March 30, 2026 – The Analysis Center of Hunan Hunan Boyun-Dongfang Powder Metallurgy Co., Ltd.（the abbreviation is PM） officially obtained the Laboratory Accreditation Certificate issued by the China National Accreditation Service for Conformity Assessment (CNAS). This marks that PM’s testing capabilities and quality management system have reached national and even international authoritative standards.

Previously, the center had successfully passed the CNAS on-site assessment in December 2025, receiving high praise from the assessment team for its professional competence of testing personnel and laboratory management level. Following this accreditation, the testing reports issued by the company will carry international credibility and be readily accepted across global supply chains.

CNAS is a national accreditation body approved and authorized by the Certification and Accreditation Administration of the People’s Republic of China (CNCA), and is one of the most authoritative laboratory accreditation institutions in China.

Testing reports issued by CNAS-accredited laboratories can be mutually recognized in approximately 100 member economies under the ILAC-MRA (International Laboratory Accreditation Cooperation Mutual Recognition Arrangement) and IAF-MLA (International Accreditation Forum Multilateral Recognition Arrangement), achieving “one test, accepted globally.” If a report carries both the CNAS and ILAC-MRA international mutual recognition marks, it can be directly used in all signatory member economies, eliminating the need for repeated testing and significantly saving time and costs. For customers, this can be summarized as: time-saving, cost-saving, and worry-free, helping products smoothly “clear customs” for the global market.

Specific Scope of Accreditation：
Coercivity, Cobalt Magnetism, Rockwell Hardness (HRA), Vickers Hardness (HV30), WC Grain Size, Porosity and Free Carbon, Microstructure, Transverse Rupture Strength, Density, etc.

Core Equipments:
The center is equipped with high-precision core equipment supporting the above testing capabilities, including:

Magnetic Testing: Vibrating Sample Magnetometer (VSM)

Hardness Testing: Rockwell Hardness Tester, Vickers Hardness Tester

Microscopic Analysis: Scanning Electron Microscope (SEM), Metallurgical Microscope

Mechanical Properties: Servo Universal Testing Machine

Density and Composition Analysis: High-Precision Electronic Balance

For PM’s customers, this certificate represents not only an honor but also tangible value:

· Global Mutual Recognition of Testing Reports
    Testing reports accredited by CNAS can be mutually recognized in approximately 100 ILAC-MRA member economies worldwide, eliminating the need for duplicate testing. This significantly reduces customers’ time and financial costs, facilitating the rapid entry of products into the international market.

· Enhanced Quality Assurance
    CNAS accreditation is an internationally recognized “touchstone” of quality. It demonstrates that PM possesses stable and reliable product quality control capabilities, ensuring that every batch of products withstands rigorous inspection, giving customers greater confidence.

· Key Credential for High-End Supply Chains
    This accreditation is a critical qualification for entering the supply chains of leading companies in high-end manufacturing sectors such as aerospace and new energy vehicles. It provides stronger support for PM to expand into high-end markets.

The acquisition of this CNAS laboratory accreditation marks another significant milestone in PM’s quality control and technical capabilities. In the future, we will continue to delve deeper into the field of powder metallurgy, adhering to more stringent standards and leveraging more professional testing capabilities to provide global customers with even more reliable products and services, allowing trust to transcend borders and quality to win the future.
