Scope
GB/T 8167-2008 is the English-translated version of 包装用缓冲材料动态压缩试验方法.
GB/T 8167-2008 is the Chinese standard "Testing method of dynamic compression for packaging cushioning materials". Its scope clause reads: 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. Its clauses include test principle; test equipment; test sample.

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 […]
