Abstract

During the 1980´s, before the industrial globalization took place, some recommended practices or standards were used to provide the calibration services for inspection, measurement and testing equipment (IM&TE) in America. Before the ISO Standards were used to provide quality services or to be ISO accredited, the calibration laboratories were using the MIL-STD-45662A. While the ISO standards became the most applicable references for quality systems certification and for the accreditation of the calibration laboratories the ISO/IEC-17025 became the standard that should be met for the accreditation. Since the beginning of the calibration services, the calibration certificates contained information about the status of the instrument, depending of its type and the method used to calibrate the instrument, also some other requirements were included in the certificates, like the uncertainty and the evidence of the proficiency tests that the laboratory had to provide. With the technological advancement in electronics, the instruments became more sophisticated and accurate. The use of computers and dedicated software for calibration developed new calibration methods. Industry 4.0 includes a wide variety of sensors to monitor different parameters along the process or to measure quality specifications, most of those sensors are electronically integrated to the process control. Metrology 4.0 is giving a new way of calibration services applying the AI and IoT.
