Standardization in the United States

Standardization in Mexico extends back over a considerable number of years. In 1926 the Secretariat of Industry and Commerce prepared a National Electrical Code which has been influential in guiding Mexican progress ever since. In recent years, standardization in a broad field has been an important activity of the Ministry of National Economy which in 1943 established the Direction General de Normas, (DGN). Under the initiation of DGN and with the co-operation of Mexican industry and professional organizations more than 100 standards have been adopted to guide Mexican federal government purchases, covering a wide range of commodities.
