Re: Out of Tolerance Calibration Report

We utilize an out of tolerance report, which encompasses most of the items George listed earlier.

In short, it alerts the customer (internal customers) that their item failed calibration.

We also add a list of history for the instrument, going back three times (if we have the history for it).

We attach a copy of the calibration performed. We then work with the customer regarding any remedial action necessary, and have the customer sign the failure notice. This way... the calibration department is not responsible for the remedial action. Which would be difficult anyway, as we have little knowledge of all the processes which they are used.

Gee, George, in over 40 years of running operations, I never had it happen when I was a supplier and can only recall one instance where it occurred with one of our suppliers and we caught the N/C before we installed it in any of our products and we, in fact, were the ones who alerted our supplier there might be a problem with his instrumentation.

If a customer does a proper job of investigating suppliers prior to placing an order, it has been my experience that part of that investigation is looking for processes that PREVENT errors and nonconformances, not processes that DETECT them after they've occurred.
It's fairly common with what I've seen, to have calibration failures. When you are calibrating a bunch of process equipment, it's totally out of your control how they handle the equipment, what they purchased (many times), etc. Thus, there are going to be failures.

I do agree with your logic when it comes to standards within a lab. If you perform cross-verifications, practice redundancy, and keep close tabs on the cross-verification results, you can significantly limit any impact from an out of tolerance for your standards.

It still happens though. I have received a few from calibration vendors outlining exactly where it would out of tolerance, and how we might be affected.

Re: Out of Tolerance Calibration Report

A comment from the original Thread Posting Person would aid in this thread.
There has developed 2 seperate items of discussion, and which is the one requested is seemingly unclear.
#1. An O/T report, which is issued from a Calibration Serivice Organization, to a calibrated device, (DUT), owner as part of the calibration service under Z540 and etc. In this case the O/T report is a basic declaration of O/T. The Calibration Lab has no fault or liability in this case.
#2. A O/T report, which orgiginates from a facility, which is using a device, (DUT), and this facility either recieves an O/T type#1 or has discovered the O/T by inhouse verification(s). In this case there is process need to inform affected costomers, and more generally, potential effected customers. The degree of informing the customer depends on the O/T, and the regulations and standards under which the O/T holding org and DUT are under. This form of O/T notice is generated by a technically-at-fault party, (their item is bad. Out of process control), and is more likely to have all aspects of the issue evaluated, mitigated, analyzed, and charted. A due diligence process. There is liability on the part of the O/T holding organization to deal with.
.
So I see 2 distinct forms and methodologies. Both have been correctly discussed. There has been no exact template or form depicted.
There is wiggle room for actual forms in both cases. A phone call is an additional option,
and pressed into use in damage control situations like type#2
Again, only a comment from the origianl thread post person could definitively solve the which one question.............................

We are trying to get a new customer and they asked if we had an out of tolerance report. If a gauge is found to be out of calibration and the parts that were shipped to them are suspect, they want a form that addresses the situation so the matter can be pursued.

I seem to be having difficulty designing one and wondered if anyone had a template.

Seems pretty clear, George. OP make parts. Customer says, "What happens if you ship parts and find later that measuring instrument was out of tolerance/calibration?"

Where did you [George] get the idea OP was in the business of calibrating/certifying instruments?

Re: Out of Tolerance Calibration Report

Amazingly the initial post wording seems to drift when re-asking the question or offering information.
I do not know the Thread Post person, and give them the benifit of re-stating their interest.
I make mistakes, and so do others.
I can see 2 very distinct O/T forms/reports. I do not care or favor one form.
I was summarizing what was writen after, and before me also.
I am cooperating with this thread.
I do notice that your thread comment has a bit of an abrasive tone.
I have no emotional stake in any form type, and am brainstorming, or is it bainfarting, you decide.
I am sure you are absolutely correct, which justifys it? We are being polite here right?
I am trying to be open to other views here.
The idea of not having any O/T Report is then also a view and possible option. Just call.
A phone call might find more acceptance as a first contact and for further discussion of a transmitted
or handed document detailing the issue(s) for common understanding.
