Calculation metals tensile & hardness test uncertainty

Hello
I downloaded so many pdf files about calculation of uncertainty for tensile & hardness test.
but this methods are so complicated and have so many effective parametere.
Please shre with me a formula or Excel file for easy calculation of this type of uncertainties.

Time to plunge into this (again)

And have you ever tried to check alignment on a tensile machine?
