4.1 General requirements
4.1.1 Rigid IBCs shall not deform under the influence of the external environment. 4.1.2 Under normal conditions of transport, including the influence of vibration or changes in temperature, humidity or pressure, the construction and closure of IBCs shall ensure that their contents will not leak.
4.1.3 IBCs and their closure materials shall be compatible with the substances contained or have the ability to protect the contents from: a) contact with the contents, making the IBC dangerous to use; b) react or decompose with the contents, or react with the materials of which the IBC is made to form toxic or hazardous compounds.
If cushioning material is used, the cushioning material shall not be damaged by the contents of the IBC. 4.1.4
4.1.5 All auxiliary equipment should be reasonably located and properly protected to prevent damage during loading, unloading and transportation that may cause leakage of the contents. 4.1.6 Intermediate bulk containers and their ancillary equipment, auxiliary equipment and structural equipment should be designed to withstand the pressure of the materials contained and the stress of normal loading, unloading and transportation, and the contents will not be lost. Intermediate bulk containers that need to be stacked should comply with the stacking design requirements. The lifting and fastening devices of intermediate bulk containers should be of sufficient strength to withstand normal loading, unloading and transportation conditions without overall deformation or breakage. These devices should be properly located and should not cause excessive stress to any part of the intermediate bulk container. 4.1.7 If the intermediate bulk container consists of a box body in a frame, the following structural requirements shall be met: a) There shall be no collision or friction between the frame and the box body that may cause damage to the box body; 2
b) The box body shall be in the frame from beginning to end: SN/T0987.1—2013
If the connection between the box body and the frame is allowed to expand or move relative to each other, the various equipment of the intermediate bulk container shall be fixed in a suitable position so that the various equipment will not be damaged by such relative movement. 4.1.8 The bottom discharge valve of the intermediate bulk container shall be closed and tightened. The entire discharge device shall be properly protected to avoid damage. Valves using lever closing devices shall be able to prevent any accidental opening. The open and closed positions shall be obvious and easy to identify. Intermediate bulk containers for liquid cargoes shall also be equipped with auxiliary devices that can close the discharge port.
4.1.9 Before loading and delivery for transportation, the intermediate bulk container should be carefully inspected to ensure that it is free of any corrosion, contamination or other damage, and that all ancillary equipment functions normally. If there is any sign that the strength of the intermediate bulk container is lower than the test strength of its design type, the intermediate bulk container should be stopped from use or reprocessed to enable it to withstand the test strength of that type. 4.1.10 When the intermediate bulk container is loaded with liquid, sufficient space should be left above the liquid surface to ensure that the filling degree of the intermediate bulk container does not exceed 98% of its total capacity when the average temperature of the cargo is 50℃. The maximum filling degree at different temperatures can be calculated according to formula (1): Filling degree
Where:
1+g(50-)
-The average coefficient of volume expansion of the liquid substance at a temperature of 15℃~50℃ t-The average temperature of the liquid during filling. For a maximum temperature rise of 35°C, α can be calculated according to formula (2): dis-dso
35xdso
where:
d15——relative density of liquid at 15°C; dso—relative density of liquid at 50°C
4.1.11 When two or more closing devices are used in series, the closing device closest to the transported material should be closed first. 4.1.12 During transportation, no hazardous residues shall adhere to the outside of the intermediate bulk container. 4.1.13 Uncleaned aerial bulk containers that have been used to transport hazardous substances shall also comply with the requirements of this standard unless adequate measures have been taken to eliminate their hazards.
4.1.14 When intermediate bulk containers are used to hold liquids with a flash point equal to or lower than 60°C, or to transport powders that are prone to dust explosion, anti-static measures should be taken.
4.1.15 When the solid substance to be transported may liquefy at the temperature during transportation, the intermediate bulk container shall also meet the relevant requirements for containing liquid substances.
4.2 Special requirements
4.2.1 Special requirements for the transportation of organic peroxides in intermediate bulk containers. Each organic peroxide shall be tested and accompanied by a report to prove that it is safe to transport the substance in an intermediate bulk container. The test shall include: a) Proof that the organic peroxide complies with the relevant classification principles of the International Dangerous Goods Code; b) Proof of the compatibility of the materials in contact with the substance during transportation and the substance: If necessary, determine and control the emergency temperature based on the self-accelerated decomposition temperature (SADT). These temperatures may be lower than the package temperature specified in the International Dangerous Goods Code; d) If necessary, design an emergency decompression device and formulate special requirements necessary to ensure the safe transportation of organic peroxides. 4.2.2 Special requirements for the transport of self-reactive substances in 4.1 in IBCs 4.2.2.1 Self-reactive substances in 4.1 shall be tested and accompanied by a report indicating that they are safe for transport in IBCs. Contingencies that need to be considered include the fact that the substance can be easily ignited by external ignition sources such as sparks and flames, and that excessive transport temperatures or contamination may easily lead to strong exothermic reactions. 4.2.2.3 In order to prevent the explosion of metal IBCs or composite IBCs with complete metal shells, the emergency pressure relief device shall be designed to release all decomposition products and vapors within a time not exceeding 1 hour in the event of fire (heat load 110kW/m2) or during self-accelerated decomposition. 4.2.2.4 Self-reactive substances with a self-accelerated decomposition temperature below 55°C when transported in IBCs shall be handled in accordance with the temperature control requirements of the International Dangerous Goods Code.
