This standard is divided into 7 parts of GB/4857. The wood part adopts TS022.7:20100% packaging—a complete and fully loaded transportation and single cargo—quality determination and vibration test standard. Compared with GB/T1857.71992 packaging standard and I502247 standard, the main differences are as follows: For the sake of Chinese users’ habits, the name of the original standard is retained, which is different from many old Chinese standards. Some modifications are made: the relevant explanatory notes are reduced;
In general, the relevant terms are not defined in the international packaging standards, so please eliminate the existing technical definitions! Regarding the provisions of "temperature degradation during test", the relevant contents of the test report have been rectified compared with GB/4857.71992. The changes of this part are as follows: the original applicable to the test packaging in the life scope has been changed to applicable to the return packaging and single light goods! In the requirements for the height difference of the vibration platform, the requirements for the change of the height difference are all in the standard: the provisions for the test receiver have been added;

Test principle
The performance test data of the packaged goods are divided into two parts, and the two test samples are used to generate low-frequency positive vibration. The total humidity is not high, and the test is continuous and the maximum speed is released. The single product is tested in a certain way to change the state of the shock. It is necessary to add a certain load upstream of the product to simulate the situation of the transported goods under the condition of the bottom of the pile.
4 Test equipment
4.1 Vibration table
The vibration table should be of sufficient size and sufficient strength, rigidity and bearing capacity. The test table should be able to ensure that the surface of the vibration table remains horizontal during the new vibration. Its maximum load should be higher than the original test value, and the vibration table should be level, with the horizontal load being c. 3\.
dynamic distribution:
) frame: used to move the test product to both sides during the test: use a mechanical change to prevent the test sample from vibrating during the test: b>
) device used for the return method of the packaging during transportation. In addition, the dynamic platform meets the requirements of 3.3.4.2. The test instrument shall include a speed meter, a position adjuster and an effective belt display or storage device to measure the speed value on the surface of the test sample. The test system shall only meet the test rate of 15% of the specified rate. ：It can also be equipped with a device that can be used to penetrate the inner contents of the device. It can be used as a device. It can be used with the inner materials related to the most sensitive part of the vehicle or the outer surface of the vehicle. The width and model of the vehicle are as follows: GB/T 4857.7-205 5 Test procedures 5.1 Preparation of test samples According to the provisions of GB/1485Y, 17, the test products are tested in detail. 5.2 Numbering of various parts of the test samples According to the provisions of GB/T7.【, the parts of the test products are numbered in reverse order. 5.3 Pretreatment of test samples According to the provisions of GB/T 4857.2, a method is selected to pre-treat the test samples with temperature and humidity. 5.4 Temperature conditions during the test
The test should be carried out under the same conditions as the treatment. If no pretreatment is achieved, the test must be started within 5m of the test sample leaving the pretreatment environment.
5.5 Selection of test strength value
According to the provisions of (48, 18) test intensity value. 5.6 Test steps
5.6.1 Record the temperature of the test environment.
56.2. The test point must be placed on the platform according to the design: the center of gravity of the test sample should be as close to the geometric center of the platform as possible. If the test sample is not fixed on the platform, use the national fence and, if necessary, on the test sample. Add the appropriateness, and the addition procedure shall conform to the provisions of GET4857.3. 5.6.3 Method A 5.6.3.1 Operate the vibration table to produce a speed between 9.3 g and 1.08 g and to keep the test specimen from separating from the table surface. 5.6.3.2 Select a certain (positive or negative) acceleration (see Figure A.1 in Appendix A) and replace the corresponding frequency range with the internal acceleration, and produce a value between 1 and 2 g, and conduct the test. 5.6.4 Method B 5.6.4.1 Operate the vibration table to produce a specified acceleration, which can cause the test specimen to separate from the partition and thus cause the test specimen to separate from the partition and ...2 Select a predetermined amplitude and start vibrating the test sample at a frequency of 2 Hz: gradually increase the frequency until the test sample is about to separate from the vibration table. During this period, the test sample is screened and the minimum displacement number is 1.5 mm. The standard measuring tool has a low area in the center of the test space and the area under test is damaged. This indicates that the test sample is about to separate from the vibration table. 5.6.5 After the test, the damage of the contents shall be inspected according to relevant standards and specifications, and the test report shall be divided into two parts. 6 Test report The test report shall include the following:
