Changzhou, July 8, 2025 — Changzhou Eging Photovoltaic Technology Co., Ltd. ("Eging PV") announced today that its Technology Research and Development Center (a CNAS-accredited laboratory) successfully passed the periodic reassessment by the China National Accreditation Service for Conformity Assessment (CNAS) on July 6, 2025. This achievement reaffirms the Center's continued compliance with international standards in management systems, technical capabilities, and testing proficiency. Its test results maintain global mutual recognition status, providing robust authoritative technical support for Eging PV's expansion into overseas markets.

The reassessment was conducted by an expert panel appointed by CNAS, who performed a comprehensive on-site audit of the R&D Center laboratory. The review covered critical areas including management system operations, inter-laboratory comparisons, equipment calibration, external proficiency testing, personnel competency assessment, testing procedure standardization, and quality control. The panel highly commended the laboratory for its standardized management, document control, custom test development capabilities, technological innovation level, and the accuracy of its testing data. Ultimately, the experts unanimously confirmed that the laboratory continues to meet the requirements of CNAS-CL01 Accreditation Criteria for the Competence of Testing and Calibration Laboratories (equivalent to ISO/IEC 17025), approving the continuation of its accreditation.

As the core technological engine of Eging PV, the R&D Center consistently focuses on the forefront of photovoltaic technology, continuously enhancing its testing capabilities. Its core competencies include:

· Module IV Testing: Equipped with Class 3A+ simulators and achieving "Satisfactory" results in the 2024 Key Optoelectronic Performance of PV Modules proficiency testing.

· Module Reliability Testing: Comprehensive coverage of core international standards including IEC 61215, IEC 61730, and IEC 61701.

· New Material Qualification Testing: Ensuring the performance and reliability of new materials.

· Order Product Sampling Inspection: Guaranteeing the stable and reliable quality of finished products.

This successful reassessment significantly elevates Eging PV's technical authority within the global photovoltaic industry chain and provides solid qualification assurance for its products in international markets.
