CQI-9 Heat Treat System Assessment

Significance and Application of CQI-9 Heat Treatment System Assessment

The North American automotive association AIAG (Automotive Industry Action Group) is publisher of the CQI standards (Continuous Quality Improvement). CQI-9 Heat Treatment System Assessment is a self-assessment of the heat treatment system and must be carried out at least once a year.
This standard is an appendix to IATF 16949 under „customer-specific requirements“ and is valid for all automotive suppliers globally that have entered into a contractual agreement regarding purchasing, supply and quality throughout the supply chain.
As a long standing member of the AIAG, TopQM-Systems already specialized early on in the introduction, development and qualification of employees, as well as auditor training according to the rules of the AIAG for CQI-9 heat treatment processes in the European and global automotive supplier markets.
