Founded in 1991, it was the first LABELO lab to receive Cgcre accreditation and has been in operation for more than 20 years. It was in this laboratory that the calibration process was developed for Doppler radar speed cameras used by Federal and State Highway Patrol departments all over the country. For several years, LABELO was the only site in the country where calibration of this equipment was possible with RBC accreditation. Subsequently, as a result of regulations compiled by the INMETRO Directorate of Legal Metrology, these calibrations were taken up by INMETRO itself and became known as Metrology Verification.

The laboratory came about in 2001 through the need to conduct tests on electromagnetic reactors for fluorescent tube lamps. In 2004, new directives also made it compulsory to test electronic reactors for fluorescent tube lamps and electromagnetic reactors for high pressure vapor lamps (sodium vapor and metallic vapor).

As well as the other standards involved in testing, we also obtained accreditation under Inmetro ordinances 454 and , which regulate the mandatory testing of Electromagnetic Reactors for Sodium-Vapor and Metallic-Vapor Lamps for electrical safety and performance requirements. We participate in GT-LUZ – the Inmetro working group for lamps – developing activities that involve the study and application of standards and and compiling RACs – Regulations for the Assessment of Conformities.
