Through the application of national and international standards, government, procurers and consumers can have confidence in the calibration and test results, inspection reports and certifications provided.” 
The Quality Infrastructure is organised at the national level. Therefore, we speak of a National Quality System (NQS) or National Quality Infrastructure (NQI).

Each of these institutions requires a legal framework because they act in the public interest. In some cases, the Quality Infrastructure institutions even assume sovereign tasks.

INetQI defined Quality Infrastructure as follows:
