Quality Management
Our quality management system
The Tentamus chelab quality management system describes the framework within which optimum service has been offered to customers for over 45 years now. With the first accreditation in May 1999, the quality of the services and documentation was confirmed for the first time. To this day, the laboratory is accredited in accordance with the current DIN EN ISO/IEC 17025. The accreditation indicates that tests are carried out competently, objectively and independently.
Many of the methods we use are accredited. Where possible, we try to work according to standards or procedures similar to norms and standards in order to offer our customers the highest possible level of reliability with recognized methods. In-house methods have been validated to be included in the scope of accreditation.
Our accredited methods are shown in the current accreditation certificate annex and in our list of test methods within the scope of accreditation, which can be downloaded in the download area.
The annex to the certificate reflects the scope of accreditation at the time of issue, the test methods listed are examples and the list can be extended by the laboratory depending on the flexibilization status of the individual test areas. The list of test procedures within the scope of accreditation will be updated by us as soon as further procedures are included in the flexible scope of accreditation.
The high analytical standard is regularly ensured through the measurement of certified reference materials, participation in interlaboratory comparisons and quality assurance measures in everyday laboratory work.
Internal audits by the quality manager and external audits by the DAkkS also support the quality of the quality management system and its suitability to achieve the objectives described in the quality policy and allow continuous improvements to take place.
Accreditation by the DAkkS in accordance with the current DIN EN ISO/IEC 17025 is therefore a confirmation of competence, quality and trustworthiness.
