The laboratory is accredited under the RBLE – Brazilian Network of Testing Laboratories and ONA – Organismo Nacional de Acreditación Paraguay.
WE have a specialized team of technicians and strive to continuously enhance their technical abilities in order to better meet the needs of our clients.
The lab also participates in the INMETRO’s GT – Working Group for Wire and Cables, developing activities that involve the study and application of technical standards as well as compiling RACs – Conformity Assessment Regulations.
The Wire and Cables Testing Laboratory – is accredited for all the mandatory Brazilian wire, cables and cord standards, as well as the telephone wire and cables involved in ANATEL certification.
The Wire and Cables Testing Laboratory was established in 2000 catering to almost all the testing demands for mandatory certification of Cables and Cords under to NBR 13249, for which there was no accredited laboratory in the country.
Since February 2006, LABELO has included new equipment in its Wire and Cables Laboratory, built to better meet the needs of clients, with modern state-of-the-art equipment and testing devices developed by LBELO itself.
