This part is the third part of GB/T 4857.
This part is equivalent to ISO 2234.2000 "packaged complete, full-load transport package and unit cargo static load stacking test".
This part replaces GB/T 4857.3-1992 "Test Method for Static Load Stacking of Packaging and Transport Packages".
The main changes in this section compared with GB/T 4857.3-1992 are as follows.
--- Modify the original only for transport packages in the scope to be suitable for transport packages and unit goods;
--- Added a chapter on terms and definitions, adding the term "test sample";
--- Cancelled 6.1 ~ 6.5 (1992 edition);
--- Added Chapters 6 and 7 (this edition);
--- Modified the content of the test report.
This part is proposed and managed by the National Packaging Standardization Technical Committee (SAC/TC49).

Basic test of packaging and transportation package
Part 3. Static load stacking test method
1 range
This part of GB/T 4857 specifies the main test equipment used for the static load stacking test of transport packages and unit cargoes.
Performance requirements, test procedures, and test report content.
This section is applicable to assess the compressive strength of the transport package and unit cargo during stacking or the protection of the contents. It can be
As a single test, it can also be used as part of a series of tests.

3 Terms and definitions
The following terms and definitions apply to this part of GB/T 4857.
3.1
Completely packed transport packages and unit cargo.
4 Test principle
When testing in one of three test methods, place the test sample on a flat horizontal plane and apply it evenly
Load. The applied load, atmospheric conditions, carrying time, and placement state of the test sample are preset.
Note. If possible, the test sample may be measured for up-and-down skew or left-right deflection during the test.
5 test equipment
5.1 Horizontal plane
The horizontal plane should be flat and hard (the height difference between the highest point and the lowest point does not exceed 2 mm). If it is a concrete floor, its thickness should be
Not less than 150mm.
5.2 Loading method
5.2.1 Method 1. Package Group
Each piece of the package should be identical to the test sample in the test. The number of packages should be the appropriate load for their total mass.
Depending on the amount of charge.
5.2.2 Method 2. Free loading of the tablet
The plate should be able to freely adjust to equilibrium on the test sample along with the appropriate load. The load and loading plate can be one

Overall.
The center of the loading plate is placed in the center of the top of the test sample and should be at least 100 mm larger than the top side of the package. The
The board should be stiff enough not to deform under full load.
Note. This type of load is sometimes referred to as "free load."
5.2.3 Method 3. Guided loading plate
Guided measures are employed to maintain the lower surface of the plate consistently with the appropriate load.
When the loading plate is centered on top of the test sample, its side dimensions should be at least 100 mm larger than the top side of the test sample. The
The board should be stiff enough not to deform under full load.
Note 1. This type of load is sometimes referred to as a “guided load”.
Note 2. If the guiding measures are applied to ensure that the loading plate is level, the measures taken should not cause friction and affect the test results.
5.3 Deviation test method (if necessary for testing)
It should be accurate to ±1mm and can indicate the increase or decrease of the tilt size. In addition, the skew test equipment should meet the requirements of Chapter 8.
Seek tolerance.
5.4 Safety facilities
The stability and safety of the load applied in the test depends not only on the resistance of the test sample, but also on its top surface and loading flatness.
The friction between the bottom surfaces of the plates. To this end, a sound test facility should be provided and the load guaranteed in the event of a hazard
Controlled to prevent injury to nearby people.
6 Preparation of test samples
The prepackage is loaded into the test sample and the package is packaged according to the normal packaging procedure at the time of shipment.
Note. If a simulated content is used, its dimensions and physical properties should be as close as possible to the size and physical properties of the prepackage. Similarly, the packaging method should be
The method used when shipping is the same.
