What is the difference between LVD and EMC testing in CE certification?

LVD testing evaluates the electrical safety of the device, ensuring there is no risk of electric shock, fire, or mechanical hazards under normal and fault conditions. EMC testing ensures the back massager does not emit excessive electromagnetic interference that could disrupt other devices, and that it is immune to external interference.

How long does the CE certification process take for a new back massager?

The typical CE certification timeline for a new model is 4-6 weeks, including the time required for laboratory testing and technical file compilation. If the design requires significant modifications to pass EN 60335-1, this timeline can extend.

Can a factory provide a CE certificate if the product is modified after testing?

No. A valid certification is only applicable to the exact product configuration that was tested. If an OEM back massager manufacturer China changes the motor, PCB layout, or plastic material after the initial test, the original certificate becomes invalid, and the product must be re-tested or assessed for equivalence by a qualified engineer.
