YG Group Officially Recognized with CNAS Accredited Lab Status

YG Group Achieves CNAS Accreditation: Strengthening Global Trust in Adhesive Testing, Quality Assurance, and Material Innovation

YG Group has reached a major milestone in its pursuit of scientific excellence and global leadership in adhesive and new material technologies. The company’s Analysis & Testing Center has officially passed the rigorous assessment of the China National Accreditation Service for Conformity Assessment (CNAS) and has been awarded the CNAS Accredited Laboratory qualification.

This accreditation covers multiple core testing categories, including physical performance testing, chemical performance analysis, accelerated weathering, adhesive behavior evaluation, and many other critical pillars essential to the adhesive, tape, label, film, and specialty material industries.

Because CNAS operates under the ILAC MRA (International Laboratory Accreditation Cooperation – Mutual Recognition Arrangement), YG Group’s accredited laboratory reports now carry global mutual recognition, meaning testing data and conclusions are accepted in numerous countries and regions worldwide.

This achievement places YG Group among the industry’s highly respected international testing laboratories and marks a new era of global competitiveness for the company.

What CNAS Accreditation Means and Why It Matters

CNAS is China’s nationally authorized accreditation body, established under law to evaluate and accredit laboratories, inspection bodies, and certification organizations. Its assessment framework is aligned with the globally recognized standard ISO/IEC 17025:2017, which is the highest benchmark for laboratory competence, impartiality, and consistent operation.

For a laboratory to earn CNAS accreditation, it must meet stringent requirements in:

• Technical competence

• Testing methodology standardization

• Staff qualification and training

• Equipment calibration and traceability

• Quality management frameworks

• Record integrity and auditability

• Environmental and operational control

Only laboratories that demonstrate end-to-end compliance with these criteria are granted the CNAS mark—a quality seal that holds international credibility.

Why CNAS matters specifically for the adhesives and materials industry

In the adhesive industry, precision in testing is not optional—it is essential. Even minor discrepancies in coating thickness, adhesive formulation, polymer structure, or environmental exposure can significantly impact:

• Bonding strength
• Durability
• Temperature resistance
• Weather resistance
• Chemical compatibility
• Safety and reliability

CNAS accreditation confirms that YG Group’s testing data is scientifically robust, globally recognized, and reliable for customers in the automotive, packaging, label, decor, advertising, hardware, home & office, hot melt, and protection sectors.
