As long as the personnel carry out work according to the system strictly, the laboratory’s technical capacity will be guaranteed. The test/calibration services provided by the laboratory to the customer can claim to be accordance with the international standards.
CNAS is the only laboratory accreditation institute in China; it bears nationwide laboratories for ISO17025 standard approval. All calibration and test laboratories can adopt and implement the ISO17025 standard. In accordance with international practice, data provided by the ISO17025 standard laboratory have legal effect and get international recognized. At present, China has more than 1,000 laboratories that get through the ISO17025 standard certification. Through the implementation of standard to improve the accuracy of the test data and results and expand the laboratory’s reputation, thereby greatly improve the economic and social benefits.
All Lisun products can be sent to CNAS laboratory to do calibration and get CNAS calibration certificate, which meets ISO17025 standard.
