SAE AMS 2750 rev E - Changes Matrix?

[wangjianzhi]

Acording to the requirement of AMS2750E, we calibrate the temperature controller by the three points method, it is necessary to include the following items in calibration report:

f.As found and as left data at each calibration point
g. Offset as found and as left (as required)

There are some kinds of condition to use offset or adjustment, i.e. adjust SAT ,adjust TUS and calibration instrument. if the offset field is zero ,when we calibrate it, it’s OK, we do perform TUS for the this furnace after it’s installed on furnace, TUS result is out of tolerance, in order to adjust TUS, a adjustment is input in offset field, then the TUS is OK. After 3 months, when we calibrate this temperature controller, if we don’t remove the adjustment in the offset field, the calibration result will be out of tolerance, in this case, can you give me a example of calibration report ?

Can someone help?

Thank you very much!!

So...the standard is available.

However:

1.Quote from standard "Changes are extensive and not marked" (they are simply not marked, not by vertical line on the left side or by (R) on the right, nada)

2.There is no redline version available.

I assume that for big companies this should not be a problem while for small companies will evolve into a nightmare.

Taking a pyrometry standard (43 pages) and comparing line by line to find the changes is a real, bigger than life PIA.

Anyone know of someone, somewhere that did the comparison?
