These play a vital role in training and certification of ndt personnel in member states. When fault is detected in any device, the device pulls the nfault line low, triggering sequential power down starting with the end device. The fau testing centers will now administer canvas computerbased makeup exams. It is assumed that a program can only be incorrect in a limited fashion specified by associating alternate expressions with program expressions. Diagnostic test services range from a single laboratory test to comprehensive laboratory services covering many pathogens for a suspected disease outbreak.
