State of the art polymer testing
Our laboratory's objective is to test polymer materials, packaging, and products to assist in determining their compliance with the circular economy
Laboratory methods
The laboratory is accredited in accordance with the standard LVS EN ISO/IEC 17025:2017 “General requirements for the competence of testing and calibration laboratories.”
Registration No. LATAK-T-687 with the Latvian National Accreditation Bureau.
The laboratory’s accreditation certificate for the testing scope is valid until 19 September 2029.
The organization of the laboratory’s work is based on the requirements of LVS EN ISO/IEC 17025:2017, as well as on the principles of the LEAN efficiency program (methods – 5S, Kaizen, and Asaichi).
The laboratory was established within the framework of the European Union project LIFE20 IPE/LV/000014 – LIFE Waste to Resources IP.
