Quality assurance system and testing
The factory production control and external monitoring together form the quality assurance system. There are clear requirements for the tests and test frequencies to be carried out as part of the quality monitoring of incinerator bottom ash. The specifications differ according to the planned use of the material.
The proof of suitability, as well as the tests of regular external monitoring, may only be carried out by recognised testing bodies. These test centres are recognised by the highest road construction authority of the respective federal state or by a road construction authority designated by the latter as competent.
