B/T22939.5—2025， Part 5: Special Requirements for Electric Washing Machines and Dryers "is designed and manufactured for packaging and carrying reliability testing of washing machines, dryers, and integrated washing and drying machines. It simulates the vertical impact and carrying load that products experience during storage, handling, and stacking, verifies the strength of product packaging structure and the 

overall impact resistance of the machine, and ensures product transportation safety. We have tested the vibration impact in the field using the principle of high-frequency vibration. The test bench adopts a profile steel structure and a C # groove iron chassis, effectively eliminating vibration noise during the testing process through a vibration reducing structure. 17 inch touch industrial control computer and our independently 

developed upper computer for program control. Carrying a testing machine.

The contact area between the backpack testing machine and the test prototype is made of wear-resistant nylon plate, rubber with a thickness of (5 ± 1) mm and an area of 600mm × 500mm, with an impact square

The impact waveform is a half sine wave in the direction perpendicular to the horizontal direction. The testing platform adopts an electric lifting structure, and a manual lifting mechanism is used to lift and pull the test packaging. The quick locking is a manual locking and pneumatic rotating test sample testing angle. A locking angle plate is used to effectively prevent the test sample from rolling, falling, and falling off.
