This standard specifies the main performance requirements, test procedures and test report contents of the test equipment used in the overturn test of transport packages, and can be used to evaluate the ability of transport packages to withstand impact when they are overturned and the ability of the packaging to protect the contents. It can be used as a single test or as part of a series of tests on packages. This standard is applicable to packages with a smaller bottom size relative to the height during storage and transportation, and is generally used for packages with a ratio of the longest side to the shortest side of less than three to one.

GB/T 4857.14—1999
This standard is a revision of GB/T4857.14-1989 based on ISO8768:1987 “Tip-over test for fully packed transport packages”, and is equivalent to the international standard in terms of technical content. This standard is mainly used for packages that may tip over during storage and transportation. These packages mainly refer to packages whose height dimensions are relatively large relative to the bottom dimensions, and also include those transport packages whose height dimensions are relatively small but whose bottom dimensions are used as the smaller surface in order to save storage and transportation space.
When revising GB/T4857.14-1989 based on international standards, considering the specific conditions of my country and the specific problems in use, the “tip-over sequence and tip-over times” will still appear in the form of Appendix A (indicative appendix). This standard will replace GB/T4857.14—1989 from the date of implementation. Appendix A of this standard is an indicative appendix.
This standard was proposed by China National Packaging Corporation. This standard was approved by the National Packaging Standardization Technical Committee. The main drafting units of this standard are: Mechanical Science Research Institute of the Ministry of Machinery Industry, the Packaging Office of the PLA, Beiren Group Corporation, and China Packaging Research and Testing Center.
The main drafters of this standard are: Huang Xue, Guo Baohua, Zhang Xiaojian, Wang Ruiqi, Wei Lingchen, and Xu Weifeng. 292

This standard specifies the main performance requirements, test procedures and test report contents of the test equipment used in the toppling test of transport packages. It can be used to evaluate the ability of transport packages to withstand impact when they are tipped over and the protection of the packaging to the contents. It can be used as a single test or as part of a series of tests on packages. This standard is applicable to the case where the bottom size of the package is relatively small relative to the height during storage and transportation. Generally, it is applicable to packages with a ratio of the longest side to the shortest side of not less than three to one. 2 Referenced standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB/T4857.1-1992 Method of marking various parts during testing of packaging and transportation packages GB/T4857.2-1992 Temperature and humidity adjustment treatment of packaging and transportation packages GB/T4857.17-1992 General principles for compiling performance test outlines for packaging and transportation packages 3 Test principle
Place the test sample on the impact table in a predetermined state, and gradually apply horizontal force at an appropriate position above its center of gravity to make it tilt freely along the bottom edge.
4 Test equipment
4.1 Impact table
The impact table should be a horizontal plane, and the impact table should have sufficient mass and rigidity. The table should not move or deform during the test. In general, the impact surface should meet the following requirements: a) Flatness: The horizontal height difference between any two points on the impact table should not exceed 2mm b) Sufficient rigidity: When a 10kg mass block is placed on any 100mm2 area on the impact table, the deformation shall not exceed 0.1 mm;
c) Large enough area: Ensure that the test sample falls completely on the impact table; d) A whole piece: The mass is at least 50 times that of the heaviest test sample. Note: If a concrete floor is used as the impact surface, its thickness must be at least 150mm to meet the above requirements. 4.2 The force-applying device
should have the ability to apply sufficient horizontal impact force above the center of gravity of the test sample, and when the test sample is overturned, it shall not cause the test sample to slide on the impact table.
Approved by the State Administration of Quality and Technical Supervision on September 7, 1999, and implemented on February 1, 2000
5 Test procedures
5.1 Preparation of test samples
GB/T 4857.14-1999
Prepare test samples in accordance with the requirements of GB/T4857.17. 5.2 Numbering of test sample parts
Number each part of the test sample in accordance with the provisions of GB/T4857.1. 5.3 Pretreatment of test samples
Select a condition for temperature and humidity pretreatment of the test sample in accordance with the provisions of GB/T4857.2. 5.4 Temperature and humidity conditions during the test
The test should be carried out under the same temperature and humidity conditions as the pretreatment. If the pretreatment conditions cannot be met, the test must be started within 5 minutes after the test sample leaves the pretreatment conditions.
5.5 Selection of test strength value
For the selection of test strength value, please refer to Appendix A.
5.6 Test steps
5.6.1 Place the test sample on the impact table in the predetermined state. For the slender test sample, it should be placed in the normal state and its side should be tilted (see Figure 1). For the flat test sample or the test sample with uncertain bottom surface, the smaller surface should be used as the bottom surface and its larger surface should be tilted (see Figure 2).
Figure 1 Slender test sample
(The height is relatively large relative to the length and width of the bottom surface)1
Figure 2 Flat test sample
(The height is relatively small relative to the length and width of the bottom surface, but it is placed on one side to save space)5.6.2 Apply horizontal force at an appropriate position higher than the center of gravity of the test sample or its upper edge. Gradually increase the force to make the test sample tilt around the bottom surface until it reaches balance. Then make it lose balance without impact and tilt freely onto the impact table. 294
GB/T 4857.14—1999
5.6.3 Check the test samples and record the relevant test phenomena. 5.6.4 Select the test intensity according to the requirements of 5.5, repeat the steps of 5.6.1~5.6.3 to carry out the test in sequence. After the test, check the damage of the packaging and the contents according to the relevant standards or regulations, and analyze the test results. 6 Test report

Order and number of overturning
The order and number of overturning in the test using this standard are determined by many factors, such as the purpose of the test, the characteristics of the contents (weight, volume, type, etc.), and the circulation environment such as storage, transportation, and loading and unloading. When there are professional product standards, it can be carried out in accordance with the relevant regulations, or in accordance with the agreement between the two parties. A1 The number of test samples (packages of the same product) is generally not less than 3. A2 corresponds to Figures 1 and 2. Table A1 and Table A2 respectively give two tilting sequences. The tilting sequence and number of tiltings are generally required to complete a cycle given in Table A1 or Table A2. A3
