Our quality management is a central part to our company philosophy, assuring that our customers can rely on the first-class quality of our work. For our employees, this means to be constantly checking the quality of their work and always focusing on improving the quality. In addition, the tests and the analytical precision are constantly improved, to achieve the high level of result reliability that our customers can expect from us. Since 2004, CTL® has been accredited according to DIN EN ISO/IEC 17025. This is a special standard for assuring the quality of testing and calibration laboratories.

With the accreditation, we undertake to guarantee you safety and to test and evaluate your samples independently and objectively. We use standard-compliant, accredited test procedures. Large parts of our chemical-analytical tests on textiles, toys, leather and tattooing materials are classified in a flexible accreditation range. This means that for this accreditation area, based on our outstanding competence and many years of experience, we are authorised by the DAkkS (i.e. the national accreditation body of the Federal Republic of Germany) to adapt test procedures to your requirements, while adhering to strict quality criteria.
