Managing Calibration Intervals1 Donald W. Wyatt President, Diversified Data Systems, Inc. Tucson, Arizona Howard T. Castrup, Ph.D. President, Integrated Sciences Group San Dimas, California Abstract This paper presents guidelines for implementing calibration interval management systems as components of computerized general calibration management systems. In addition to optimizing calibration interval management, following these guidelines can significantly contribute to improving compliance with MIL- STD 45662A and ISO-9000. 1. Introduction Calibration managers are faced with increasing pressures to minimize costs while improving compliance with Rev. A of MIL-STD-45662A, establishing compliance with ISO-9000, and improving the reliability of measurement and test equipment. By optimizing calibration intervals, unnecessary calibrations can be minimized, thereby reducing costs. Moreover, optimizing intervals will improve compliance with regulatory directives while ensuring maximal compliance with reliability targets. This paper presents guidelines for implementing calibration interval management systems, as components of computerized calibration management systems, which can significantly contribute to the achievement of these objectives. These guidelines include both background material for offering practical insights for implementing many of the concepts of NCSL RP-1 [1] and database structures and elements needed for optimizi
