Need to find an ISO 17025 Accredited Laboratory?

Today, I answered a question on LinkedIn and thought it would be an excellent post to share on my blog. The post asked a question that I encounter quite often, “Does anyone know where I can find a list of metrology labs in the US?” Well, I took the answer that I had posted which is a list of directory searches for the ISO/IEC 17025 accreditation bodies in the United States that are members of the ILAC Mutual Recognition Arrangement or ILAC/MRA. Furthermore, I have included a link to the full ILAC member directory and the BIPM directory of National Metrology Institutes or NMIs. I hope the list provided is a great tool for those searching for an accredited testing or calibration laboratory.

Please refer to the list below for directories to find an ISO 17025 accredited laboratory in the United States.

If you are looking for more information, the ILAC website will identify signatories of the ILAC/MRA; but, it will not provide you with a list of laboratories.

If you are looking for National Metrology Institutes, check out the BIPM website.

If you find this list helpful and want to connect or if I have you have any additional information that you would like to share, please contact me at [email protected].
