Software verification and validation Software documentation consistent with moderate level of concern is submitted in this 510(k). System validation testing presented in this 510(k) demonstrates that all software requirement specifications are met and all software hazards have been mitiqated to acceptable risk levels # 8. Clinical Accuracy Validation Clinical accuracy validation testing was conducted according to ASTM E1965-98(Reapproved 2016). The clinical accuracy validation test report included temperature readings of 150 subjects, of which 50 subjects were infants, 50 subjects were children and the rest of the 50 subjects were adults (NOTE: Infants---newborn to one year; Children--greater than one to five years; Adults---greater than five years old.). The clinical accuracy validation test report demonstrates that the subject devices met the requirements for {8}------------------------------------------------ clinical bias and clinical repeatability per ASTM E1965-98(Reapproved 2016). # 9. Conclusion The Infrared Thermometer (Model HT-101, HT-102, HT-103, HT-104) is substantially equivalent to the predicate device (K191570). This conclusion is based upon comparison of intended use, technological characteristics and applicable safety standards. Any differences in the technological characteristics does not raise any new issues or concerns of safety or effectiveness.
