About 4TIERS
4TIERS GmbH specializes in proficiency tests (interlaboratory comparisons) in the field of environmental simulation. The company develops the specific test specimens and test procedures required to conduct proficiency tests for environmental simulation testing. In a proficiency test, identical samples are distributed to multiple laboratories, which test them independently; the results are evaluated and compared centrally. The aim is to assess the competence of the participating laboratories and to identify deviations in testing processes. The offering includes proficiency tests for cold testing (IEC 60068-2-1), vibration testing (IEC 60068-2-6/2-64), temperature change (IEC 60068-2-14), shock (IEC 60068-2-27), damp heat cyclic (IEC 60068-2-30) as well as electromagnetic compatibility (EMC). For testing laboratories, proficiency tests are an important tool for meeting accreditation requirements such as cofrac, UKAS, Accredia or DAkkS. Partner for the proficiency tests is the German Reference Office for Proficiency Testing and Reference Materials (DRRR), accredited by A2LA and DAkkS.
