Chapter 4, Chapter 5 and Chapter 6 of this standard are regulatory and the rest are recommended. CI 19434.8-204 This standard is equivalent to the United Nations Standards for the Transport of Hazardous Chemicals (3rd revision), 2003. This standard was issued by the National Technical Committee for the Administration of Hazardous Chemicals StandardizationThe definition of medium-sized packaging container in 4 is that the container body is a medium-sized modified container with attached plasticizer, which only has structural devices and corresponding capture aids.

f)3_H? For the rigid small-sized containers, the containers should be made of standard plastic materials and strong enough to be suitable for their intended use. The materials used in the manufacturing process should be protected from deterioration by ultraviolet radiation. The low-temperature performance of the materials should be taken into consideration: under normal transportation conditions, the quality of the goods should not be degraded. 4.2 If ultraviolet protection is required, paint or other suitable materials or preparation methods should be used. These additives must be compatible with the contents and effective over the life of the container. For example, the carbon, pigment and other additives used should not be the same as those used in the manufacturing design. The materials or preparations will not have adverse effects on the general properties of the manufacturing materials. The new test can be exempted.
4.3 In addition to the use of ultraviolet protection additives, the plastic material can also contain some other additives, but these additives shall not have a negative impact on the physical and chemical properties of the material. 4.4 Except for the residual materials and waste materials produced by the same production process, recycled materials shall not be used to manufacture medium-sized containers made of steel.
4.5 For medium-sized containers made of transport vehicles, the pressure inside the container shall exceed the pressure of the container, and the hot air shall be discharged through the medium-sized container. Conventional decompression methods can be used, or other equivalent methods can be used. bZxz.net
4.6: Medium-sized containers made of decomposable plastics should be subjected to attenuation tests after each use and after final disposal. Medium-sized containers do not need to be equipped with their own protective devices. 4.7 Medium-sized containers made of decomposable plastics The performance test requirements of the micro-capacity container are shown in Table 1.

There is no loss of internal materials, no permanent deformation of the medium-sized container including the box tray that may endanger the safety of the container. ||No filter, no suitable for the industry and the model of the collection of the inspection of the world's transportation and the permanent deformation of the gold. The contents are not damaged. After the contents are full, if there are more than one stop from the plan, there is no need to make any progress. Before the step is learned, it should also be a platform. The standard test items of plastic medium bulk containers are shown in the table? Table 2 Test items

5.3.6.1 Use a single-material type flexible device with a free pressure. 5.3.6.2 Sample specifications: According to the design type of the device, for devices carrying solids, the volume must be not less than 9. For devices carrying liquids, the volume must be not less than dry. The reduction device should be determined to be in a state where it will not be closed or removed. The test of the container should be carried out when the pressure of the test sample and its contents drops to -18T or below. The test liquid should be kept in a concentrated state. If necessary, a refrigerant should be added. If the test material can have sufficient ductility and tensile strength at a lower temperature, this temperature treatment condition can be ignored. Test method of 5.3.6.3: Follow 6, 2.5.4 of SN/T098V4. 5.3.6.4 is generally 2. See Table 4. Table of drop height [Level test] Straight collar packaging Hillside packaging Color level meter 5.3.G.5 When the drop test is carried out on a medium-sized plastic container to be loaded with a reduced volume, if another material is used, the relative density and viscosity of the material should be the same as that of the material to be transported. Water can also be used for the drop test. The drop height is as follows:) The relative density of the material to be transported exceeds 1.2. The drop height is shown in Table 4: The relative density of the material to be transported is greater than 1.2. The drop height of the container should be calculated based on the relative density of the material to be transported (the first smaller one is taken from the fourth and fifth parts). See Table 5. Calculation of drop height [maximum] 6 Inspection plan and generally 6 meters per unit area. Manufacturing! The company guarantees that the rigid bulk containers it produces meet the requirements of this standard and conducts technical inspections with relevant inspection departments: The company has the following requirements: 6.2 Inspection items: The company conducts inspections on the products it receives in accordance with the requirements of this standard: 6.3 Rigid bulk containers: The company allows one of the following precautions: When new products are put into production or when production capacity is changed: After production, if there are significant differences in structure, material, and process that may affect product performance, such as external dimensions, etc., if there are slight differences between the medium-sized container and its similar design, such as external dimensions, etc., the company can allow this type of bulk container to be used for sample testing:
Normal production: Once every six months
When the product is in normal production, the factory inspection results are significantly different from the primary and secondary inspection results:
The national quality supervision agency also allows the company to conduct performance inspections. 6.4 The inspection shall be carried out according to the requirements of environmental protection. If one sample of an item fails to meet the requirements, the item shall be deemed qualified.
