What Features Should A High-quality Suitcase Have

When traveling, a sturdy and durable suitcase is essential. It offers greater practicality and can withstand the bumps and knocks that come with rushing to catch a flight. The quality of a suitcase can be assessed by focusing on the following key indicators:
Telescopic Handle Fatigue Resistance
Under specified extension and retraction frequencies, the handle's fatigue resistance, structural integrity, and the durability of the locking mechanism are tested by continuously opening and closing the handle, as well as repeatedly extending and retracting it. After 3,000 cycles of opening and closing as per regulations, the handle should show no signs of deformation, jamming, or loosening.
Rolling Performance
The rolling performance of the wheels is evaluated based on their wear resistance, and the quality of this performance directly determines the distance the luggage can travel.

After testing, the wheels should rotate smoothly without jamming or deformation; the wheel frames and axles should show no deformation or cracking; wheel wear does not exceed 2 millimeters; the telescopic handle extends and retracts smoothly, without deformation, looseness, or jamming; the joints between the telescopic handle, side straps, and side handles and the suitcase body show no cracks or loosening; and the suitcase lock opens normally. When purchasing, a simple way to test this is to place the suitcase on the ground and pull it back and forth; the wheels should roll smoothly, and the fit between the wheels and axles should be neither too tight nor too loose.
Vibration and Impact Resistance
Vibration and impact resistance is a key indicator of a suitcase's quality. After loading the suitcase with a specified weight, it is lifted using the handle or a fully extended telescopic handle. It is then dropped at a specified speed and under its own weight within a defined range, causing the suitcase to undergo impact and vibration as the springs absorb and release the force. This tests the quality of the handle, telescopic handle, and the suitcase body.

Generally, the handles of soft-sided suitcases must undergo 400 oscillation impact tests, while those of hard-sided suitcases must undergo 300 tests. If the suitcase has side handles, these must also undergo 300 oscillation impact tests. When testing the telescopic handle's resistance to oscillation impact, the number of tests is determined by the suitcase's dimensions: if the case dimensions do not exceed 610 mm, 500 tests are required; if the dimensions exceed 610 mm, 300 cycles are required.
Drop Resistance
During travel, improper placement of luggage can lead to a risk of dropping. According to regulations, the drop platform height is adjusted so that the bottom of the sample is 900 mm above the impact surface. The suitcase is dropped once with both the main handle and side handles facing upward. After testing, the suitcase body and all components should show no damage or breakage.
Other Criteria
Additional considerations include the presence of carcinogenic azo dyes, formaldehyde, resistance to ball impact, resistance to drum impact, and lock durability. For specific details, request test reports from authoritative institutions from the seller.

In summary, as long as your suitcase meets most of the above criteria, it will go a long way toward reducing the burden of storing and carrying your luggage while traveling. These features can also serve as a useful guide when selecting a suitcase in the future.
