"Westgard Rules" and Multirules

To promote the concepts of internal control, Controllab received authorization from James O. Westgard to translate articles authored by him on Multiple Rules. These rules employ a combination of decision criteria and/or control rules to determine whether an analytical run is ‘in control’ or ‘out of control.’ Widely recognized as the Westgard Multiple Rules QC Procedure, it is embraced as a global standard.

PRM 0009

Certified Reference Material Producer

Accredited by Coordenação-Geral de Acreditação do Inmetro

Controllab has been accredited as a Certified Reference Material (CRM) Producer since 2016 by Cgcre, under number PMR 0009. The conformity assessment is carried out in accordance with the requirements established in ABNT NBR ISO 17034 and Inmetro standards, ensuring competence for the production of CRMs, as defined in the Scope of Accreditation.

This accreditation attests to Controllab’s technical competence in producing CRMs according to international requirements and enables it to be recognized in other countries, under mutual recognition agreements, thereby reducing technical barriers between Brazil and other countries across continents.

CAL 0214

Calibration Laboratory

Accredited by Coordenação-Geral de Acreditação do Inmetro

In December 2002, the Calibration Laboratory was accredited by Cgcre. With this recognition, it became part of the Brazilian network of accredited laboratories, under number 214. Since then, it has been periodically evaluated for the maintenance and/or extension of its accreditation.

The Inmetro seal attests to Controllab’s technical competence, credibility, and operational capability for calibration services, in accordance with the requirements of ABNT NBR ISO/IEC 17025.
