With the development of the times, there is an increasing demand for the accuracy and universality of calibration/detection results from the market and customers. However, the accuracy and reliability of internal laboratory calibration/detection data are often suspected by clients and consumers. More and more laboratories are gradually recognizing the importance of laboratory accreditation, its promotional effect on brand value, and the influence it brings to the enterprise. Laboratories provide reliable data in product development, design verification, manufacturing processes, and instrument calibration, which also significantly saves the enterprise's testing costs and time.

In accordance with the rules of the China National Accreditation Service for Conformity Assessment (CNAS), laboratories that have received national recognition have their technical capabilities and data recognized by the state. Laboratory accreditation is a formal recognition that a calibration/detection laboratory is capable of performing calibration/detection. It serves as the foundation for establishing market credibility for the company where the laboratory is located, acts as a "passport" to enter the calibration and detection market, and is also a bridge for laboratories to gain international recognition.
