This paper presents the activities currently being performed at the Inmetro with a view to obtaining the international recognition of its quantum Hall system as the primary standard of electrical resistance in Brazil. To enable it, the Inmetro is making arrangements to take part in the ongoing key comparison BIPM.EM-K12, which is an on-site comparison of quantum Hall effect resistance standards. Besides, as a prerequisite for joining in this key comparison, Inmetro is participating in the ongoing key comparison BIPM.EM-K13.a&b.
