Performance test requirements
No loss of contents, and no permanent deformation of large packages that endangers transportation safety. No loss of contents, and no permanent deformation of large packages that endangers transportation safety. No loss of contents, and no permanent deformation of large packages that endangers transportation safety. No loss of contents, and no permanent deformation of large packages that endangers transportation safety; if a small amount of contents leaks out of the seal after falling, it should be judged as qualified as long as there is no further leakage; large packages containing Class 1 explosives shall not have any leakage. 5.2.1 See Table 2 for the number of samples for different test items.

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
5.3.1 The large packaging prepared for transportation, including the inner packaging and articles used, should be tested. The liquid in the inner packaging should not be less than 98% of its maximum capacity, and the solid in the inner packaging should not be less than 95% of its maximum capacity. If the inner packaging of the large packaging will be used to transport liquids and solids, the liquid or solid contents shall be tested separately. The substances or articles in the inner packaging to be transported in large packaging can be replaced by other substances or articles, but doing so shall not invalidate the test results. When other inner packagings or articles are used, they shall have the same physical properties as the inner packagings or articles being transported. Additives, such as lead shot bags, are permitted to achieve the required total mass of the package, but this shall not affect the test results.
5.3.2 For large plastic packagings and large packagings containing plastic inner packagings (except plastic bags for solids or articles), the temperature of the test samples and their contents shall be reduced to -18°C or lower during the drop test. If the materials concerned have sufficient toughness and tensile strength at low temperatures, this pretreatment may not be considered. Test samples prepared in this way may be exempted from the pretreatment in 5.3.3. The test liquid shall remain in liquid form and antifreeze may be added if necessary. 5.3.3 Large fiberboard packagings shall be placed in an environment with controlled temperature and relative humidity for at least 24 hours. There are three options below, and you can choose one of them: The best environment is a temperature of 23°C ± 2°C and a relative humidity of 50% ± 2%. The other two options are: temperature 20℃±2℃ and relative humidity 65%±2%; or temperature 27℃±2℃ and relative humidity 65%±2%. Note: The average value should be within these limits. Short-term fluctuations and measurement limits may cause individual relative humidity measurements to vary by ±5%, but will not have a significant impact on the repeatability of the test results.
5.4 Test content
5.4.1 Bottom lifting test
5.4.1.1 Scope of application: Large packaging equipped with bottom lifting device. 5.4.1.2 Sample preparation: The large packaging should be loaded to 1.25 times its maximum permissible total mass, and the load should be evenly distributed. 5.4.1.3 Test method: The large packaging is lifted and lowered twice by a crane, with the fork bucket positioned in the middle and the interval being three-quarters of the length of the entry side (except for fixed entry points), and the fork bucket should be inserted into three-quarters of the entry direction. The test should be repeated from each possible entry direction. 5.4.2 Top lifting test
5.4.2.1 Scope of application: Large packaging equipped with a top lifting device. 5.4.2.2 Sample preparation: The large packaging should be loaded to twice its maximum permissible total mass. Flexible large packaging should be loaded to 6 times its maximum permissible total mass, with the load evenly distributed.
5.4.2.3 Test method: Lift the large packaging off the ground in the designed lifting method and keep it in the air for 5 minutes. 5.4.3 Stacking test
5.4.3.1 Scope of application: Large packaging used for stacking and storage. 5.4.3.2 Sample preparation: The large packaging should be filled to its maximum permissible total mass. 5.4.3.3 Test method: Place the bottom of the large packaging on a horizontal hard ground, and then apply an evenly distributed superimposed test load for at least 5 minutes. For large packaging made of wood, fiberboard and plastic materials, the duration is 24 hours. 5.4.3.4 Calculation of test load: The test load applied to the large packaging shall be equivalent to 1.8 times the sum of the maximum permissible total mass of the number of identical large packagings stacked on it during transport.
5.4.4 Drop test
5.4.4.1 Scope of application: Applicable to all large packaging. 5.4.4.2 Sample preparation:
a) According to the design type, large packaging used for transporting solids shall be filled to not less than 95% of its capacity, and intermediate bulk containers used for transporting liquids shall be filled to not less than 98% of its capacity. The pressure relief device shall be determined to be in an inoperative state, or the pressure relief device shall be removed and its opening blocked.
b) Large packaging shall be loaded in accordance with the provisions of this standard. The intended cargo may be replaced by other substances, but it shall not affect the test results. If it is a solid substance, when another substance is used instead, the physical properties (mass, particle size, etc.) of the substitute substance should be the same as those of the substance to be transported. It is allowed to use additives such as lead shot bags to achieve the specified total mass of the package, as long as the placement of the additives does not affect the test results. 5.4.4.3 Test method: The large package shall be dropped on a hard, inelastic, smooth, flat and horizontal surface, ensuring that the impact point falls on the most vulnerable part of the bottom of the large package. 5.4.4.4 Drop height: See Table 3

5.4.4.5 When the large package intended to contain liquid is dropped for test, if another substance is used instead, the relative density and viscosity of this substance should be similar to those of the substance to be transported. Water can also be used for drop test, and the drop height is as follows: a) If the relative density of the substance to be transported does not exceed 1.2, the drop height is shown in Table 3; b) If the relative density of the substance to be transported is greater than 1.2, the drop height should be calculated based on the relative density α of the substance to be transported (rounded to the first decimal place). See Table 4.

6.1 The manufacturer shall ensure that the large packaging produced complies with the provisions of this standard and shall be inspected by the relevant inspection department in accordance with this standard. The user has the right to request acceptance inspection for the received products in accordance with the provisions of this standard. 6.2 Inspection items: Inspect item by item in accordance with the requirements of Chapter 4 and Chapter 5 of this standard. 6.3 Performance testing should be conducted for large packages when any of the following conditions occur: - when new products are put into production or when old products are switched to new products; - after formal production, if there are major changes in structure, materials, and processes that may affect product performance. If there are only minor differences between large packages and their design types, such as a slight reduction in external dimensions, etc., selective testing may be allowed for such large packages; - once every six months during normal production; - when production is resumed after a long period of suspension; - when there is a significant difference between the factory inspection results and the last performance inspection results; - the national quality supervision agency proposes a performance inspection. 6.4 Judgment rules: Inspect each item item by item according to the requirements of the standard. If one sample fails in each item, the item is judged to be unqualified. If one item fails, the batch of products is assessed to be unqualified.
6.5 Unqualified batch processing: After the large packages in the unqualified batch are eliminated, they are submitted for inspection again, and the strictness remains unchanged.
