The Laser Trackers owned by na Laser Trackers are also regularly tested in accredited laboratories. Certification is based on the standard from the ASME system with the number B89.4.19. This is a standardized method for calibrating laser trackers using NIST standards. The standard was officially released by the American Society of Mechanical Engineers in December 2006, several years after the FARO Laser Tracker was developed and began production.
