-YKAONKAca-
4.4 The seams of flexible intermediate sensitive containers shall be sewn, pressed, bonded or other methods. All sewn seam ends shall be reinforced.
4.5 Flexible intermediate bulk containers shall be sufficiently resistant to aging and degradation caused by ultraviolet radiation, weather or the substances contained, which may affect their use.
4.6 If ultraviolet protection is required for flexible intermediate bulk containers, carbon black, pigments or inhibitors may be added. These additives shall be compatible with the contents and remain effective throughout the service life of the container body. If the carbon black, pigments or inhibitors used are different from the additives used in the manufacturing design type test, retesting may be exempted as long as the content of carbon black, pigments or inhibitors does not have a negative impact on the physical properties of the construction materials. 4.7 In addition to the use of additives for ultraviolet protection, the plastic material composition may also include some additives for other purposes, but these additives shall not have a negative impact on the physical and chemical properties of the material. 4.8 Recycled old container materials shall not be used to manufacture the box of flexible intermediate bulk containers, but residual materials or scrap materials from the same production process may be used. The above requirements do not exclude the reuse of parts such as joints and pallet bases, but it must be ensured that these parts are not damaged in previous use.
4.9 After the flexible intermediate bulk container is filled, the ratio of width to width should not be greater than 2:1. 4.10 The lining should be made of suitable materials. The strength of the materials used and the structure of the lining should be compatible with the capacity and purpose of the flexible intermediate bulk container. The interface and closing device should be leak-proof and able to withstand the pressure and impact that may occur under normal transportation and loading and unloading conditions. 4.11 The performance test requirements for flexible intermediate bulk containers are shown in Table 1.

5 Tests
5.1 Test items
The intermediate bulk container or its lifting device shall not have any damage that may affect the safety of transportation. The expansion of the cut shall not exceed 25% of its original length, and there shall be no loss of contents. The container body shall not be deformed in a way that may endanger the safety of transportation. There shall be no loss of contents. A small amount of contents may leak out from the seal or joint after falling. However, when the intermediate bulk container is lifted to the ground, no further leakage occurs. It shall be judged as closed and the contents are not lost. After the impact, a small amount of the contents are exposed from the seal or seam, or it is not completely filled, it should be judged as unqualified. The intermediate bulk container and its lifting device shall not have any damage that may endanger its transportation and safety. The test items of flexible intermediate bulk containers are shown in Table 2. 5.2 Number of samples
5.2.1 The number of samples for different test items is shown in Table 2. Table 2 Test items and sampling quantity

GB 19434.4—2004
5.2.2 Without affecting the test results, it is allowed to reduce the sampling quantity and conduct multiple tests on one sample at the same time. 5.3 Test preparation
Medium sensitive containers made of paper shall be preconditioned for at least 24 h under a high pressure, controlled temperature and relative humidity. There are three options, one of which can be selected. It is recommended to choose 23℃±2℃ and 50%±2%. The other two options are 20℃+2℃ and 65%+2% or 27+2℃ and 65%±2%.
Note: The average value should not exceed these limits. Short-term fluctuations and measurement limitations will cause changes in each measurement. The relative humidity can vary by ±5%, which will not seriously damage the test repeatability.
