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.

The new CQI-9 4th Edition Heat Treat System Assessment was released in June 2020.

The new CQI-9 standard can be purchased directly from AIAG.

You have the option of setting the standard as

  • E-Document including assessment or as
  • Hard copy/print version downloadable assessment.

We are licensed trainingpartner of the AIAG in Europe.
