To build confidence in its services, TTS has the necessary accreditations to attest to its technical skills. TTS laboratories are accredited ISO / IEC 17025: 2017 by TUNAC (Tunisian Accreditation Council) which is an internationally recognized Tunisian public body, and the only one authorized to accredit testing and calibration laboratories in Tunisia.
Since 2008, TUNAC signed mutual recognition agreements with ILAC (International Laboratory Accreditation Cooperation) and EA (European Cooperation for Accreditation) for the accreditation of analysis, testing and calibration laboratories.
