National Institute of Standards and Technology Updated with more uncertainty component columns; added degrees of freedom, with automatic k value and Uncertainty value calculations and rounding to two significant digits
Homepage | GHG Protocol This tool intends to facilitate the aggregation and ranking of statistical parameter uncertainties due to random errors related with calculation of GHG emissions It uses the first order propagation (Gaussian) method This requires that that the distribution of measurement data converges to a normal distribution and that the individual uncertainties are smaller than 60% of the expected mean
Homepage | GHG Protocol Tracking sources of uncertainty is a process that should be done throughout the course of conducting a product GHG inventory Throughout setting the project scope, collecting information and performing analysis, a wide variety of information is addressed and decisions are made that lead to potential uncertainties
National Institute of Standards and Technology Development and modification after limited input File Purpose: Standard Uncertainty Budget Table Template This file was created as a template for any measurement parameter, but assessment is required before use Measurement Range and Parameter: For effective degrees of freedom calculation
ISO This Excel tool enables to implement the calculations described in the Standard ISO 19036 (2019) “Microbiology of the food chain — Estimation of measurement uncertainty for quantitative determinations” The current Version 2 has been prepared by WG 2 Statistics of ISO TC 34 SC 9 “Food products-Microbiology” which is also responsible for ISO 19036 Any questions or comments related to
