variable frequency conversion test method compared with 15818 standard, the following differences: - According to Chinese pregnancy habits, some traceability formats have been modified; reduce the relevant explanatory samples,
Due to the definition of relevant technical spectrum in the packaging technical standard, the provisions of "test resistance or temperature conditions" with American definition were cancelled, and the requirements were widened compared with the standard. The appendix A (for other users to determine the reporting time) was added. According to the trend of GB 4857 standard and the actual use conditions, the relevant contents of the test report were reviewed. Compared with GB 4857, 10-1992, the main changes are as follows: the original "only for transport packaging" was used in the specification. The modification of the fire applicable to the thirteen transport packaging units will be higher than the original requirements on the table surface! The standard modification is effective for the corner doctor to accept the chemical requirements of the standard to add the current provisions of the time-pass test positioner:

The test sample is vibrated. Within a specified time, the test sample is subjected to a predetermined vibration at a frequency between 122 and 1) Hz. If necessary, a certain load can be added to the test sample to simulate the environment of the transport package being subjected to a static vibration at the bottom of the stack.
4 Test equipment
4.1 Vibration table
The vibration table should have sufficient size, strength, rigidity and or capacity: the structure should be able to ensure that the vibration table surface remains horizontal during vibration, and its resonance rate should be reduced to a maximum test frequency. The vibration table should be level and the maximum angle change between the seat and the required level is 03°. The vibration table can be equipped with various types of
2) Low frame to prevent the test sample from falling to both ends and sides during vertical test; 3) High frame to prevent the test sample from shifting when driven by the load on the test product; 4) Used to fix the packaged goods during transportation. In addition, the vibration table must comply with the requirements specified in 5.5.3. 4.2 Receivers
