Friday 7/2/2021 National Metrology Center of Iran
The first Measurement Law in Iran was ratified by the parliament on May 31, 1925 and the Metric System was adopted as the official measuring system in the country. With regard to the statute and the Law on the establishment of the the Institute of Standards and Industrial Research of Iran (ISIRI) in 1960, the Metrology, Weights, and Measures Center of Iran was established in 1975 as an affiliated body to ISIRI through the technical assistance of UNIDO, UNDP, and UNESCO.
In 1975, Iran joined Meter Convention and its membership at International Bureau of Weights and Measures (BIPM) and at International Organization of Legal Metrology (OIML) was approved by the parliament in 1985.
With regard to the driving force of the national development and the need to accessing the cutting edge technologies of the industrial countries, the Metrology Center of ISIRI managed to develop the National Metrology Development Strategy using the latest scientific, academic, and industrial capabilities. The first and the second five years programs were set according to the Strategy Program.
