The necessity of mechanical strength testing for electric blankets
Electric blankets are popular household items, especially in colder climates where they provide the ability to stay warm and cosy on cold nights. However, due to safety concerns such as electric shock, overheating, and fire, manufacturers must ensure that their electric blankets are safe and reliable for consumers. A key step in ensuring safety is to conduct mechanical strength testing. Mechanical strength tests assess an electric blanket's ability to withstand forces and pressures during use. These tests involve subjecting the electric blanket to different forces such as tension, compression, bending and twisting. The purpose of these tests is to assess the durability and resistance to mechanical stress of the electric blanket.
Manufacturers must comply with international safety standards, such as GB and the International Electrotechnical Commission (IEC), and follow these standards when designing and manufacturing electric blankets. These standards provide guidance on mechanical strength testing to ensure the safety of electric blankets.
SH9910 electric blanket bending tester is designed and manufactured according to the requirements of UL130 No. 28, this tester is mainly used for bending test of electric heating pad.
Technical Parameters：
1.Power supply: AC220V/10A
2.Bending speed range: 10-30 times / min .
3.Counting range: 0~99999 (can be preset), each station counts independently, using the load current sampling method of counting, when a test piece occurs when the circuit is broken, the test piece corresponding to the counter stops counting. When the test reaches the preset counter, the equipment stops working automatically. The equipment has overload and overcurrent load and leakage protection.
4.Bending angle:90°
5.Weight of weights: 1lb, 2 pcs in total
6.Control system: PLC + touch screen.
7.Data with power-down protection
8.Work stations: 2
9.Current Determination Abnormal Time: 0~999S can be set, any load disconnection during the test, the device stops the test, the count is maintained.
10.Maximum size of test piece: 800*800mm
11.Domestic high-quality electrical components
12.Bending bar can not be rotated
13.Floor-standing deluxe design, high-grade aluminium alloy structure.
14.Overall size: about L2100*W1140*1500mm
In conclusion, mechanical strength testing is essential to ensure the safety and reliability of electric blankets. By subjecting electric blankets to different forces and stresses, manufacturers can assess their durability and resistance to mechanical stress. Compliance with international safety standards is essential to ensure that electric blankets are safe and do not pose any risk to consumers.
