Certification Body for Geosynthetics

The Certification Body for Geosynthetics of the Sächsisches Textilforschungsinstitut e.V. (STFI) was accredited by the German Accreditation Body GmbH (DAkkS) in spring 2013. The certificate also certifies compliance with the requirements of Article 43 of the Construction Products Regulation for a Certification Body for Factory Production Control.

The notification (designation) subsequently requested from the German Institute for Building Technology (DIBt) for the activity within the scope of the accreditation decision (conformity certification procedure 2+ for geosynthetics) was issued with a decision dated May 31, 2013.

The accreditation of the Certification Body for Geosynthetics (D-ZE-11239-02) has been converted to DIN EN ISO/IEC 17065 and is valid until January 30, 2023.

Since the STFI is already notified to the EU under number 0516 for the product area "Personal Protective Equipment", this designation has now been extended to the product area "Geosynthetics". The Certification Body for Geosynthetics (as notified body 0516) is continuing its work which began in 2001 in the STFI subsidiary, the Institute for Technical Textiles GmbH.
