The National Institute of Metrology (Thailand) (NIMT) is honored to welcome Mr. Taichi Yamazaki, Senior Researcher of the Organic Standards Group, Research Institute for Material and Chemical Measurement, National Metrology Institute of Japan (NMIJ), who is serving as a technical expert at NIMT from 3–13 February 2026.

Mr. Yamazaki was invited as a specialist in quantitative Nuclear Magnetic Resonance (qNMR) to provide technical consultation on the evaluation of organic compound purity using qNMR techniques. As a primary measurement method in chemical metrology, qNMR enables the direct determination of purity and content without the need for compound-specific reference standards, while requiring only small sample quantities.

His visit is expected to strengthen the technical capabilities of NIMT metrologists, support the development of new measurement services, and enhance the production of certified reference materials for high-purity substances — including important herbal compounds and controlled substances. This collaboration will contribute to reducing Thailand’s dependence on costly imported reference materials.

NIMT sincerely appreciates Mr. Yamazaki’s valuable expertise and looks forward to continued cooperation with NMIJ in advancing chemical metrology.

The National Institute of Metrology (Thailand) (NIMT) further strengthened international cooperation in metrology by conducting training in Acoustics and Vibration for the Uzbek National Institute of Metrology (UzNIM) during 26–30 January 2026 at UzNIM, Republic of Uzbekistan.

In the field of Acoustics, Ms. Panisara Kongthavorn delivered an intensive technical training program covering the calibration of sound level meters and sound calibrators, microphone calibration, and the evaluation of anechoic chambers. The training emphasized both acoustic and electrical characteristics, with detailed reviews of UzNIM’s existing calibration procedures, discussions on measurement uncertainty budgets, and alignment with international standards. Particular attention was given to free-field microphone sensitivity calibration using comparison methods, as well as the assessment and measurement systems of UzNIM’s anechoic chamber.

Concurrently, Mr. Pairoj Rattanangkul conducted Vibration Metrology Training, focusing on the transfer of vibration magnitude values from primary to secondary standards. The program addressed primary vibration calibration using laser vibrometers, secondary vibration calibration in accordance with ISO 16063-21, calibration of conditioning amplifiers, and vibration exciter calibration following ISO 16063-44. Comprehensive sessions on uncertainty evaluation, calibration reporting, and traceability statements were also provided, ensuring that participants could confidently apply the methodologies within their laboratories.

This training activity was implemented under the Physikalisch-Technische Bundesanstalt (PTB) project “Supporting the Reform of the National Quality Infrastructure in Uzbekistan”, which aims to enhance Uzbekistan’s national measurement capabilities in line with international best practices.

The successful completion of the Acoustics and Vibration metrology training represents a significant step in advancing UzNIM’s technical competence and laboratory capabilities. It also reaffirms the strong collaborative partnership among NIMT, PTB, and UzNIM, laying a solid foundation for continued cooperation and future joint initiatives in the field of metrology.

Dr. Jariya Buajarern, Metrology Expert, and Dr. Sivinee Sawatdiaree, RDI Manager, from NIMT, served as advisors for an advisory programme conducted at the Uzbek National Institute of Metrology (UzNIM) during 19–23 January 2026. The programme focused on practical examples drawn from NIMT’s institutional experience in management, policy formulation, and quality systems, with the aim of strengthening strategic capacity and long-term sustainability of UzNIM.

The five-day advisory programme covered a wide range of interconnected topics, including strategic dialogue on the transition from maintaining CMCs to long-term NMI development, integration of management systems, digital transformation of quality and operational processes, technical sustainability, emerging fields such as quantum metrology, and the role of research, development and innovation (RDI) in national metrology institutes. Interactive sessions, peer exchanges, laboratory visits, and practical demonstrations were used to facilitate in-depth discussion and mutual learning between NIMT and UzNIM experts.

The programme also included an institutional overview of UzNIM, highlighting its role as the national metrology institute of Uzbekistan and its active engagement with international metrology networks. Based on discussions and observations, NIMT provided strategic recommendations covering R&D roadmapping, quantum and digital metrology as future infrastructure, digital transformation as a management decision-support tool, and the evolution of quality management systems from a compliance-based approach to a strategic instrument for organizational development.

In addition, potential areas for future cooperation between UzNIM and NIMT were identified, including joint strategic workshops, exchange of experts and early-career researchers, pilot projects in digital and quantum metrology, and co-development of management and digital tools. The advisory programme concluded with a synthesis of key takeaways and a discussion on next steps and a medium- to long-term collaboration roadmap.

This activity was conducted under the PTB project “Supporting the Reform of the National Quality Infrastructure in Uzbekistan,” implemented by the Physikalisch-Technische Bundesanstalt (PTB), Germany. The advisory programme contributed to strengthening institutional capacity, enhancing the strategic use of management and quality systems, and promoting sustainable, future-oriented development of UzNIM, while reaffirming NIMT’s commitment to international cooperation and the sharing of institutional expertise.

Dr. Nunapus Laitip, an expert from NIMT, successfully completed a final expert consultancy mission to Indonesia on 22–23 January 2026, under the framework of technical cooperation with the Physikalisch-Technische Bundesanstalt (PTB).

The mission was conducted as part of the PTB cooperation project “Strengthening Quality Infrastructure Services for Environmental and Climate Monitoring, Indonesia.” The consultancy aimed to support national partners, particularly the National Measurement Standard – National Standardization Agency of Indonesia (SNSU-BSN), in the development and finalization of a suitable proficiency testing (PT) scheme for wastewater or surface water analysis, in collaboration with up to four regional environmental testing laboratories.

Building on the outcomes of earlier expert consultancies, this final mission focused on providing targeted technical support to Pusarpedal, an Indonesian environmental laboratory, to finalize and operationalize a new PT scheme within the project context. During the mission, Dr. Nunapus provided expert technical advice, reviewed technical arrangements, and offered practical recommendations to enhance the robustness, reliability, and international alignment of the PT scheme.
