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 great tool for those searching for an accredited testing or calibration laboratory.
Please refer to the list below for directories of ISO/IEC 17025:2005 accredited laboratories 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@example.com.
