Uncertainty Experts - ISO 17025 - If the Distribution is Rectangular

[garyf2017]

Hi, I'm starting to develop our uncertainty measurements and have gone through some trainings and it's really tough...

Am not at all an expert in this field, I wanted to ask how would you consider if the distribution is rectangular,etc...

We're going for ISO 17025...

And also how do I properly consider contributing factors to my uncertainty budget?

TIA...

I would recommend starting with http://publications.npl.co.uk/npl_web/pdf/mgpg11.pdf

rectangular is assumed even across the "board"
triangular center focused
u shaped focused on the extremes
normal 2 is for uc from your standards at k=2
normal 1 for repeatability data

I know that's a simplified rundown but your question is evidence that you require much more training and research.

Hi itsbiodiversity,

Yes thanks, our management would just require us to create a template and once we have a working template with all the formulas input, I think it will work for us who doesn't have much knowledge of the uncertainty measurements.
