The Ministry of Industry, Science, Technology, and Innovation has prioritized competent management and leadership in the field of metrology, emphasizing accuracy, fairness, and reliability. This focus includes recognizing the capabilities of international calibration laboratories. To align with regional and international metrology institutions, the National Metrology Center (NMC) has strengthened its capacity to become both a full and observer member of international and regional organizations, while also fostering good cooperation with development partners from countries such as NIM-China, PTB-Germany, and KATE-Korea. Metrology is a key sector that has served as a significant driving force for economic development in both developing and developed countries.

According to the Royal Kram NS/RKAM/0320/009, dated March 26, 2020, which promulgates the Law on the Establishment of the Ministry of Industry, Science, Technology, and Innovation under the supervision of the Royal Government of the Kingdom of Cambodia, the Ministry has the authority to direct and manage science, technology, industry, and innovation, including the handicraft and water sectors of the Kingdom of Cambodia. Additionally, Article 5, Chapter 2 of the Law on Metrology, promulgated by Royal Kram No. NS/RKAM/0809/016, dated August 11, 2009, mandates that the National Metrology Center (NMC) manage all activities and services related to metrology, including scientific, industrial, and legal metrology, in accordance with national metrology policy. Under the supervision of the Ministry in charge of industry, the NMC holds the same status as a General Department and possesses its own seal.

Based on Article 29, Chapter 11 of Sub-Decree No. 48, dated April 6, 2020, regarding the Organization and Functioning of the Ministry of Industry, Science, Technology, and Innovation, the National Metrology Center (NMC) holds the same level as a General Department and is responsible for the following tasks:

The field of metrology plays a vital role in our daily lives, contributing to social well-being and modernization by supporting trade, technical regulations, production standards, and consumer protection. Metrology impacts nearly every aspect of human life. It ensures fair, equitable, and transparent trade, protecting the interests of both suppliers and consumers of products, goods, and services. Metrology builds trust in the use of precise instruments across commercial activities and other sectors, including health, safety, and environmental protection. Furthermore, metrology contributes to the sustainability and growth of the national economy, playing a key role in enhancing living standards and advancing poverty alleviation efforts.

The National Metrology Center, through its Scientific Metrology Department's calibration laboratory, is preparing for accreditation and aims to achieve ISO/IEC 17025:2017 certification by 2025. This accreditation will cover areas such as mass, pressure, capacity, temperature, and volume in collaboration with Cambodia's General Department of Accreditation, ensuring compliance with national standards and laboratory competency criteria under the Cambodian Standards Law. 

The National Metrology Center has developed a strategic plan for the advancement of metrology in Cambodia for 2023-2027, with input from relevant institutions and development partners. This strategic plan will guide national metrology operators and stakeholders in consistently and effectively supporting metrology work. The plan is built around five strategic pillars, each outlining specific goals to be achieved by 2027. These are:

1. Promote metrology services that support the market
2. Strengthen the implementation of the Law on Metrology
3. Harmonize and integrate metrology
4. Raise stakeholder awareness about metrology
5. Develop capacity and strengthen general support functions

The National Metrology Center operates with a clear vision, mission, and goals:

• Vision: The metrology sector in Cambodia is well-developed, improving the quality of production and ensuring fair and competitive trade, thereby contributing to national economic growth.
• Mission: To provide comprehensive metrology services to trade, industry, and other sectors, in line with internationally recognized standards, to ensure measurement accuracy and promote health, safety, and environmental protection.
• Goals: To achieve the vision and mission, five key goals have been identified:
1. Promote and expand metrology services that support the market.
2. Strengthen the enforcement of the Law on Metrology.
3. Harmonize and integrate metrological efforts.
4. Increase stakeholder awareness of metrology.
5. Develop capacity and enhance general support functions.

The National Metrology Center plays a vital role in Cambodia, with the importance of metrology increasingly recognized due to continuous development driven by government policies and support from various stakeholders.

Currently, metrology services are being provided and utilized by industries and trade sectors. The primary services include calibration (e.g., weight, volume, mass, length) and verification services aimed at strengthening law enforcement and ensuring compliance with metrological regulations. Users of these services include individuals and organizations that use measurement tools for production purposes, such as private and public companies, as well as laboratories. Many companies utilize these services to meet the requirements for ISO certification, which is often mandated by their buyers. Users of metrology services appreciate that local services are easy to communicate with, affordable, and of acceptable quality.

According to Inter-Ministerial Proclamation No. 836 MEF. PrK.A.T., dated November 14, 2023, regarding the provision of public services by the Ministry of Industry, Science, Technology, and Innovation, the National Metrology Center provides various metrological public services, including:
