Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 14745-1993 "packaging cushioning material creep characteristics test method", and GB/T 14745-1993 phase
Than the main technical changes are as follows.
--- Modify the standard name;
--- Modify the scope of the statement (see Chapter 1,.1993 edition Chapter 1);
--- Added "creep" "time - creep curve" terms and definitions (see 3.1, 3.2);
--- Modify the test principle statement (see Chapter 4,.1993 edition Chapter 4);
--- Modify the requirements of the test equipment (see Chapter 5, Chapter 5 of the.1993 edition);
--- Modify the sample size and number (see Chapter 6,.1993 edition of 6.2, 6.3);
--- Modify the test method for sample size (see 8.1, 8.2, 8.3,.1993 edition 7.2.1, 7.2.2, 7.2.3);
--- Modify the sample pretreatment and test conditions (see 7.1, 7.2,.1993 version 7.1);
--- Increasing the weight of the mass formula (see 9.1);
--- Removed the original A method of test step 7.4.1.3 (see.1993 edition of 7.4.1.3);
--- Deleted the original 7.4.2B test (see.1993 version 7.4.2);
--- Remove the cylinder density, static stress, static stress strain formula (see.1993 edition of 7.5.1.2, 7.5.2, 7.5.3);
--- Modify the part of the test report (see Chapter 11, Chapter 8 of the.1993 edition);
--- Removed Appendix A (see the.1993 edition of Appendix A).

Test methods for creep characteristics of cushioning materials for packaging
1 Scope
This standard specifies the test method of creep characteristics of cushioning materials for packaging.
This standard applies to flake, plate or block packaging cushioning material.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 4122.3 Packaging terminology part 3. Protection
Packaging - Transport packages - Basic test - Part 2. Temperature and humidity conditioning
3 Terms and definitions
GB/T 4122.3 defined and the following terms and definitions apply to this document.
3.1
Creep creep
Under certain temperature and humidity and constant external force, the deformation of the material gradually increases with time.
3.2
Time - creep curve creepversustimecurve
Taking the test time as the abscissa, the creep amount of the material during the test is plotted on the ordinate.
4 test principle
The load and the movable platen placed on the test sample to simulate the static constant compressive load, by measuring the thickness of the sample with time to change
Characterize the creep properties of cushioning materials.
5 test equipment
5.1 test stand
Test rack should meet the following requirements.
a) The test stand includes a rigid base plate and a movable platen. The movable platen is capable of placing weights on the platen to apply pressure, and the applied load should be at
The geometric center of the moving platen. Activities pressure plate should not be affected by any external force;
b) The minimum size of the base plate and movable platen is 120 mm × 120 mm.
5.2 with weight
Counterweight should be a flat surface of the cube structure should be made of metal to ensure the rigidity and strength of the normal test, the quality of fine
Indeed 0.1kg.
