Recently, the CZ laboratory, which already holds CNAS national laboratory accreditation, achieved another significant milestone by officially obtaining the DNV Witness Testing Lab qualification. A grand plaque-unveiling ceremony was held on November 22, 2025, at the site of an explosion-proof technology seminar. Mr. Huang Jianfeng, General Manager of CZ, and Mr. Li Xiang, Director of DNV, jointly presided over the ceremony. This event marks the full alignment of CZ's testing capabilities in the explosion-proof electrical field with authoritative international standards.

Authoritative Support for High-End Global Applications

As a leading domestic enterprise in the explosion-proof electrical sector, CZ has always regarded technological innovation and quality assurance as its core driving forces. Obtaining the DNV Witness Testing Lab qualification is not only an authoritative recognition of CZ's laboratory hardware facilities, technical team, and quality management system, but also provides critical technical support for the reliable application of CZ products in high-end fields such as:

• Ocean-going vessels
• Offshore engineering
• Petrochemical industries

DNV is a world-leading certification and risk management organization with high international credibility in the maritime and energy sectors. This deep cooperation will establish a more solid foundation for the superior quality and global application of CZ products.

Safeguarding Industrial Safety and Expanding "Blue Ocean" Markets

During the seminar, General Manager Huang Jianfeng stated, "This cooperation with DNV is a significant step for CZ toward broader markets. We will continue to increase investment in the laboratory and promote the R&D and application of explosion-proof technology to contribute to global industrial safety". Director Li Xiang also acknowledged CZ's technical strength and rigorous attitude in the explosion-proof field, expressing his expectation for both parties to jointly promote the improvement of industry standards and technological innovation.

Strengthening Explosion-proof Quality Control: A Foundation of Trust for Global Safety

Relying on its "dual accreditation" capability system, the CZ laboratory utilizes nationally and internationally recognized technical capabilities to support internal R&D and quality verification, while providing high-standard testing services to customers. Every credible test result serves as a "foundation of trust" for product quality.

Moving forward, CZ will continue to uphold the philosophy of "Professional, Precise, and Innovative," injecting continuous momentum into the high-quality development of the explosion-proof electrical industry. CZ remains dedicated to its corporate mission—"providing safety protection for human life and property"—to safeguard industrial safety, help customers improve quality and efficiency, and jointly explore "blue ocean" markets.
