Within the scope of the inter-laboratory comparison test (external quality control test) we offer as Z-Test, we also provide you with access to these programs in many different analysis areas, especially environmental, water and food analysis.
1. ISO 17043 conditions are followed for the management of comparison tests.
2. In applications to the organized comparison tests, the current ISO 17025 accreditation validity of the participants is questioned. The final registration of the participants to the tests is only possible if they are accredited according to the ISO 17025 standard. If there are not enough participants for test, laboratories can be accepted if they are in accreditation progress or they have min. 3 years experience in the relevant parameters. All participants are informed about this process.
3. Our quality policy in comparison tests has been prepared and approved by the senior management. According to our relevant quality policy; all participants, whenever they present their results, learn the assigned values of the comparison test they have participated in, in the results report and at the same time.
4. Information about the activities and calculations to be made within the scope of the cycle is provided to the laboratories with documents on our website or after the participation request, and all this information is also included in our result reports in detail.
