In the past, infrared (IR) cameras were not accepted by NRTL's to be used in lieu of direct contact methods (i.e., thermocouple, fiber optics, etc.) for surface temperature testing (thermal analysis). This was primarily due to the inaccuracies of the IR technology and calibration difficulties. However, IR camera technology has improved considerably and there are units out there that have accuracies well within the limits defined by CTL Decision DSH251B which defines the limits to be: <100C, +/-2C; 100 to 500C, +/-3%; -35C to -50C +/-3C. Thus, my question is, has anyone had any success recently utilizing IR cameras for temperature testing as part of a NRTL evaluation? I'm interested in both positive & negative experiences. Include the product type, standard used, NRTL involved and any challenges experienced. Regards, Nick Momcilovic Product Compliance Lead Engineer GE Healthcare Magnetic Resonance -
