YONZ Institute Testing Center Earns CNAS Accreditation, Reinforcing Industry Leadership

August 21 – The Testing Center of YONZ Green Energy Materials Research Institute (Changzhou) Co., Ltd. has been awarded CNAS accreditation (Certificate No.: CNAS L23913) by the China National Accreditation Service for Conformity Assessment. This milestone achievement marks official recognition of the center’s technical competence and quality management in aluminum alloy material testing, elevating it to the status of a nationally accredited laboratory.

Since its establishment on January 31, 2024, the Testing Center has operated under a robust quality management system compliant with ISO/IEC 17025:2017 (CNAS-CL01:2018). Through systematic efforts including proficiency testing, inter-laboratory comparisons, and strict internal audits, the team successfully passed an on-site assessment held on June 28–29. The scope of accreditation covers chemical composition analysis, mechanical properties testing, metallographic examination, salt spray testing, and other key areas related to aluminum alloys.

What CNAS Accreditation Represents

CNAS is China’s sole national authority for laboratory accreditation. CNAS accreditation, based on the internationally recognized ISO/IEC 17025 standard, ensures that laboratory results are authoritative, reliable, and mutually recognized across more than 60 economies worldwide. It serves as a "passport" to global market acceptance.

Strength in Technology, System, and Talent

The accreditation reflects the Center’s strong technical capabilities, supported by over 25 advanced testing and processing equipment units; a well-implemented management system; and a professional team composed largely of bachelor’s and master’s degree holders, including seasoned experts in aluminum material testing.

Enhancing Value and Global Reach

For YONZ, the accreditation reinforces the company’s commitment to quality and technological innovation, strengthening its competitive position in the green energy materials sector. For customers, it guarantees more authoritative test reports, which can facilitate product certification and market access—particularly in key overseas markets such as the U.S. and India.

Looking Ahead

The CNAS accreditation is a starting point for continuous improvement. The Testing Center will further expand its capabilities, follow evolving industry standards, increase R&D investment, and strive to become a leading testing laboratory in the Yangtze River Delta region. By engaging in international cooperation and maintaining a customer-focused approach, the Center will support YONZ’s global strategy and contribute to the healthy development of the aluminum materials industry.
