Anyone know of good white papers on SPRT stem correction error? I need good details on tests/evaluation and including them in uncertainty budgets.
From basic to most useful.

I really like the discussion in the last pub on page 22 for Table 9, the vertical temperature differences over the length of the re-entrant well of the fixed-point cells. You can try this with a TPW cell but since the ambient to TPW difference is relatively small it may be difficult to see.
Hope some of this helps, good luck.
Thank you. Got them all. I already have Self-Heating pretty mastered and have a built in calculator added to some of my budget spreadsheets, and getting a lot of the math nailed down in developing uncertainty contributions for Stem/Immersion Error.

Hey, when you have it down are you willing to share your work ( spreadsheets )? I am just starting to work on this myself.
Thanks for posting those links. I hadn't read through the NIST SPRT publication before. Lots of good information.
