IEC 60335-2-81 Figure 101 Equipment For The Flexing Test For Foot Warmers
Product overview:
The foot warmers flexing test equipment is designed and manufactured according to IEC 60335-2-81 clause 21.101 and figure 101.
This test equipment is used to test whether the foot area of the foot warmer or the heating area of the heating mat can withstand the mechanical strength. After the test equipment is started, the testing will be started automatically, and the testing will be stopped after reaching the set number of times. It adopts button control and digital display, the drop is achieved at a rate of six times per minute automatically by electromagnet adsorption or release.
Technical Parameters:
| Items | Specifications |
| Power supply | Match client’s local power supply requirements |
| Test times | 0～9999,can be set on the touch screen. Default 1000 times. |
| Drop frequency | 6 times / min, can be preset |
| Load weight | 30KG (total mass of weight, board and connecting supports) |
| Drop height | 200mm |
| Plywood board | Dimensions approximately 300*150*20mm with rounded edges |
| Operation mode | The electromagnet absorbs the weight and lifts it to 200mm height and then automatically releases the weight to impact on sample |
| Alarm function | With power-on test function, it can realize the alarm function of disconnecting the circuit load of the sample |
| Control | This equipment adopts button control and digital display |
Test Requirements:
A plywood board, having dimensions approximately 300mm x 150mm x 20mm with rounded edges, is placed in the leg section of the foot warmer as shown in Figure 101. A load of 30 kg is placed on the board, which is allowed to drop freely from a height of 200 mm above the base, so that the leg section is flexed and the appliance is compressed between the board and the supporting surfave. The total mass of the board, its movable support and the load is 30 kg. If the foot warmer does not have a leg section, the board is allowed to fall onto the top surface.
The test is carried out 1 000 times at a rate of six times per minute.
The test shall not result in
- damage to the enclosure or displacement of heating elements to such an extent that compliance with the standard is impaired;
- open-circuiting of heating elements or controls;
- breackage of more than 10% of the strands of internal wiring;
- failure of constructional stitchinh, or breakage of glued or welded joints, to such an extent that compliance with the standard is impaired.
