What is EQA Test in ISO17025

EQA stands for “External Quality Assurance” and refers to the ISO 17025 requirements in clause 7.7 Ensuring the validity of results, for a laboratory to  monitor its performance by comparison with results of other laboratories. How a laboratory does this depends on the type of testing and the type of comparison that is available and appropriate. This can be participation in proficiency testing or other means, for example, is appropriate bi-lateral comparisons or use of certified reference material. I suggest you contact your accreditation body and obtain their rules for Proficiency Testing and other comparison programme requirements for ISO 17025 accredited facilities in your sector. See too the ILAC P9:06/2014 ILAC Policy for Participation in Proficiency Testing Activities (the policy for accreditation bodies on the use of proficiency testing activities in the accreditation process), available from https://ilac.org/publications-and-resources/ilac-policy-series/
