Product No: LS-B77
The LS-B77 Vacuum Cleaner Tube Torsion Tester is designed according to the requirements of IEC 60335-2-2 Clause 21.104 (GB/T 4706.7 Clause 21.104) to test the torsion resistance of vacuum cleaner hoses. During the test, one end of the hose is fixed to the rotating clamp of the equipment, while the other end is suspended. Each cycle consists of five forward rotations and five reverse rotations at a speed of 10 revolutions per minute (r/min), for a total of 20 cycles. After the test, the sample undergoes an electrical strength test to ensure its durability and safety.
