Re-certification Audit for ISO 9001, ISO 14001, and ISO 45001 – 2025
In accordance with the requirements of ISO 9001, ISO 14001, and ISO 45001 standards, certified organizations are subject to Surveillance Audits in the first and second years of the certification cycle, followed by a Re-certification Assessment in the third year. This assessment must be completed prior to the expiration of the certificates to ensure continued certification.
On January 20–22, 2025, Don Muang Tollway Public Company Limited underwent the Re-certification Assessment for ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System), and ISO 45001 (Occupational Health and Safety Management System).
The audit was conducted by SGS (Thailand) Limited, serving as the Certification Body (CB). The assessment took place at the Head Office Building and Din Daeng Toll Plaza, where auditors performed sampling reviews of operational processes and documented evidence across various departments.
The audit results confirmed full compliance with the applicable standards, with no non-conformities identified. As a result, Don Muang Tollway Public Company Limited has successfully achieved re-certification for all three international management system standards, reaffirming the Company’s commitment to quality, environmental responsibility, and occupational health and safety excellence.
