YIZUMI’s Metrology and Testing Center Achieves CNAS Accreditation for Calibration

YIZUMI’s Metrology and Testing Center has achieved CNAS accreditation in both testing and calibration, marking a significant advancement in its quality assurance capabilities. Following its CNAS accreditation in the testing field in 2024 (Accreditation No. L20604), the center successfully passed the rigorous assessment for calibration in May 2026 and was officially granted accreditation by the China National Accreditation Service for Conformity Assessment (CNAS). With this achievement, YIZUMI has become the company in the compression molding industry to receive CNAS accreditation in both testing and calibration.

01.「From Testing to Calibration」

Dual CNAS Accreditations Achieved in Two Years

In 2024, the Metrology and Testing Center successfully passed its first CNAS assessment, enabling it to issue accredited reports and establish a more reliable quality foundation. The center adheres to a quality policy of “scientific, impartial, accurate, and efficient,” and continues to strengthen its testing foundation while accumulating extensive experience in quality management.

Building on this foundation, the center launched its calibration accreditation expansion in 2025. After more than a year of systematic preparation, it successfully passed the CNAS on-site assessment in May 2026. YIZUMI officially obtained accreditation for calibration.

02.「Testing + Calibration Integration」

For a Complete Quality System

The dual accreditation enables the center to strengthen both testing and calibration capabilities. Testing ensures traceability and accuracy from raw materials to finished products, while calibration guarantees the reliability of measurement equipment and stable process control. Together, they form a closed-loop quality system that enhances production stability and supports consistent product quality.
