Electric toothbrush test certification

Basic introduction

The electric toothbrush is a relatively new product. The new product only in recent years has become a new technology product for oral health care. Compared with ordinary toothbrush, electric toothbrush is more scientific and effective. It can remove dental plaque more thoroughly and reduce oral diseases such as gingivitis and periodontal disease. It is also a daily necessities that are generally popular in many countries in Europe and the United States. The electric toothbrush causes high-frequency vibration of the brush head through the rapid rotation or vibration of the motor core, which instantly breaks down the toothpaste into fine foam and cleans the teeth deeply. With the popularity of products, the quality inspection report of electric toothbrushes has also become a passport to enter the market. When electric toothbrushes enter Tmall Mall, they also need to submit a quality inspection report that meets the requirements; product inspection also requires a quality inspection report. The third-party testing and appraisal agency designated by the North Testing and Inspection City can provide you with the CNAS and CMA electric toothbrush quality inspection reports.
