The National Institute for Standards (NIS) is the measurement institute of the Arab Republic of Egypt and the custodian of traceable standards to the International System (SI) of units. NIS is the largest metrology body in the Middle East and Africa, and the sole representative of Egypt at the International Bureau of Weights and Measures (BIPM). NIS was establised in 1962. Since its establishment, NIS has developed and maintained the nation’s primary measurement standards and disseminated them to the end user with the highest possible accuracy. These primary standards underpin an infrastructure of traceability through Egypt and the world to ensure accuracy and consistency of measurements.
