The following spreadsheet allows to assess compliance.
You have to introduce (i) SML; (ii) LOQ; (iii) the three migration concentrations, and (iv) the respective measurement uncertainties, u(mi).
The app will calculate the LOD (= LOQ/3.3), and will estimate/suggest uncertainties for the three migrated mass fractions you introduced.
The "red" coloured cells indicate possible non-compliance(s).
For information about the calculations used, proceed to the next page (LINK).
The uncertainty functon used applies to mass fraction below 50 ug/kg (ppb). [Reg. (EC) No 333/2007, https://europa.eu/!JH77YB]
You have to introduce the values one-by-one in the yellow cell ONLY (no copy/paste possible).
Your values will not be saved. The spreadsheet will be reset (= all introduced values deleted) each time you refresh the page.
