CQI

The CQI (Continuous Quality Improvement) range of standards is issued by the North American Automobile Association AIAG.
The fourth edition of the CQI-9 (Special Process Heat Treat System Assessment and Calibration) guidelines was published in 2020.
As a result, new requirements for automotive and aerospace customers are placing demands on calibration service providers. These include meeting the requirements for certified calibration. Chapter 1.3 of the Guideline specifically addresses the requirements for calibration laboratories to comply with ISO 17025.
The Instruction further refers to calibrations of thermocouples and the requirement for traceability of calibrations. All thermocouples must be calibrated before use in the range in which they will be used, etc.
In this industry, extreme care is therefore needed when selecting and considering a calibration provider, as the provider must be accredited to SIST EN ISO 17025. In the case of an inadequate calibration provider (or one that does not fully comply with the requirements of CQI-9), the assessment or audit may order the shutdown of the customer’s production process.
The CQI-9 guidelines are dictated by the requirements of the AMS 2750 standard (aerospace and automotive).
The ELPRO Calibration Laboratory will provide you with an accredited temperature calibration in accordance with CQI-9 guidelines.
