Calibration and Customer 'Requirements' - Something Stupid Beyond Belief

Re: Something Stupid Beyond Belief -

All of those additional costs should be paid by your customer. You are placing your value on this additional work as the standard, not the customers. Perhaps a similar valve failed in a very expensive way because of poor control of gages. The 8D eventually looks for other places to use this, thus expensive controls on a certain number of valves.
Perhaps I am not being clear here.
The costs were of no concern to me....The customer paid the costs. Likewise I had no problem with the customer coming to observe etc....
We built a good product and never, in more than 20 years at that point, had one of our actuators failed in the field.

To me the problem is that the system described in my posts allowed for a greater, not lesser, chance of test failure due to a bad gage.

Ah well - This was a long time ago and they probably don't do it that way anymore. It just struck us all as exceedingly dumb......

So propose that the gauge testing be performed by an approved 3rd party on your premises. Express your concern that the travel could mess with the calibration, and that it is a less than desirable situation.

We did that and they shot it down. There was a local cal lab that could have been used, but they were commercial and not nuclear approved...
Basically the end user forced this requirement onto our customer because they insisted that the lab doing the calibration of the gages be a nuke approved facility under the control of our customer (who was the one doing the nuclear qualification).

They did this dispite the demonstrable fact that the system we had been using covered all the bases, the gages were checked and rechecked on site and under the supervision of our customer, and that in 20 years there had not been a single problem with one of our units in the field.

Generally these extreme measures just don't jump out on their own like deer into the road - there is an incident that occurs that creates and incredible problem with incredible cost and incredible risk and political pain that somebody somewhere decides they never want to experience again.

You may have never experienced it...and count your blessings - you will never want to. Let you customer assume the risk and accept their happiness over any worry of reasonableness. Not worth losing sleep over. The higher the industry risk, the more likely this can occur.

Fair enough....

Re: Something Stupid Beyond Belief -

Is the accuracy maintained?
Al;

You are so right...

Insurance are for when equipment is damaged or lost but in reality - How do i know that the accuracy of the gages are maintained. (with all the movement and banging around during transportation)

A better way is to find a qualified competent calibration lab to bring their equipment "In-House" and perform the calibration on the gages - thus minimal movement of the gages, less expenses in purchasing another set of gages while the other ones are done, plus additional traveling expenses are incurred.

There are still customers out there that think this way - a good way to win the argument is to show the customer both bill - that usually does the trick

So have the CUSTOMER'S approved calibration lab come to you.

If a properly packaged and handled gage (note: it was hand delivered, not sent UPS) can not be transported without disturbing its calibration - especially hydraulic pressure gages - you have picked an inadequate gage. Again, they covered that issue with a before and after calibration. So, if that is what the customer chooses to do, then fine. No need to show them the bill...they already have it.

I would like to know what data the customer used to make this decision. It seems to be an over reaction to some issue but I would like to know what data was used, if any, to justify the implementation and then continuation of this activity.
