Does anyone have a procedure for 2750 D?

Thanks!

:cool:

James, unfortunately we generally do not post copyrighted specifications like that here. That way we don't get yelled at too much!:tg:

However, if you are performing services for an aerospace company, they should provide you one.

I would also think you could ask your inspector who could get you one.:)

Brad,

I am sorry for the confusion. I was looking for a procedure that was written to address 2750 not 2750 itself. Sorry for not being clear on this. Sometimes I write way to fast!

Thanks!

Ahh... sorry about that.

If I remember looking at it, I thought 2750D was fairly detailed in itself. What aspects do you feel are not addressed?

Are you looking for like a uniformity/ instrument calibration procedure?

Since the procedure has to reflect your process and product there is not a single canned one that can work. You can use the AMS to create one if you are familiar with the process. If your are hitting this a bit cold I realy recomend that you take the PRI class on prometry since it will enable you to realy understand why your are doing what is in the procedure.
Trust me when I say that they will expect you to be able to know what you are doing when it comes to TUS and the SAT checks. These are key elements of the audit.

For the sake of ignorant folks like me, what are PRI, "prometry," TUS and SAT?

Since I serve as a VERY GOOD bad example and should have know better

PRI- Performance review institute who administers the Nadcap Program.

SAT- system accuracy test. This is where you show that you instruments are correctly reflecting the temperatures you think you have. This coverers all the various variations in the peices and parts of the system.

TUS- temperature uniformity survey. This is where you demonstrate that the temperatures in all the locations you could place your parts durring processing are with in specification. Basicly makeing sure that there are no hot or cold spots.

Andy - did you mean -


pyrometer -
an apparatus for measuring high temperatures that uses the radiation emitted by a hot body as a basis for measurement.

You are correct in the spelling. For the system it would be Pyrometry.
It is a close competition as to which is my bigest liabililty
Spelling or typing ( better add thinking to that also:cool:)

And since you brought it up.... As you have it stated, you map the realistic working zone of the oven/furnace. If you try to map the entire thing, extreme corner to corner, you will probably have some problems. Saying, if you have a rack in an oven and all parts sit on that rack, then the rack is your realistic work zone. I highlighted all to assure that even if you get one "odd ball" part a year that you remove the rack and put in the part, your work zone has changed.

Also, if you are a typical facility, you probably do work for many different aerospace companies. You will probably want to write your procedure to address 2750 in addition to some of the other little quirks required by the other procedures. You need to "please all", which has become increasingly more difficult given NADCAP. (Have I mentioned my :soap: lately? :lol:)

IMHO...

We spend a lot of space criticizing ISO 9001 and the wording of some of the sections. However, it was at least written for the purpose of creating purposeful system for the particular processes in mind.

2750 was not designed to be audited to the level that NADCAP has made it. I have seen nothing but heartache and frustration.

Thanks everyone for the input.

I have been busy traveling for too long and have not been able to visit the forum latly.

Examples were what I needed.

Thanks!

:D
