. 6.3.6
Recovery test
Scope of application
Applicable to various flexible intermediate bulk containers lifted from the top or side. 6.3.6.2
Specimen preparation
The flexible intermediate bulk container to be tested shall be loaded to not less than 95% of its capacity and the maximum allowable load, and shall be evenly distributed. 6.3.6.3
Test method
The flexible intermediate bulk container is laid flat on the ground with its side facing downwards. It is lifted to an upright position and off the ground at a speed of 0.1 m/s using one or two lifting devices (if there are four lifting devices). 5

6.3.6.4 Qualification criteria
The flexible intermediate bulk container and its lifting device shall not have any damage that may endanger the safety of transportation and handling. 6.3.7
Qualification criteria
If all the above tests are qualified, the inspection batch is judged to be qualified. Disposal of unqualified
If only one of the inspection results is unqualified, double sampling should be carried out for re-inspection. If there is still one or more unqualified items, the inspection batch is judged to be unqualified.
