Packaging test methods and inspection rules
8.1 Packaging test
Newly designed packaging boxes or when there are major changes in the design, process, or materials of the packaging, packaging boxes or packages should be tested. 8.2 Packages
Packaging refers to complete packaging that has been filled with products or product parts and has been encapsulated (this standard specifically refers to hexahedral packaging). 8.3 Packaging test items
Packaging test The items are as follows:
Stacking test and drop test for tile paper boxes, calcium plastic tile boxes, ordinary wooden boxes, and magnesia concrete boxes: a.
Ordinary sliding wooden boxes, sliding wooden magnesia concrete boxes, and bulk lifting test: c. Road transportation test for bare goods.
8.4 Stacking test
8.4.1 Empty boxes are used for the tests of tile paper boxes and calcium plastic tile boxes, and they are bundled according to the packaging technical requirements. Ordinary magnesia concrete boxes are used for the tests of packaging. 8.4.2 Place the tested packaging box on a horizontal ground, and then place a load plate on the box, with the length of the four sides extending out of the top surface of the box not less than 100mm. The load should be evenly applied to the plate, and the added load (including the load plate) is calculated according to the following formula: F=kH-hw×9.8
In the formula: F--load. N;
Stacking height (depending on the storage and transportation conditions, generally not more than 2500mm), mm; h--

JB/T7302-94
8.4.3 After adding load for 1h. Corrugated paper boxes and calcium plastic tile boxes are slightly deformed and qualified; wooden boxes and magnesia concrete boxes are not obviously deformed, and the box body is not damaged.
8.5 Drop test
8.5.1 The weight of the package shall not exceed 100kg. It shall be hoisted to the specified height and freely dropped onto a horizontal concrete floor or thick plate for 6 consecutive drops, with each drop being on the bottom surface of the package. 8.5.2 Drop height
When the weight of the package is not more than .25kg, the drop height is 500mm; when the weight of the package is 26-50kg, the drop height is 400mm; when the weight of the package is 51-75kg, the drop height is 300mm; when the weight of the package is 76-100kg, the drop height is 200mm. If the weight of the package is greater than 100kg, the drop test is not performed. 8.5.3
8.5.4 After the drop test, the packaging box is qualified if there is no obvious damage. 8.6 Judgment of stacking test and drop test
Randomly select 2 pieces from each batch for stacking test and drop test. If 1 piece fails, the packaging box of this type is unqualified. 8.7 Lifting test
8.7.1 The weight of the test product should be within the range of 500~5000kg. Lift at normal speed according to the lifting position. When lifting, make the angle between the lifting rope and the horizontal plane of the box top 45~50° (see Figure 2). After lifting to a certain height (generally not less than 1500mm), use emergency start and brake mode, run up and down, left and right, and then lower to the ground at a uniform speed. Repeat 3 to 5 times. Figure 2
8.7.2 After the test, the packaging should be free of damage or obvious deformation to be qualified. 8.7.3 Select 2 pieces for lifting test. If 1 piece fails, the packaging of this type is unqualified. 8.8 Highway transportation test
8.8.1 The weight of the test product is greater than 5000kg. The product is placed in the middle and rear of a truck and fixed according to the product packaging technical requirements. It is driven on the intermediate road surface of a third-level highway at a speed of 25-40km/h for 200km. After the transportation test, the local packaging or packaging box has no obvious damage or deformation, and the product in the box is not loose, damaged or obviously shifted. It is qualified. 8.8.2 The highway transportation test is only performed once. If it fails, the packaging is judged as unqualified. Additional instructions:
