GB/T 21587-2008 specifies the method of dropping test for dangerous goods intermediate bulk containers. It specifies the parameters of the falling equipment required for the test to ensure that the equipment can accurately simulate the possible falling scenarios in actual transportation. The preparation of samples for intermediate bulk containers is described in detail, including filling simulated dangerous goods and sealing methods. During the test, the operation is carried out in strict accordance with the specified drop height, angle and drop location. By observing whether the container is damaged after the test, whether the contents leak or not, the protective performance of the container against dangerous goods under drop conditions is evaluated. This standard provides a key basis for ensuring the safety of dangerous goods transportation and standardizing mass testing of intermediate bulk containers.
