AS9100 Rev. D 8.5.1 has a lot more to control of service than measurement.
Such as:
the availability of documented information
the appointment of competent persons
the implementation of actions to prevent human error;
the establishment of criteria for workmanship
the accountability for all products
the control and monitoring of identified critical items, including key characteristics, in accordance with established processes;
the provision for the prevention, detection, and removal of foreign objects;
Is AS9120 that different?
