The National Institute of Metrology (Thailand) has reaffirmed its leadership in the international metrology community through its prominent role in the 6th International DCC Conference. Held under the theme “From Good Practice to Standardization: DCC for a Reliable Future,” the conference took place as an online event from February 24–26, 2026.
Dr. Jariya Buajarern, Expert Metrologist at NIMT, was honored to serve as the Chair of the International Programme Committee. She delivered the opening welcome address alongside distinguished global metrology leaders, including Dr. Frank Härtig, Vice President of PTB (Germany), and Dr. Stephan Schlamminger, Physicist from NIST (USA). The conference successfully brought together over 600 registered participants from 82 countries to shape the future of digital quality infrastructure.
Representing NIMT’s technical advancements, a research paper titled “Measurement Capability Modeling and SI-Compliant Unit Representation for Digital Calibration Certificates” was presented by Miss Praiya Thongluang, researcher of the digital transformation center of NIMT. This work details the enhancement of NIMT’s DCC Web Portal, which now supports advanced measurement capability modeling. A significant contribution of this architecture is the development of a CMC Database and a Scope of Accreditation Database. These databases provide a formal, machine-interpretable digital representation of laboratory capabilities, ensuring that generated DCCs are strictly aligned with authorized ranges and institutional trust levels.
Furthermore, NIMT’s framework ensures that unit representation adheres to the SI Digital Framework published by the BIPM. By treating SI prefixes, base units, and exponents as separate semantic components, the system achieves unambiguous and standardized unit encoding. This transition moves metrology from being document-centric to capability-driven, allowing calibration results to be fully machine-readable and interoperable across global data spaces.
The shift from traditional PDF certificates to Digital Calibration Certificates (DCC) is a critical enabler for Industry 4.0. By following FAIR principles (Findable, Accessible, Interoperable, Reusable), DCCs eliminate manual transcription errors, reduce processing times, and facilitate the automated exchange of trustworthy metrological data.
