Electronic Certificate of Calibration

With effect from 11 May 2026, the Standards and Calibration Laboratory (SCL) will fully implement electronic calibration certificates, which will replace the existing paper based Certificates of Calibration. From that date onward, only electronic certificates will be issued, and paper certificates will no longer be provided. If a printed calibration certificate is required, please indicate this as a special remark on the Application for Calibration Service Form (ITC 28) at the time of submission.

Paper calibration certificates issued before 11 May 2026, as well as electronic calibration certificates issued on or after that date, shall remain valid and shall carry the same technical recognition.

For enquiries regarding the issuance of electronic calibration certificates or other matters, please contact the Standards and Calibration Laboratory at telephone (3543 5769), by fax at (3543 5889), or by email at (scl@itc.gov.hk).
