ISO TS 16949 quality management standard in automotive industry (the new version of this standard is no longer ISO and is IATF16949)

The ISO/TS 16949 standard is a widely used standard in the automotive industry, and it can be said that in Iran, all companies that somehow work with a car manufacturer are required to comply with the requirements of this standard.
This standard is approved by all Iranian automobile manufacturers as well as international automobile manufacturers, and even the corporate requirements of Iranian automobile manufacturers such as Saipa are compiled based on the ISO/TS 16949 standard.
The ISO/TS 16949 standard can be considered the 9001 standard along with engineering and specialized requirements and techniques that can be very useful in the automotive industry.
Many of the requirements of this standard are heavy and specialized and the reason for this is because of the sensitivity of the automobile industry.
