Internal calibrations - Part of an ISO 17025 accredited testing laboratory (Automotive)

Please read the 2nd paragraph of the post you quoted.

I am currently starting to get my lab in shape for ISO 17025 accreditation as a test-only lab. We intend to calibrate our own environmental chambers (temperature and humidity) using traceable accredited calibration humidity and temperature probes.

This all leads in the direction of us doing the calibration work in-house.

What will an auditor want to see to accept this path?

I think that what threw me was this response of yours: You will need to notify your accreditation body that you perform calibrations on some of your equipment. That heads up will allow them to send an assessor familiar with calibration, and with the proper documentation to audit your calibration program.

If it was understood that the lab wasn't yet accredited, but was being prepared for accreditation, why would there be a need to specify an auditor familiar with calibration? Aren't all 17025 assessors familiar with calibration?

That is the specific reason why I mentioned that. They have specialists for all the disciplines, and if you are being accredited for concrete testing then they will not send out a calibration specialist. But if you are self calibrating your hardness testers... then you need to let the accreditation body know in advance.

Still makes no sense to me. Doesn't the equipment needed for concrete testing need to be calibrated? In this sense shouldn't all 17025 assessors understand requirements for calibration?

There is a huge difference from an assessment proving that a lab is using 17025 calibrated equipment and that the lab is operating as a 17025 accredited calibration facility.
When an assessor is auditing a test lab they typically are looking to see that the equipment used has 17025 accredited calibrations. A simple check of calibration documents is sufficient here.
This case is a test lab that is choosing to calibrate their own equipment. That requires a very different level of expertise on the part of the assessor. Basically this is going to be two separate assessments - one for testing and one for calibration. Maybe one assessor can handle both. My point is that the OP needs to contact his accrediting body to let them know his intention to self calibrate under 17025, so that the assessor(s) arriving there are prepared for both jobs.

Thank you both for the discussion. It gets to the heart of what I was wondering.

I envision testing lab accreditation only at this point. I will see what the AB says regarding conducting our own calibrations under a test-only scope, when we ask for quotes against our finalized scope.

it seems like more and more of the industry is going towards labs allowed to do their own verifications... i dont see any way to ensure impartiality in these cases... fabricators can now get product approval by submitting tests they conduct without a 3rd party present... and now test labs that don't need 3rd party calibrations... (they all have nist 17025 certs for the equipment used for verify/test/calibrate, but there is no one making sure the numbers are impartial)
