Common test standards for transport packaging
Nowadays, many excellent international companies have a relatively scientific and strict standard for the inspection of transportation and packaging. The tests conducted by Tianyi on the transportation and packaging are based on the current advanced and universal international standards. These standard tests are usually carried out in design-guided tests, transport routine tests, environmental transport tests, etc.:
First, design guidance test
The purpose of the design-guided test is primarily to test the basis of product performance and packaging design. The test can reflect the performance and easily damaged parts of the product through scientific data, and can be compensated and improved in the packaging design. A comprehensive investigation can be carried out by both the frequency sweep test and the impact fragility test.
1. Sweep test test method reference ASTM D3580
The frequency sweep test of the tested object can be carried out without packaging and packaging. The frequency response of important parts of the sample is mainly investigated. By installing the sensor on the important component and drawing the graph, the resonance frequency of the component can be analyzed. The frequency range of the sweep frequency can be from 2 Hz to 200 Hz to 2 Hz, and the input acceleration is 0.5 g. After the resonance frequency is obtained, the input acceleration can be further increased, and then the original acceleration of 2 times is input at the resonance frequency (1.0). g) Vibration for 5 minutes.
2, impact fragility test test method reference ASTM3332
The test product does not need to be packaged. Through the inspection of the impact fragility of the product, the weaknesses and defects of the product can be further discovered, the characteristics of the product are understood, the inherent quality of the product is improved, and an important theoretical basis is provided for the packaging design. Tianshen can be tested according to the requirements of the design code of home appliances. The product needs to withstand the test under the half sine wave speed change rate greater than 170cm / s, the impact square wave acceleration is greater than 36g.
The above two tests should be carried out at the beginning of the design. If problems are found and cannot be tested, they should be improved immediately from both the product and packaging aspects. Don't wait for the product to be finalized and make changes, and the design cost required at that time will be huge.
Second, the product transport test
We should determine the corresponding test plan according to the sales direction of the product, the logistics environment of the product, and refine and formulate the corresponding transportation test standard of the enterprise, which should meet the quality requirements and transportation requirements of foreign enterprises, and run through the product development. With the final acceptance criteria of the retrofit, the sales of the product should be intact in the hands of the end user, and the proportion of damage caused by the transportation of the product should be controlled to a very small extent.
The specific implementation scheme is as follows:
First of all, we can classify according to the weight of the product. The weight of more than 50 kg and less than 50 kg should be investigated separately, because different products will be damaged and destroyed according to the statistical and foreign related transport test standard weight. The way is different, so it is necessary to classify. There are also product transportation standards that should be representative, adapt to the requirements of the international logistics environment, and meet the requirements of foreign machinery handling.
1, small products <50 kg
The test plan should include storage test, mechanical handling test, vehicle transportation vibration test, airborne vibration test, tipping test, and drop test. The test requires 4 samples to complete all tests.
A, storage stacking test test method reference ASTM D-642
