First, fix the plywood part of the specimen to the base fixture of the tension and compression testing machine, then fix the connecting member of the specimen to the top fixture of the tension and compression testing machine, and ensure that the horizontal direction of the plywood part of the specimen is parallel to the force direction. The moving speed of the testing machine should be 15nm/min. Until the metal connecting member is separated from the plywood, record the maximum tensile force at this time. 6.10.3 Longitudinal connection strength test.
First, fix the plywood part of the specimen to the base fixture of the tension and compression testing machine, then fix the connecting member of the specimen to the top fixture of the tension and compression testing machine, and ensure that the horizontal direction of the plywood part of the specimen is perpendicular to the force direction, as shown in Figure 3. The moving speed of the testing machine should be 15mm/min.

6.11 Overall compression test
Take 3 test samples and carry out according to the provisions of GB/T4857.4 and 5.6.1: The stacking load is calculated according to the following formula:
M, = K·(H/h -1)M

Wherein:
M—stacking load;
Deterioration coefficient of package, not less than 4;
H—stacking height, m generally not less than 3.5m; h-height of sample box, m;
M,-mass of sample box and contents, kg;
H/n is rounded up.
6.12 Offset pressure test
Take 3 test samples and conduct the test in accordance with the provisions of 5.6.1 of GB/T4857.4. Place a pallet box or a Shantong box with the same structure as the bottom of the test sample on the test sample. The placement position is 1/3L (L is the length) in the length direction and 50mm in the width direction from the edge of the sample box. Apply pressure to reach the stacking load calculated in 6.11. The test is terminated when the repulsion load reaches the predetermined value or the sample box is damaged. The deformation of the sample at this time is recorded. 6.13 Local pressure test
Take 3 test samples and conduct the test in accordance with the provisions of 5.6.1 of GB/T4857.4. Place the sample box in the center of the lower pressure plate in the predetermined state, and then place a square rigid load head with a plane size of 100mm×100mm×100mm at the center of the top of the sample box. When the compression load reaches the rated value of 2kV or the sample box is damaged, the test is terminated and the deformation of the sample is recorded. 6.14 Drop test
Take 3 test samples for drop test.
When the mass of the package is less than 100kg, the test shall be carried out in accordance with the provisions of 5.6 of GB/T4857.5. The test shall be carried out with real objects or simulants. When using simulants, the weight shall be balanced according to the nominal load: the drop locations are the bottom surface, four bottom corners, and four bottom shuttles, each falling once, and the drop height is 7. After the test, check whether the sample is obviously damaged and whether the simulants inside are scattered. Table 7 Drop height of face, edge and corner
