Foreword

This revised standard adopts the American Society for Testing and Materials standard ASTMD1596-1997 "Test Method for packaging material damping properties." This compared to a standard American Society for Testing and Materials standard ASTMD1596-1997, the main differences are as follows. --- Revised measure the buffer material thickness compressive load capacity; --- Modify the cushioning material measuring length, width, thickness accuracy value; --- Expanding the application conditions test system; --- Test method for increasing the use of compression box. This standard replaces GB/T 8167-1987 "package cushioning material dynamic compression test method." This standard compared with GB/T 8167-1987, the main changes are as follows. --- Refine the test equipment for dynamic compression test requirements to be met; --- Provides for random test sample requirements; --- Modify the number of tests with the test sample; --- Increasing the test sample sizes recommended; --- Increasing the speed and height of the drop test calculation method; --- Increasing the thickness measurements of the test requirements in the test report. The Standard Appendix A, Appendix B is an informative annex. This standard by the National Packaging Standardization Technical Committee (SAC/TC49) and focal points. This standard was drafted. the machine Productivity Promotion Center, Shenzhen MYS Environmental Protection Technology Co., Ltd, China Export Commodities Packaging graduate School. The main drafters of this standard. yellow snow, Liu Ping, Cai Shao Ling, Li Jianhua, Zhang Jian. This standard replaces the standards previously issued as follows. --- GB/T 8167-1987. Packaging cushioning material Dynamic Compression Test Method

1 Scope

This standard specifies the packaging cushioning material dynamic compression test principle test methods, test equipment, test samples, test procedures and test Inspection reports. This standard applies to the assessment of properties and buffer material buffer contents Product protection under the impact of a role in the distribution process. This standard applies to the shape of the packaging with cushioning material may be massive, flaky, filamentous, granular and molded parts in the form of EPS, EPE And other soft, hard cushion material not suitable for corrugated board, EPE film, metal springs and shock-proof rubber.

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 4857.2 Basic tests for transport packages - Part 2. Temperature and humidity adjustment process (GB/T 4857.2-2005, ISO 2233.2000, MOD)

3 Test principle

With the free fall of the hammer impact load is applied to the packaging cushioning materials, calculate the acceleration and static dynamic compressive stress determined cushioning material Reduced performance. Test results are expressed as dynamic cushioning material compression characteristic curve.

4 Test Equipment

4.1 Testing Machine 4.1.1 The test machine shall have a free fall of the base weight and a larger mass. 4.1.2 The weight should be accompanied by an acceleration sensor. 4.1.3 The weight should have a flat and can be completely covered by the impact surface of the test sample, the quality of the hammer can be adjusted, if a plurality of weight Mass composition, it should be fixed as a whole. 4.1.4 The weight should be hard, and has sufficient rigidity to ensure that the process does not impact due to the weight of their own vibration waveform leaving the test distortion. 4.1.5 hammer impact test machine and the surface should be parallel to the base surface, and a predetermined speed impact test sample, impact velocity error should not exceed ± 2%. Meanwhile, the weight should be at intervals of not less than 1min continuous shock. 4.1.6 Test machine base should have sufficient rigidity, the maximum weight of the impact face shall be less than the base surface of the base quality testing machine, testing machine At least 50 times the maximum weight quality. 4.1.7 If the mass of the test machine base is less than 50 times the maximum mass of the hammer, hammer width, height should be less than half the length of the base. 4.2 Test System Test system includes an acceleration sensor, amplifier, display or recording devices. Test systems should have enough frequency response, measured in Amount within the range of accuracy of the test system should be within ± 5% of.

5 test sample

5.1 Sampling Test samples should be placed in a random sample of more than 24h finished when its size can not meet the stipulated requirements, allowing production ......
