Recently, the TONEXUS catalyst laboratory successfully passed the assessment of the China National Accreditation Service for Conformity Assessment (CNAS) and obtained national laboratory accreditation. Since the start of its CNAS trial operation in April 2024, the laboratory underwent nearly a year and a half of solid preparation and system improvement, and successfully completed the on-site assessment in June 2025. Throughout the preparation process, the TONEXUS laboratory team worked with rigor and precision, overcoming multiple technical challenges, continuously enhancing its quality management system, and ultimately passing the accreditation in a single attempt.
CNAS is the only laboratory accreditation body in China, and its certification is highly authoritative and internationally recognized. The accreditation signifies that the TONEXUS laboratory has met national and international standards in management systems, technical competence, and testing capability. The test data it produces will now be recognized by multiple economies worldwide. This not only significantly enhances the company’s credibility within the industry but also provides strong support for further market expansion and strengthening core competitiveness.
