This section GB/T 44857 Part of.

This part identical with ISO 12048:1994 "Packaging intact, filled transport packages and using the compression press to heap Code experiment. " this part of ISO 12048:1994 as compared to the main differences are as follows.

--- The Note 3, 4, Note 5, Note 6 to formal terms (Excerpts 7.3.1,7.3.2,7.3.5,7.3.6);

--- Deletion of Appendix B (for reference only directory. Standard ISO 2234. 1985), placed in Chapter 2.

This Part replaces GB/T 4857.4-1992 "Transport packages Pressure test method" and GB/T 4857.16-1990 "package Loaded transport package stacking test using "pressure tester's.

This portion of the GB/T 4857.4-1992 and GB/T 4857.16-1990 compared to the main changes are as follows.

--- Combined the two standards (GB/T 4857.4-1992 Version and GB/T 4857.16-1990 version) Test principle;

--- Combined the two standards (GB/T version 4857.4-1992 and GB/T 4857.16-1990 Version) testing machine platen requirements, Georgia Type have been adjusted accordingly;

--- Canceled 5.1 to 5.5 (1992 edition), to Chapters 5 and 6 (edition);

--- Combined the two standards (GB/T version 4857.4-1992 and GB/T 4857.16-1990 edition) Test methods, increased

Table 1;

--- Modify the contents of the test report;

GB/T 4857.4-2008/ISO 12048:1994

--- Increased measurement package deformation - load Method Example (see Appendix A).

1 Scope

This section GB/T 4857 provisions for transport packages pressure test using the same test equipment and test stacking test Principle experiment, the contents of the device performance, test procedures and test reports with.

This section applies to assess transport package when subjected to pressure, compressive strength and packaging of contents protection. It can make A single experiment can also be used as part of a series of tests.

3 Test principle

The test sample is placed between the press platen, and then choose either method.

a) In the case of the compressive strength test, carried out until the pressure until the test sample is damaged or reaches a predetermined load and displacement values.

b) In the case of stacking test, until a predetermined load is applied to the test sample is damaged or until a predetermined time elapses.
