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.
