The accreditation of conformity assessment bodies (laboratories, inspection and certification bodies) is the legal mandate of the German Accreditation Body (DAkkS).
In the accreditation process, professional competence is assessed, confirmed and monitored in accordance with strict guidelines.
To ensure that proof of competence conducts surveillances at fixed intervals.
The DAkkS accreditation certifies that the accredited bodies fulfil their tasks competently, according to valid requirements.
The surveillance assessment /audit 2020 resulted from the necessity to convert to the new international standard within the framework of regular surveillance.
Compliance with the new standard makes it possible to determine laboratory results in a technically competent manner and ensure their international acceptance.
The result of the successful audit was the confirmation of the existing DAkkS accreditation and the competence as DAkkS-accredited testing laboratory in an annex to the accreditation certificate D-K-19573-01-00 according to DIN EN ISO/IEC 17025:2018 for :
