ISO-17025 accredited TEST lab performing internal calibrations (Yes: Here is how)

This is kind of an extension of a previous thread:
https://elsmar.c*m/elsmarqualityforum/threads/internal-calibrations-part-of-an-iso-17025-accredited-testing-laboratory-automotive.78443/

The question arose: Does a 17025 accredited TEST lab need an additional CALIBRATION accreditation to calibrate its own equipment being used internally?

The answer from the ABs is: No.
The long answer from the ABs is: No, but you better abide by all various requirements laid out in 17025 for calibration labs.

I thought I would catalog the process as we are able to complete it. So far, I have talked with two ABs, and we have selected one with which to pursue accreditation. I won't be using their names, but they are the usual suspects, and were largely comparable in approach and cost. We are targeting external audits by end of year, so I will update this thread as that process moves forward.

As of June 2021:
* The AB is aware that we want to do our own calibrations. This does NOT affect our scope, but may affect our choice of assessor, as they need competency to evaluate our competency :)
* Right now, this is constrained to environmental chamber transducers (Temperature, Humidity, Pressure), with calibrations being conducted with externally accredited calibrated 'masters', such as calibration-grade humidity sensors, PRTs, etc.
* We have procedures for uncertainty, calibration records-keeping, and calibration traceability (i.e. pick your NMI that is party to the right MRA, etc.), and the other few requirements in the standard.
* We will be training over the next couple months, first by 'calibrating' chambers that are currently in accredited calibration, and ensuring we are consistent with those accredited calibrations. This includes practicing records-keeping, etc.
* I have yet to decide to what degree we do proficiency studies with an external provider, or if proficiency against traceable 'masters' and physical constants (i.e. boiling water, ice bath) is adequate for the relatively relaxed uncertainties we need for this application.

Anyway, that is the story so far. More to come.

The things you have learned from your AB are consistent with our previous discussions.
It is nice to get confirmation from the AB as to what they will be expecting, isn't it?

I like your approach and the details you provided. There is some error you can pick up from boiling water and ice bath. If you're doing near room temperature measurements, what about buying a high precision (but relatively inexpensive) thermistor and use that to verify the probes?

Brad, we have some 3 and 4 wire RTDs and a huge stack of thermistors around for random measurement needs. Unfortunately, our temperature ranges are -70C to 200C right now, and possibly up to 650C. Do you mean setting aside thermistors/RTDs or other gauges as an in-house reference to verify or study against our traceable 'masters'? I like that if it can take the place of external competency studies, and serve as a 'check' for shipping damage.

Oh... I see. My fault. I didn't read your entire temperature range of -70C to 200C. What I was suggesting was using a calibrated thermistor (calibrated by an external source) to do verifications at room temperature as opposed to trying to utilize boiling water and ice baths.

In my past life we did calibrations of many things. but as i have grown older and with technology. I leave it to the experts
