GB19434.1:2004 established and the following terms and definitions apply This standard applies. 3.1
Metal IBC's, also known as metal intermediate bulk containers, refer to a packaging container that meets the definition of intermediate bulk containers in GB19434.1-2004 and consists of a metal box and appropriate auxiliary equipment and structural devices. Metal intermediate bulk containers are of two types: a) used for transporting solids that are loaded or unloaded by force (11A1IB, 11N); b) used for transporting solids that are loaded or unloaded at a gauge pressure greater than 10kPa (21A21B, 21N); c) used for transporting liquids (31A, 31R, 31N). Intermediate bulk containers intended for transporting liquids and meeting the requirements of this standard cannot be used to transport liquids with a vapor pressure greater than 110 kPa at 50°C or a vapor pressure greater than 130 kPa at 5.5°C. 4 Requirements
4. Metal intermediate bulk containers intended for liquids shall be subjected to a sealing test when first used and when put back into use after repair. In this case, the intermediate bulk container does not need to be equipped with its own closing device. 4.2 The box body shall be made of suitable ductile metal materials that have fully demonstrated their weldability, and the welding process shall be good and absolutely safe. If necessary, low temperature performance shall be considered. 4.3 If the contact between the material used to manufacture the box body and the material used to manufacture the box body will cause the box wall thickness to decrease continuously, the box wall thickness shall be increased during manufacturing. This allowable corrosion thickness shall be added to the box thickness determined in accordance with 4, 7 of this standard. 4.4 Care shall be taken to avoid damage caused by the stray effect caused by the juxtaposition of different metals. 4.5 Lead intermediate bulk containers used for the transportation of flammable liquids shall not have moving parts made of unprotected steel that is prone to rust. 4.6 The metal used to manufacture metal intermediate bulk containers shall comply with the provisions of SN/T0987.8, Section 4.6. 4.7 The minimum wall thickness of metal intermediate bulk containers shall comply with the provisions of 4.7 of SN/T0987.8. 4.8 Functional bulk containers loaded with liquids shall be able to discharge a sufficient amount of vapor when the container is engulfed by flames to ensure that the container will not crack. This can be achieved through conventional pressure relief devices or other structural devices. 4.9 The initial degassing pressure should not be higher than 65kPa; nor lower than the total gauge pressure of the intermediate bulk container at 55℃ (that is, the partial pressure of the vapor pressure of the content, air or other inert gas, less than 100kPa). The required decompression device should be installed in the vapor space. 4.10 The performance test requirements of metal intermediate bulk containers are shown in Table 1. 1 Performance test requirements
