In the field of transport packaging, standardized testing plays a crucial role in ensuring product safety and quality during shipping. One widely recognized standard is GB/T 4122.5-2002, which outlines common test methods for transport packaging. Many leading international companies have developed rigorous and scientific testing protocols to evaluate their packaging solutions. At Tianyi, we follow advanced and globally accepted standards when conducting tests on our transport packaging.
These tests are typically divided into several categories, including design-guided testing, routine transport testing, and environmental simulation testing. Each stage helps identify potential weaknesses and improve the overall performance of the packaging system.
First, design-guided testing focuses on evaluating the product’s performance and identifying critical points that may be vulnerable during transportation. This type of test provides valuable data that can be used to refine both the product and its packaging. Two key tests often used in this phase are frequency sweep testing and impact fragility testing.
The frequency sweep test, based on ASTM D3580, involves analyzing the frequency response of critical components. Sensors are attached to these parts, and the results are visualized through graphs. The frequency range usually spans from 2 Hz to 200 Hz, with an initial input acceleration of 0.5 g. If resonance is detected, the acceleration is increased to 1.0 g at the resonant frequency for 5 minutes to simulate real-world conditions.
Another essential test is the impact fragility test, following ASTM D3332. This test assesses the product's resistance to impact without any packaging. It helps uncover hidden flaws and improves the product's inherent quality. For example, home appliance products must withstand a half-sine wave speed change rate of over 170 cm/s or an impact square wave acceleration exceeding 36g. These tests are conducted early in the design phase to avoid costly revisions later.
Next, the product transport test involves developing a tailored testing plan based on the product’s sales region and logistics environment. We aim to meet international quality and transportation standards while ensuring that the product arrives intact at the end user. This approach minimizes damage during transit and enhances customer satisfaction.
To implement this, we classify products by weight. Products weighing less than 50 kg require different testing procedures compared to heavier items. This classification ensures that the testing aligns with statistical data and global standards.
For small products under 50 kg, the test plan includes Storage stacking, mechanical handling, vehicle vibration, airborne vibration, tipping, and drop tests. Four samples are tested to ensure consistency and reliability. The storage stacking test, referenced from ASTM D-642, calculates the load capacity based on the product’s weight (L = W). This helps determine how well the packaging can handle stacking during storage and transport.
By following these comprehensive testing procedures, we ensure that our packaging solutions are not only safe but also efficient and cost-effective. Regular testing throughout the product lifecycle allows us to continuously improve and adapt to changing market demands.
