Question Z540.3 and Guardbanding: Who audits compliance to Z540.3

I know Z540.3 replaced Z540.1, and it addresses not only measurement uncertainty but also probability of false accept/reject (also known as guardbanding). This is not something normally audited by A2LA, so who audits compliance to Z540.3? Is there a checklist somewhere?

Check the NIST site I don't qualify because not all my standards are traceable to NIST but are traceable to the SI this pisses me off. I do all the right things but it still does not count yet.... BTW even Lockheed Martin GTL calibration services (F35 stealth manufacturer) and the USAF PSL are not Z540-3 I know because they are approved suppliers

The Laboratory Accreditation Bureau can assess labs to ANSI/NCSL Z540.3.

I went to the A2LA website and they do accredit labs to the Z540.3 standard from what I can tell

Yes, A2LA as well as L-A-B both perform Z540.3 accreditations.

Re: Z540.3 and Guardbanding: Who audits compliance to Z540.3

New Guy here.
I am QA in a Part 145 repair station. Recently during an external Customer audit the question came up "do we need to advance to the Z540-3 standard?". Is this strictly voluntary?

Currently our calibration procedures comply to the Z540.1. We only calibrate dial calipers, micrometers, and torque wrenches for use in-house by OUR mechanics only. We do not have a calibration lab per se. We send out all other calibrated tooling to labs that are compliant to the Z540-3 standard.

Since we calibrate our own tools only, are we required to comply to the Z540-3? If not, where can I get objective evidence of this to submit to the Auditors?

Thanks for any input !!
