Electrical and electronic products that meet Brazilian requirements and that are certified by an INMETRO accredited organization must carry the mandatory INMETRO mark along with the mark of the certification organization, such as UCIEE (União Certificadora para o Controle da Conformidade de Produtos, Processos ou Serviços).

In this occasion, the INMETRO substitutes the National Institute of Weights and Measurements (INPM), significantly extending its range of performance for the Brazilian society.

Some of the main attributions of INMETRO are: During the first Empire, several attempts had been made aiming to the standardization of measurement units used in Brazil, but only in 26 of June 1862, emperor Dom Pedro II promulgated the Imperial Law nº 1157 and with it officialized, in all the domestic territory, the French decimal metric system.

With the following century industrial growth, it became necessary to create more efficient instruments of control in the country, so as to stimulate and to protect producers and consumers.

In 1973, INMETRO was created, in complementation to the CIP - Inter-ministerial Commission of Prices, including in its ample institucionalthe scope, the objective to strengthen national companies, increasing its profits by means of the protection to consumer rights and improvement of the quality of available products.
