The Use of Correction Factors in Pyrometry SATs

In the Nadcap system, the use of offsets/correction factors in System Accuracy Tests (SATs) is discouraged. This is because their application can cause more problems than they solve due to the complexity involved.

To reinforce the Nadcap Heat Treating Task Group’s position regarding the use of offsets/correction factors (other than those for the test equipment that must be used), a software tool has been developed as part of the eQuaLearn Introduction to Pyrometry course. The intent is to illustrate how convoluted and confusing the use of offsets/correction factors can be and to make the class – which is a comprehensive overview of AMS 2750D – more interactive.

eQuaLearn instructor  and Nadcap Heat Treating auditor Douglas Shuler was instrumental in designing this software. He commented “It is common to see suppliers using correction factors to rectify issues but this can have unforeseen outcomes and also doesn’t address the underlying issue of why the adjustment was required in the first place. The use of this tool in the Introduction to Pyrometry class will transform it from instructor-led training to an invaluable interactive session.”
